1) How to activate the new batteries
Prior to the opening of the new animal cells, plate surface, there will be a certain degree of oxidation. The longer the storage, oxidation more serious. After adding the electrolyte, there will be rapid warming, the charge will show greater resistance to charging difficulties. Therefore, the opening of the new laptop battery  should be done: filling the electrolyte, the static discharge of about 6h until completely saturated with the electrolyte plate, the temperature dropped to below 35 ℃, and then connect the power to charge; charge current is tightly controlled within prescribed limits , such as high temperature during charging, more than 45 ℃, the charge current can be reduced or stopped charging; for 1 ~ 2 times charge and discharge cycles in order to achieve rated capacity.
2) how to conduct the beginning of a new battery charger
The Latitude D830 battery positive and negative power supply respectively, then positive and negative, first with the initial charge current charge to the electrolyte release air bubbles, single-cell voltage to rise to 2.3 ~ 2.4V. Then the current drops to 1 / 2 the beginning of the charging current to continue to charge to the electrolyte release violent bubble, the proportion of electro-hydraulic and voltage remain stable until a continuous 3h. Full charging time is about 45 ~ 65h. Charging process should always measure the electrolyte temperature, if the temperature is too high, can be current half, Latitude D620 battery to stop charging or cooling method, temperature was controlled at 35 ~ 40 ℃. Initial charging is completed, if the proportion of irregularities in the electrolyte, the application of distilled water or electrolyte specific gravity of 1.4 and then adjust the charge 2h, until the proportion of compliance so far. The new battery charge for the first time often do not meet rated capacity, should be charge and discharge cycles. With the rated capacity of 1 / 20 of the current discharge from a single cell voltage down to 1.75V, and then add sufficient charge current. Following a charge and discharge cycles, if the capacity is still below 90% of rated capacity, should make another charge and discharge cycles.
3) How to maintain C1295 battery
a. battery during use, water evaporation and electrolysis of water charging both would reduce the surface, so every 5 to 6 days in summer and winter every 10 ~ 15 days should be checked once a liquid height, and then need to increase distilled water. In addition to leakage caused by lower surface, the are not allowed to add electrolyte, or the proportion of the electrolyte will be higher than 1.300, resulting in shortened battery life. Battery liquid level should be higher than the plate 15mm, easy to spill liquid level is too high, corrosion around the parts, there is likely to positive and negative pile conduction, causing self-discharge; liquid level is too low, easy to expose the upper plate surface, not only HD438 battery capacity will decrease, and the exposed plate will soon be curing.
b. in the use of batteries due to different working conditions, often charging less than the phenomenon of (especially short-distance vehicles). One of the following conditions should be to supplement charge: ① the proportion fell to 1.200 below the electrolyte; ② winter discharge Chao Guo 25%; ③ summer discharge Chao Guo 50%; ④ lights dim; ⑤ weak start. Supplementary charge in two stages. The first stage of the rated capacity of 1 / 10 of the current charge, to a single cell voltage of 2.4V, the electrolyte until the bubble began to release, which normally takes 10 ~ 11h. The second phase will halve the current up to date enough, it generally takes 3 ~ 5h. If the proportion of electrolyte irregularities, should be adjusted, its methods and the beginning of the same charge. c. Winter batteries Y4367 battery , Y4546 battery , Y9943 battery should be noted: ① piling and wire electrical connector to ensure a solid connection, good contact; ② to install insulation in the battery device, so as to avoid the temperature is too low, resistance increases; ③ the proportion of the required adjustment of the electrolyte; ④ in the engine running the engine when you add distilled water to the battery charger in order to avoid uneven mixture of water and electrolytes caused by ice; ⑤ cold start the engine preheating should be carried out, each start-up time of no more than 5s, starting to be repeated intervals 15s, if the three start - unsuccessful, should be carried out checks, do not blindly re-start; ⑥ always keep enough power to charge storage state, to prevent the electrolyte reduced the proportion of the ice, and even damage to batteries.
4) How safe operation when the battery maintenance ThinkPad T40 battery in the warranty, they should observe the following safety requirements: ① moved when the light-light battery can not be skewed in order to avoid electrolyte splashed on clothing or skin, causing corrosion or burns. If they are splash, immediately flush with water. ② Check the electrolyte specific gravity and surface height, so that a little straw to leave the entrance of the electrolyte injection can be, not to mention too high in order to avoid electrolyte spill. ③ to prohibit oil containers and various metal objects on the FRU 08K8193 battery housing. ④ In the preparation of electrolyte should be used when ceramic containers, and sulfuric acid slowly into the water, the absolute prohibition of water poured into the sulfuric acid so as to avoid splashing sulfuric acid burns the skin and clothing, and even the container burst causing the accident.
5) how to make the battery discharge
The new battery to charge and discharge cycles and test batteries ability to work, the basis having regard to discharge a certain standard to test whether the battery rated capacity. ASM 92P1140 battery Rated Capacity 1 / 20 of the current discharge from a single cell battery voltage of each of 1.75V, and 2h at the beginning of each measurement time after discharge voltage, the voltage down to 1.8V voltage drop after the result of faster, should be 15 ~ 20mim a voltage measurement , the voltage down to 1.75V, it should immediately stop discharging, or voltage drop dramatically to the “0″ so burn plate, causing difficulties in the next charge. Discharge many ways (such as the use bulbs discharge, with the variable resistor discharge, discharge with the electrolyte and using a lower voltage battery discharge), can be selected according to specific conditions. In the discharge line, you must access ammeter in series, parallel on the voltage meter so that timely observations voltage value, lost no time to stop discharging.
6) how to reduce battery capacity to do
FRU 92P1137 battery charge, use of time is not long enough to save electricity, starter rotation weakness, difficulty starting the engine, speakers, sound volume reduction, lighting is dim, with high rates of discharge of dollars checklist cell battery voltage is lower than 1. 5V, namely, reduce the battery capacity. Generating capacity should first check whether it is suitable voltage regulator is too low, whether due to long-term storage battery self-discharge, whether to use starter too often, is commonly used because of their low electrolyte liquid electrolyte instead of distilled water by adding batteries, if you do not above-mentioned problems, should open the battery cover and check whether the lack of electrolyte. If the liquid level is too low and too long, so that exposed part of the plate curing, they should check out plate. If the surface of plate showing a layer of white lead sulphate, explained that it had vulcanization. If, after taking the plate, pour the electrolyte in the ThinkPad T60 battery  there is too much off the bottom shell plate active material or other impurities, indicating that these substances caused by a short circuit between the plates, causing inadequate capacity. 7) How to diagnose battery charge storage capability, decrease fault
Drop charge storage capability, commonly known as “run electricity”, the main phenomena are: day before power is still close enough to keep car the next day starter on the weak rotation; engine flameout time for a little longer, then start there are difficulties; lights dim, the loudspeaker does not ring. Should check whether the battery wire Datie. If Datie, available high-rate discharge single-cell voltage meter to check each hour inspections. Such as the start voltage reaches a certain value, it became an instant rapid decline, seriously nowadays down to 0, indicating short-circuit fault between the plates. Open the  D5318 battery cover should be used extract the electrolyte tube, such as the electrolyte turbid, indicating the electrolyte impurities. You should remove the plate, out of partition observation, such as a perforated partition, indicating the failure was caused by perforated partitions. In addition, the surface should also check the battery electrolyte is dirty, and whether there is overflow.
8) How to prevent battery explosion
In the beginning of a new battery charging, discharging process, water is broken down to produce a large number of hydrogen and oxygen, if not promptly released, it will face sparkle 1K500 battery explosion. ① should always check and clear the battery cover of the vent stuffed to ensure that internally generated emissions of the gases out of time; ② the internal battery connections and electrical connections on the pile should be firm, in order to avoid electric discharge; ③ try to avoid piling on the battery power scratch fire, so as not to detonate; ④ first opens the battery segue, and then check the high rate of discharge of dollars.
9) How to use batteries instead of battery
The car is not damaged when the battery or batteries can be used instead of 6 to 8 dry batteries  8N544 battery , 9H348 battery. Methods were: dry batteries together, using cardboard Juan Chengyi body, one end of the Da Tie the other end to pick with a wire coil on the ignition switch terminal, and then quickly shake his hand crank the handle, you can start the engine. When the engine reaches a certain speed, confident that when the generator can supply, and then removed.

An emergency starter battery is dead panic of three approaches

Encountered no electricity or laptop battery failure of the starter motor, which need to be taken when an emergency starter
Carts start is our most familiar and most effective method of emergency start, but it is a means to not have and can not often used, because it would be the engine and clutch have some damage, automatic transmission vehicles, in particular to avoid the use of this method start. Carts start generally require two or more, if only one person would be difficult to implement the driver starting.
Safety
First, Latitude D830 battery to observe the location of road parking suitable for carts start, you can help improve the speed downhill, if the car ahead is uphill, then the cart will move forward very tired, very difficult to improve the speed, so it should be turned around the front to push the downhill direction car. Try not to vehicles and pedestrians in the number of sections carts start, after starting the driver to avoid emergency vehicles, improper accidents.
Slowly Parking
Promotion should be opened before the vehicle ignition switch, to a considerable speed, it will be put on the two transmission gear, and then quickly release the clutch pedal and the fuel. Once the engine starting, shall be promptly depresses the clutch pedal, while controlling the throttle, to prevent engine flameout, Inspiron E1505 battery and then gradually stop.
When the battery power is low, this method can be used an emergency starter.
The two vehicles approached, until adequate jumper cable to connect two Latitude D830 battery positive and negative. Should be taken to ensure that cars could not touch, only allowing the use of sufficient bearing capacity and the cable with insulated jacket. If the battery provides power to the installation location on the vehicle directly across inconvenient access, you must use a tool to remove the batteries.
To determine the positive and negative terminals of two batteries  FRU 92P1131 battery , FRU 92P1133 battery , FRU 92P1137 battery, use a cable to the positive with positive, negative and negative respectively, are linked. Should pay attention to battery positive and negative must not be mistaken, but also to ensure a reliable cable connection. Layout direction of a good cable to prevent starting when the cable and tape or fan Guaceng.

Use rechargeable batteries
Use rechargeable Inspiron 1300 battery for notebook computers, one of the relative advantages of the desktop, it can greatly facilitate a variety of environments the use of notebook computers. Introduced the first battery is nickel-cadmium batteries (NiCd), but this battery has a “memory effect”, each charge shall be required before discharge, very easy to use, and soon was nickel-metal hydride battery (NiMH) replaced, NiMH not only failed to “memory effect”, but can make more per unit weight of 10% of the electricity. The most commonly used  Inspiron E1505 battery is lithium-ion battery (Li-Ion), it is also no “memory effect”, as compared with the NiMH per unit weight gain more power, the price twice as high than the NiMH. In the same weight, this three kinds battery is 1:1.2:1.9 ratio.
Notebook computer batteries currently used in three kinds of main categories: 1. Nickel-chromium batteries, 2. Ni-MH battery, 3. Lithium battery; they are generally expressed as: Ni-Cd NI-CD, Ni-MH NI-MH, Lithium-Ion battery LI.
The purchase or replace the battery when the laptop for many users, the “batteries” Inspiron 9300 battery , Inspiron 9400 battery may be unfamiliar. The outset, batteries and battery are two concepts. A battery is composed of several slightly larger than the thumb, cylindrical, height of about 7,8 cm, voltage is 3.6v of small units. They are the batteries, just like a small battery, through the series combination, that is, we see the battery has. Then talk about how to determine if the battery is several cores:
One way: Disconnect the battery to the number of contacts to see him, there are a few of the tens of cores. But this is a “minister” approach. Let’s take a look at “Cao Chong” is how, “said the elephant”: the look of your battery nominal number of v, such as 14.4v, and then divided by 3.6 to be 4, then proved to be four batteries together in series. And then take a look at the capacity of the  Latitude CPX battery , Latitude D500 battery  block, for example 3800mAh, then prove that the above mentioned two sets of batteries in series, because the small battery capacity is 1500-2000mAh, even more, to be two to reach 3800mAh. According to these two judgments, then the battery is 4 × 2 = 8 cores.
The composition of laptop battery
laptop battery  from shell, circuit boards and batteries, belonging to lithium-ion battery. People are talking about batteries in general refers to the number of batteries within the battery, mAh refers to the laptop battery capacity.
Mainly by the protection circuit board (or the secondary protection circuit), and the capacity of directed circuits of two parts, notebook battery charge and discharge and safety management.
Laptop battery standby time mainly by the mAh value to decide. Under normal circumstances, a few more batteries, mAh value is greater the longer standby time.  Latitude D830 battery life mainly by the charge and discharge times to measure the quality of the products are generally eligible for 500-600 times. Therefore, the effective use of laptop batteries within a period of two years, expired the battery will be aging, standby time affect the sharp decline in the mobility of notebook computers.
Laptop battery tips
In fact, how to make good use of laptop batteries  92P1102 battery , 08K8192 battery , 08K8193 battery , how to extend their use of time and the use of life and so on, is undoubtedly the troubled minds of the majority of notebook users, a problem, the use of laptop batteries There are many methods and techniques, which requires us to usually use more learning and application.
(A) rapid access to hibernation
Temporary non-use of laptop computers, in order to conserve battery power, we can set the power management program, allowing the system to enter sleep mode after a period of time, but this is a shorter or longer will have to wait a few minutes, there is no way to make laptop computer system immediately enter the sleep state?
Notebook computer system to enable quick access to dormant state of a simple method is to directly close the display. Press the display would require little effort, you can make notebook computers into sleep mode immediately and effectively conserve ThinkPad R50 battery power. When you need to re-used time, as long as the opening screen, the system will automatically return to pre-operational state.
(B) the screen-saving mode
TFT screen is the largest notebook computer power components, in order to reduce its use of the battery when the power consumption, notebook manufacturers have devised ingenious schemes, but in general are based on the lower screen brightness, and even turn off the screen method.
In some notebook computer’s power management settings you can customize the brightness of the screen, most of notebook computers by a specific shortcut keys adjust screen brightness, generally 6 to 8-level brightness adjustment.
(C) energy-saving settings
Desktop machines using alternating current, most people may not be the computer attached great importance to energy-saving features, but need to use battery-powered notebook computers, the use of energy-saving features should be taken seriously ASM 92P1138 battery , ASM 92P1140 battery . How to design computer hardware more energy-efficient, this is not a user problem to be solved. The user can do is set up on the computer the effective use of energy-saving option.
Energy-saving settings require the user to adjust two: First, the computer’s BIOS setup program on the energy-saving mode in the settings; most important thing is there are many energy-saving in the operating system settings and operations. In the practical implementation of computer systems, Windows systems should take precedence over energy-saving settings in the CMOS settings.
1. BIOS in the energy-saving settings
In the CMOS settings, most had a “Power Savings”, which can choose to “Maximum Battery Life” and “Maximum Performance” and other options. “Maximum Battery Life” is the default power saving mode setting. Notebook computer power saving mode in several states, such as the Idle Mode Idle Mode, Standby Mode standby (wait) mode, Suspend Mode suspension (sleep) mode. Notebook computers, these settings have been able to regulate power consumption, mainly in the computer into energy-saving state, the timely closure of some without the use of the system equipment. If the wait state, turn off the screen and hard drive; into hibernation, apart from a close monitor and hard drive, but also the contents of memory can be saved to the hard disk, ThinkPad T60 battery , ThinkPad T60p battery  the basic maintenance of the entire computer system shut down, once activated, or restart the computer, desktop will be accurately restored to pre-hibernation state. The energy-saving settings in the CMOS, mainly set by the Idle Mode to enter Standby Mode to Standby Timeout time, set to enter Suspend Mode from Standby Mode to Suspend Timeout time. Phoenix BIOS notebooks are most common. Different energy-saving BIOS settings may be somewhat different, it should carefully read the screen prompts.
2. Windows in the energy-saving settings
For the average user, in the Windows system to operate a better understanding of energy management can be simpler. Windows Help file, in the “management of hardware and software” entries, there are two notebook computers with energy-saving elements relating to: “Managing energy consumption” and “use of portable machine” in the “management laptop on the power.” Energy-saving settings during Windows, should read the contents.
In the Windows “Control Panel”, click “power management”, you can open the “Power Management Properties” dialog box. In the “Power Management Properties” dialog box, should be “power scheme” is set to “Portable / Laptop” and reasonable arrangement “system waiting for”, “close the Monitors”, “Turn off hard disks” and other options for . Different computer can control the option to have some differences, the new factory and the latest computer software will be more workable options, detailed settings should be based on the computer’s own features and Windows Help files to carry out.
In addition, if your laptop built-in infrared port, not the time to ban it, it can be extended  ThinkPad T40 battery life.
(D) alarm settings
Set battery alarm in time to give prompt the user to save the information. Way is to click on Open “Control Panel”, double-click “Power” option, point “alarm” menu bar, “low-battery alarm” column, Windows 98 default is 10%, “a serious shortage of the battery alarm” column, Windows 98 default is 3 %, which may make the appropriate modifications as needed. Click both the [alarm response] button, the “voice alert” and “displays the message” are selected, “the power level” may from time to select. Alarm limits so that when the battery is used, it will pop up a warning window, and the alarm buzzer sounds to alert the user to save information on a timely manner. Finally click [OK] button to exit the power management settings.
(E) open the energy-saving function
In the “extended  Inspiron 1520 battery life technology” section, we have introduced energy-saving feature is the use of a CPU technology, which allows the performance make notebook PCs to play with their battery life between the time to achieve the best balance.
Most new models of notebook computers both in the BIOS of the CPU energy-saving technology have given the support, by default is turned on, if not open as long as the enter the BIOS will support the option to open it OK.
(Vi) The use of third-party software to monitor battery status
In addition to Windows built-in power management features, there are many utilities available to monitor the battery condition. For example, PowerCenter is a power monitoring tool available for free download (http://me MBers.xoom.com / TimothyBug / powercenter / index.htm). Only 800KB, is designed for notebook computer services software. In addition to the amount of PowerCenter shows the percentage of Inspiron E1505 battery , but also to show the actual time and hours of time can be used.
PowerCenter total of three kinds of display.
(1) FullDisplay: In the open window displays detailed information, including the use of battery or AC power, the battery percentage and the remaining time available.
(2) CompactDisplay: in use is always at the top of the window display.
(3) MinimizeDisplay: make PowerCenter reduced to the Windows task bar, display the information is relatively simple.
PowerCenter is also attached to a control center, can be made up to six kinds of warning. When the battery - down to a certain level, a timely warning to the user, save the file being processed. In order not to waste electricity and CPU resources, PowerCenter automatically detect the battery status changes.
(G) intentionally run out of battery
Run out of battery on a regular basis in order to ensure a full charge. If you need to completely run out of battery power in the specific practice is: In the Power Management dialog box, select Battery Drain this particular power mode, all of its 3 Running on Batteries options are set to Never, this notebook computer on the will continue to run. Select the mode, and then enter the Alarms tab to lift the Low Inspiron 6000 battery  and Critical Battery Warning check box is a check mark (so, when the battery power is low, the machine will not enter the suspended state). Next, let the computer run the CPU-time tasks, such as the computer automatically run a number of computational complexity of the 3D demo program, so soon run out of battery power remaining, of course, these disposal not forget to unplug the AC plug

On the use of lead-acid battery maintenance

Posted by admin on August 24, 2009
Dell laptop / No Comments
Lead-acid battery is a farm trucks and tractors an important component of the electrical system. Battery life with the use of maintenance is closely related to the use of improper maintenance will cause early damage to batteries Inspiron E1405 battery , Inspiron E1505 battery . Therefore, a careful use of good battery maintenance is very necessary. In addition, the battery sometimes in the course of some damage, the user to take some temporary measures, real-time to repair, to avoid adversely affected by farming season and reduce losses.
First, the use of lead-acid battery maintenance
1, the correct installation Datie pole piles. The present agricultural vehicles and tractors on the generator with the rectifier is equipped with the battery negative Datie, and DC generator with laptop battery  is used in cathode Datie, can not hold against; otherwise the former will burn silicon diode, which will burn regulator contact. Lead-acid battery pole pile marked “+” sign is positive, marked “-” number is negative. No tags, you can identify by the following characteristics: a very thick pile is positive, smaller is the negative; great pile on the oxide is more positive, less is negative; very dark brown pile is positive, pale gray is negative; also available from the poles leads to a pile on each wire, 1K500 battery , 1X793 battery inserted in the same acid in the cup, there are a large number of bubbles produced is negative.
2, do not make excessive battery discharge. Use electric starter starts, each operation shall not exceed 5s; the first time you start Buzhe should be separated 2-3min and then start-up; three times to start Buzhao, should check the reason, can no longer start a row.
3, the winter starts, the engine to heat water, oil should be pre-heating to reduce the load to start the motor and reduce the 8N544 battery  output current. In addition, there is no loose wiring clip case, do not force moving wiring chuck in order to avoid a very loose pile.
4, proper maintenance of battery should do the following:
(1), always keep batteries  HD438 battery , HF674 batter clean. The outer surface of battery electrolyte spills, dirt, dust, which would cause short-circuit discharge must always wipe clean. Polar head piles and wiring should be kept clean, good contact, and coated with Vaseline to oxidation. Battery lid vent should be kept open in order to avoid gas expansion to enable battery shell rupture.
(2), batteries installed in the locomotive must be fastened securely, and to have anti-vibration pad, so as to avoid driving shattered battery shell. When they find the shell cracking or electrolyte leakage should be timely maintenance.
(3), regularly checked the electrolyte fluid level. Inspection, the application of two openings of the glass tube, insert a finger after a single cell block singalong, and then out observation, is strictly prohibited the use of metal utensils. Surface is insufficient, it is timely to add distilled water; as electrolyte leakage or overflow when the original density of the electrolyte should be added. Add distilled water, it should start the engine to recharge, so that electrolyte mixing.
(4), regularly check the ThinkPad T40 battery deposit of electricity. Application of electrolyte density meter or the discharge fork measurements. When none of these devices can also be speaker volume or the intensity of light to check. Prohibit the use of short-circuit spark discharge to see the size of ways to check to ban the use of tools and objects can be conductive on the battery on the battery off to prevent short circuits.
Second, the immediate lead-acid batteries commonly damage repair
The use of the process, if the battery were damaged, the user can take some temporary measures to repair immediately to an emergency, conditional again when a thorough restoration.
1, very pile ablation, fracture. When the great pile ablation, broken after the repair can be planted wire method. Damage to the very first pile cut from the root level, in its cross-section center drill? 5mm, depth 15mm holes, screw into the M6 × 30 hexagonal screws. The iron pipe on the horn to do a very pile on the molten lead poured into the heated water, after cooling tubes can remove the speaker.
2, shell, cover cracks. If it is found in the vehicle was moving in time, they should first plugging. The side of the battery does not drain the side and wipe away the electrolyte leakage in the ASM 92P1138 battery cover at digging some sealing material, in the exhaust pipe after Hongre Trap. If the slab cracks, the application hacksaw sawing supplemented after the V-groove. For the small cracks, can be used adhesive bonding. Approach is to first crack at local heat until softened after the knife cut into V-shaped crack along a small groove and then with a good resin to be squeezed clay patch Department, Tu Ping, after paper stickers, ready to put its own house sclerosis immediately after use.
3, plate short circuit. Multi-partition is damaged or the bottom of the sediments due to too much lead. Ruoyin partition is damaged, should open the battery, replacing bulkheads. If only a single cell of the partition is damaged, can be removed separately, a single cell of the plate group repairs. Ruoyin too much sediment should be poured electrolyte, cleaned with distilled water after repeated charging.
4, very active material off the board. Active material shed much, they can continue to use after the removal of sediments.
5, plate curing. More than a long-term due to battery discharge in a discharge or semi-state, produces a very thick plate-shaped grains caused by lead sulfate. If curing is not serious, can be used for recharging small current long ways in which the active material recovery, methods of operation are as follows: first by 20h-discharge rate XD736 battery discharge end power, poured out all the electrolyte, washed several times with distilled water and then injected into distilled water to the standard liquid. The second phase of the initial charge with the charge current charge, and to keep measuring the density of electrolyte, when the density increased to 1.15g/cm3 stops charging. Then pour the entire inside of a single electrolyte, and then injected into distilled water and continue to charge. So over and over again, until no longer be increased until the density of the electrolyte. Last to conduct a discharge, and then its fully charged, the electrolyte density can be adjusted to the desired value. The charge to the vulcanization of  GW240 battery , its capacity should be restored to the rated capacity of more than 80%. Otherwise, it should be further carried out a number of charge and discharge processing.
6, sealing plastic rupture. If the small cracks that can be used hot iron hot together. If the crack larger, severe electrolyte leakage, should eliminate, re-casting. In order to seal the shell material and a reliable combination of pouring Department should be cleaned with cotton dipped in alkaline to acid.
7, battery circuit. After the  Precision M65 battery of a single-cell circuit can be used across the open circuit wires thick enough to single-cell temporary use.

Laptop battery problems again? Lenovo today announced the recall of all

Posted by admin on August 17, 2009
Dell laptop / No Comments
Yesterday, the Lenovo Group of the official website linked to the issue of a replacement laptop battery free of charge information. Although the relevant responsible person stressed that the issue of batteries does not pose a security risk, and intention to play down the incident, but still caused concern to the industry.
ThinkPad users as a result of a small number of reports, there can not charge battery or low battery capacity, such as short battery life or a sudden drop in power the question of scale. Legend explains that “the battery can not repair the damage” or “battery can not charge” the emergence of information means that the Latitude D830 battery can not discharge or charge. This is a permanent battery failure, but does not constitute a security risk. And low battery power, it means that time is short battery life, a sudden drop in the power scale.
If battery failure due to this problem, Lenovo will be a free replacement battery. “The official line of Lenovo Group, Lenovo areas indicate the scope of the replacement of batteries, announced the recall ThinkPad R60 battery , R61, ThinkPad T60 battery, T61, X60, X61 laptop battery part number. Lenovo said that all official information to explain the replacement of the main , is not to say that the above-mentioned 10 models of all models have the issue of batteries. users through the installation of diagnostic tools to check the battery, it still can not predict the number of batteries ASM 92P1138 battery , ASM 92P1140 battery , FRU 92P1131 battery  need to be replaced. windows users can use this tool to detect, to to determine whether battery failure due to this problem and to comply with the conditions of a free replacement.

With extremely long  laptop battery life, strong performance, stylish looks, and a host of business-friendly features in a lightweight chassis, the 13-inch Dell Latitude E4300 provides a compelling option for highly mobile business users. However, the E4300’s performance and long Inspiron 9200 battery  life come at a premium. Though the system starts at $1,549, our configuration came with extras such as an extended battery slice and a high-performance solid state drive, pushing the MSRP of our review unit up to a pricey $2,794. However, if you’ve got the budget, you’ll find few systems with this combination of portability, endurance, and power.

Design

The E4300 is one of the most stylish business notebooks we’ve tested. The polycarbonate and aluminum chassis features a tastefully minimalist design with squared edges, with a handful of blue status lights dotting the top of the keyboard. Our review unit was black, but unlike most business notebooks, the E4300 is available in blue and red. The standard six-cell Latitude CPi battery is a blemish on the uniform design, as it not only bulges out uncomfortably from the back, but also is painted in a mismatching silver.
 
With its lid closed, the E4300 measures 1 inch at its thinnest and 1.3 inches at its thickest points. With the optional battery slice attached to the bottom, the thickness increases dramatically to 2 inches at its thickest. The E4300 weighs a full 5.2 pounds with the slice attached, and 3.8 pounds without it. The Lenovo ThinkPad X300 and X301, by comparison, weigh only 3.3 and 3.4 pounds, respectively, when equipped with their six-cell batteries  HD438 battery , HF674 battery , HP297 battery .

With the auto manufacturers in North America to launch the next new car will be designed and assembled into a battery pack of lithium-ion batteries, laptop battery electric vehicle package in the region of the first part of the infrastructure put in place soon.
Now, with more and more electric cars will soon put into operation, together with the U.S. government allocated 2.4 billion U.S. dollars funded the development of a new generation of electric vehicles in North America are ready to enter the lithium-ion battery production in the next phase.
In this, there are a battery manufacturer will spend nearly 400 million U.S. dollars to the  Inspiron E1505 battery production from the current suppliers in Asia to the United States, Michigan.
CompactPower Inc. The company is already in Troy, Mich., has a XPS M140 battery  manufacturing plant by the end of 2010, the plant will have an annual design and assembly of 10,000 lithium-ion battery pack capacity. The first battery plant will be supplied to GM’s Chevrolet Volt all-electric vehicles. General Motors will build its own battery manufacturing plant, and ultimately used in car Volt battery supply will be internal.
General Motors has also been designated by the CPI, headquartered in Troy Corporation - part of South Korea LG Chemical Co., Ltd. - for the future production of an unnamed Buick Motor Car Plug-in supply of mixed lithium-ion batteries, the car will be listed in early 2011.
August 6, the company in the United States CEOPrabhakarPatil the Center for Automotive Research in Traverse
City held its annual seminar on the management of an interview, said that in the orders of General Motors, CPI will be the production of batteries C1295 , D5318 , 6Y270  , but also to build a new lithium-ion battery manufacturing plant in order to further expand its production capacity in North America.
Patil said that the 2500-5000 cost 10,000 U.S. dollars and will take 6-9 months for completion of the battery pack can be different from the factory, the battery plant is a single cell components, including the CPI
Internal battery for each partition of the polypropylene film developed proprietary coating. Battery production plants much more complex, but also the need to establish a clean-room capacity, so its cost is also higher.
CPI companies obtained from the federal government of the 151.4 million U.S. dollars grant to build its Michigan plant cells. At present, the company is on Michigan’s Holland, Pontiac and St.
Clair visit these three places, the final site will be selected.
U.S. Department of Energy also funded the construction of other ThinkPad T40 battery  factory, including Johnson Controls, A123SystemsInc. Company, EnerDel Inc. Company and General Motors Corporation, of which 105.9 million U.S. dollars will be allocated funding to General Motors in Detroit suburb of Brownstown Township to build the battery Group production plant will be used in LG battery supply and CPI.
Patil said the federal funding alone is not a business so that ASM 92P1140  production will be moved out of Asia. CPI also require long-term customers.
Patil said: “Only the availability of funds is unable to establish such production. Also be a certain production scale, Latitude D620 battery and the business case for sustainable development. And we are in a position of great advantage, because the [mass production version] Volt and [Buick] signed the contract so that we firmly believe that this will become a new business of sustainable development. “
