Features

1 Standard Charge

This “Standard Charge” means charge the cell at charge current of 1.7A and constant voltage 4.2V at 23°C, 0.02C 68mA cut off.

2 Standard Discharge Capacity

The standard discharge capacity is the initial discharge capacity of the cell, which is measured at discharge current of 0.2C 0.68A and 2.65V cut off at 23°C within 1h after the Standard charge. Standard Discharge Capacity ≥ 3.35Ah

3 Rated Discharge Capacity

The rated discharge capacity is the initial discharge capacity of the cell, which is measured at discharge current of 1C 3400mA and 2.65V cut off at 23°C within 1h after the Standard charge. Rated Discharge Capacity ≥ 3.25Ah, 97 percents of 3.35Ah

4 Initial internal resistance

Initial internal resistance will be gauged at AC 1k Hz afterward Standard charge. Initial internal resistance less than 35mΩ

5 lifetime

Each cycle is an interval between the charge (charge current 1.02A) and 0.1A cut off and the discharge (discharge current 3.4A) and 2.65V cut off.

Capacity after 500 cycles. Capacity ≥ 2.01Ah (60 percents of Standard Capacity)
