Test Methods and Condition

Criteria

0.2C Capacity

After standard charging, rest battery for 10min, then discharge at 0.2C to voltage 3.0V, record the discharging time.

≥300min

1C Capacity

After standard charging, rest battery for 10min, then discharge at 1C to voltage 3.0V, record the discharging capacity.

≥54min

Cycle Life

Constant current 0.5C charge to 4.2V, then constant voltage charge to current declines to 10mA, rest 10min,constant current 0.5C discharge to 3.0V,rest 10min. Repeat above steps till continuously discharging capacity higher than 80% of the Initial Capacities of the cell.

≥300 times

Capability of keeping electricity

20±5°C, After standard charging, rest the battery 28days, discharge at 0.2C to voltage 3.0V, record the discharging time.

≥240min

Advantage

1.Double protection IC(usually Seiko) to avoid over-discharging, over-charging, and short-circuit.

2.Gilded and flexible connecter, better conductive properties, not easy to rust.

3.Safety and stability: Hi-tech lithium-ion.

QC

First, our QC will do the overcharge and over-discharge testing of battery with PCM. Only the testing result of both battery core and PCM is qualified, can we start assembling. Then we test our battery again. When the quality and performance is guaranteed, our products can be sent out from our company.
