Toshiba in fuel cell aspects quite lead, and samsung have also increased the strength, this area of research, it for laptop Q35 recently launched a new “battery”, make the laptop in the case is no external power supply many work longer hours.

Samsung says this type of fuel for 650Wh/L battery performance, almost four times the general products, can reserves 12000Wh topped breathtaking, the digital means, without recharging cases, this kind of “battery” normal usage a month for laptop! This “normal use” means is eight hours a day, every day.

In addition, this type of battery is also very “quiet”, and the sound of the absolutely does not exceed the notebook itself. The only drawback is that it is not so much a bit big,, rather than a laptop battery for the base, the characteristics of notebook “portable” is, indeed, a little disproportionate, but with process improvement, size should nothing big problem.

Fuel cells for fuel and oxidizer through chemical reaction chemical energy directly into electricity, no middle shift the energy conversion can be as high as 50%, the efficiency of the link, if will waste heat recycle, efficiency may reach more than 80%. In addition it also don’t pollute, running to restart from interrupt transmission capacity picks up speed, and can be used in a short time increase or decrease the power output, can be considered as the next generation of batteries.

April 26 , portable applications made many of the unique requirements of battery: The battery must have a high energy density, portable applications that provide a steady stream of energy (burst or continuous mode); batteries lighter, smaller footprint; battery should be able to secure use and to prevent possible abuse, and has indefinitely idle life; Finally, the battery should have a very low cost. Because lithium-ion or lithium polymer batteries can satisfy most of these requirements, they have become the preferred battery for portable applications

Compared with other existing batteries, rechargeable lithium-ion batteries have several advantages, making them more suitable for portable power sources. They can provide higher energy density (up to 200 Wh / kg or 300-400 Wh / L) and higher battery voltage (4.1 volt battery carbon anode, graphite anode cell to 4.2 volts). Lithium-ion battery can be rectangular shape and has a longer recharge to maintain or idle life and a higher number of charge cycles.

Chemical lithium-ion battery energy density and higher and higher battery voltage allows us to create portable applications smaller and lighter batteries, lighter and smaller power supply for portable applications is often critical. However, to make full use of the battery capacity or extend battery life, must be very strictly controlled charging parameters.

Battery life is a reasonable choice of the key charging parameters, such as current, voltage and temperature. During charging, the voltage applied to improve the accuracy of the efficiency and extend battery life of the battery has a very important role. Over charging will lead to over charge termination voltage, which in the short term will increase the battery power supply, but in the long run will lead to battery failure and a security issue.

Termination charge for every 1% increase in voltage, the battery initial capacity will be increased about 5%. The obvious effect of short-term gain would be the battery charge / discharge cycles have serious consequences.

According to the latest news reports: Recently, the Internet came the ultimate ultraportable ThinkPad Lenovo notebooks new X1, whole thickness of 21.5mm, which this is known as “whole new generation ThinkPad “, with embedded battery design, the user can not change their own , Its price of about $ 3,000, is expected to soon officially released.

According to reports, in the configuration, this notebook is equipped with Core i5 = 2520M processor, 8GB memory, 160GB solid-state hard drive, integrated graphics, 13.3-inch Corning Gorilla gorilla glass screen, 1366×768 resolution. Not only with the battery charge rate 2.5 times faster than conventional batteries, but battery life is 3 times normal, in addition, RapidCharge technology allows the battery in half an hour filled with 80%.

Uninterruptible power supply (UPS) batteries are usually able to use 3 to 5 years. Life expectancy depends on several factors, including the use of capacity (equipment must be battery-powered model in number) and other environmental factors. Here are some of your equipment to ensure the best use of the principle of life expectancy:

 1. to ensure that your APC UPS Store in a cool, dry and well ventilated location. Ideally, UPS temperature of the placement should not be above 24 degrees Celsius. Meanwhile, for ventilation purposes, are set aside each side about 1 to 2 inches of space, facilitate air circulation.

 2. Every year, only when necessary for 1 to 2 times UPS run time calibration. Sometimes, you can perform run-time calibration to verify whether your running time is sufficient. However, frequent calibration will reduce run-time implementation of APC battery life expectancy.

 3. Do not store batteries APC long time. New battery can store 6-12 months. After this time, it should use the battery as soon as possible, otherwise they will lose their large storage capacity. Not recommended for storage of used batteries.

 4. loads do not exceed the rated capacity of UPS equipment, 80%, as this will result in reduced running time. Load increases, the running time will be reduced accordingly. If the power can not supply full load and the UPS will soon run out of battery power and release it, which would reduce battery life expectancy. Note: To ensure longer battery run time, do the laser printer connected to the UPS battery backup outlets. Ensure that the laser printer using the “Surge only” outlet (using the appropriate model). For those who do not “surge only” outlet UPS, suggested that the laser printer is connected to a separate APC surge suppressor.
