Information

That batteries have a finite life is due to occurrence of the unwanted chemical or physical changes to, or the loss of, the active materials of which they are made. Otherwise they would last indefinitely. These changes are usually irreversible and they affect the electrical performance of the cell. This page describes the factors influencing battery life.

The following is a report on the performance of BFN battery in charge and discharge cycle of 8C at room temperature.

 

Determination criteria:

Capacity attenuation ≤20%, internal resistance rate ≤25%

 

Appropriate Test the Conditions:

1 constant current 2500mA charging, upper voltage 4.2v, charging time 80min;

2.Charging at constant pressure 4.2v, charging time 50min, cut-off current less than or equal to 0.02c;

3 constant current 20000mA discharge, lower limit voltage 2.75v, discharge time 10min;

4. Let it rest for 10min;

5. 300 cycles;

6. Test cabinet: bs-9300r test cabinet;

7.Test date: August 03, 2019.
