Specification

Standard charging

It is to charge the cell CC and CV with charging current 0.5C (1.5A), constant volt 4.2V and 0.15A cut off at CV mode at 25℃ for capacity

Rapid charging

This is to charge the cell CC and CV with charging current 4A and 0.1A cut off at 25℃

Nominal discharging capacity

The standard discharging capacity is the initial discharging capacity of the cell, which is measured with discharging current at 0.6A (0.2C) with 2.50V cut off at 25℃ within 1hour after the standard charge.

Nominal discharging capacity exceed 3Ah, comply to min capacity of IEC61960 standard.

Standard rated discharging capacity

The standard rated discharging is the discharging capacity of battery cell, which is gauged at discharging current of 10A and 2.5V cut off at 25℃ within 1hour after the standard charge.

Standard rated discharging capacity more than 2.9Ah

Initial internal resistance (IR)

Initial internal resistance measured at AC 1kHz after standard charging

Initial internal resistance less than 26mΩ

Cycle life

At standard charging and maximum continuous discharging

Capacity more than 1.8Ah (60 percents of nominal capacity at 25℃)

Storage characteristics

Standard rated discharging capacity after storage for 1 month at 60℃ from the standard charged state is ≥ 90% of the initial 10A discharging capacity at 25℃

Battery cell voltage at shipment
