we are factory,supply Notebook battery producer,factory,laptop battery,laptop batteries for you. 1. High Energy Density Laptop Battery The weight of a li-ion of laptop battery is approximately one half compared to a nickel-cadmium of laptop battery or nickel-metal hydride of laptop battery of similar capacity. Moreover, the volume of the laptop battery is 40 to 50% smaller than that of a nickel-cadmium of laptop battery and 20 to 30% smaller than that of a nickel-metal hydride of laptop battery. 2. High Voltage Laptop Battery A single li-ion of laptop battery has a voltage of 3.7V, which is equal to either three nickel-cadmium of laptop battery or nickel-metal hydride of laptop battery connected in series. 3. Pollution-free Laptop Battery The li-ion of laptop battery does not contain any polluting substances such as cadmium, lead, mercury, etc. 4. Non-metal Lithium Laptop Battery The li-ion of laptop battery does not employ any lithium metal. The li-ion of laptop battery is not governed by aircraft transportation rules relating to carrying li-ion of laptop battery in passenger airplanes. 5. Long Cycle Life Laptop Battery Under normal conditions, the li-ion of laptop battery has a life of more than 500 charge/discharge cycles. 6. No Memory Effect Laptop Battery The li-ion of laptop battery is free from the so-called memory effect, a phenomenon seen in nickel-cadmium of laptop battery in which the apparent battery capacity decreases when shallow charge and discharge cycles are repeated. 7. Fast Charge Capacity Laptop Battery The li-ion of laptop battery can be fully charged in 1 to 2 hours, using a constant-current / constant-voltage (CC/CV) type dedicated charger with a rated voltage of 4.2V per cell. Laptop Battery Applications The rechargeable li-ion of laptop battery shows great promise as a battery to meet such requirement. This new li-ion of laptop battery technology has excellent features, such as: high energy density, high voltage, good storage and cycle life characteristics. Our li-ion of laptop battery is use to replace the international laptop brands such as Apple, Lenovo, Hp, Toshiba, Sony, Dell, Asus, Hasee, Acer, Gateway, Benq, Hedy, Founder and so on.
