16340 300mAh 3.7V Lithium Battery Rechargeable Battery Laser Pointer Flashlight Battery Product Introduction and Advantages

1. High energy: lithium-ion batteries have higher weight-to-energy ratio and volume-to-energy ratio;

2. Low internal resistance: The internal resistance of the battery is reduced from the ohm level to the milliohm level, improving the power conversion efficiency;

3. Lithium-ion batteries have no memory effect and can be repeatedly charged and discharged;

4. Long cycle life: the cycle life is increased from 500 times to more than 1000 times;

5. Environmental protection: the product does not contain harmful metal cadmium (CD), and nickel (NI) is environmentally friendly;

6. Small self-discharge: lithium batteries can be stored for a long time due to small self-discharge, and the monthly self-discharge rate is reduced from 15% to about 8%;

7. High voltage: The voltage of a single lithium-ion battery is 3.7V, which is equivalent to the series voltage of three nickel-cadmium or nickel-hydrogen rechargeable batteries.
