1,High Energy Density Mobile Phone Battery

The weight of a li-ion Nokia BL-4B battery is approximately one half compared to nickel-cadmium mobile phone battery or nickel-metal hydride mobile phone battery of similar capacity.Moreover,the volume of the mobile phone battery is 40% to 50% smaller than that of a nickel-cadmium of mobile phone battery and 20% to 30% smaller than that of a nickel-metal hydride mobile phone battery

2,High Voltage Mobile Phone Battery

A single li-ion mobile phone Nokia BL-4B battery has a voltage of 3.7V,which is equal to either three nickel-cadmium of mobile phone battery or nickel-metal hydrided of mobile phone battery connected in series.

3,Pollution-free Mobile Phone Battery

The li-ion mobile phone battery does not contain any polluting substances such as cadmium,lead,mercury,etc.

4,Non-metal Lithium Mobile phone Battery

The li-ion mobile phone battery does not employ any lithium metal.The li-ion mobile phone battery is not governed by aircraft transportation rules relating to carring li-ion mobile phone battery in passenger airplanes.

7,Fast Charge Capacity Mobile Phone Battery

The li-ion mobile phone 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 402V per cell.
