Advantages of Li-ion Battery:
1).High Energy Density
The volumetric energy density of EWT Li-ion Battery is approx. 4 times than that of Ni-Cd and 2 times than that of Ni-MH Rechargeable Battery.
2).High Output Voltage
The operating output voltage is 3.6V, three times higher than that of Ni-Cd and Ni-MH cells.
3). Long Cycle Life
Recharging properties allow more than 500 repeated charge/discharge cycles.
4). Pollution-free
The lithium battery does not contain any polluting substances such as cadmium, lead, mercury, etc.
5). Non-metal Lithium
The lithium battery does not employ any lithium metal. It is not governed by aircraft transportation rules relating to carrying lithium batteries in passenger airplanes.
6). No Memory Effect
The lithium battery is free from the memory effect, a phenomenon seen in nickel-cadmiumin which the apparent battery capacity decreases when shallow charge and discharge cycles are repeated.
7).Fast Charge Capacity
The lithium-ion battery can be fully charged in 2 to 3 hours, using a constant-current / constant-voltage (CC/CV) type dedicated charge with a rated voltage of 4.2V per cell.
8). Excellent Security
Each cell has an additional saftey device to ensure its security as proved by the following safety tests:
Destruction test Over charge test Needle penetration test
High temperature test Burning test Short circuit test.
