Testing method and determinant standard

1

Charge

Performance

The battery can be charged when using the original charger. The standard charge mode :under the temperature of 20±5℃,charge the battery with the current of0.2Cuntil the voltage reaches up to 4.2V,then charge with constant voltage until the charge current ≤0.01C, then stop charging.

2

Discharge

Performance

When connecting with load, the battery can supply power. Charge the battery with standard charge mode, then rest for 0.5h, then discharge with 0.5C until the voltage is 3.0V, and the discharge time is required ≥120min

3

Cycle

Performance

Under the temperature of 20±5℃,charge the battery with0.2C, when the voltage reaches up to 4.2V charge with constant voltage until the charge current≤ 10mA, then stop charging, then rest for 0.5h, then discharge with 0.5C to3.0V. Cycle with the above mode, the test shall be terminated when Discharging Capacity ＜80% of Initial Capacity in three consecutive cycles. The cycle life is required≥300 times.

4

Charged Storage

Characteristics

Charge the battery with0.2C, then shift to charge with constant voltage until thevoltage reaches up to 4.2V, when the charge current ≤0.01Cstop charging;rest under the temperature of 20±5℃for 28 days then discharge with 0.5C to3.0V. The discharge time is required ≥1.6h.

5

Storage

Characteristics

Charge the battery ,which is new manufactured shorter than 3 months, with 0.2C until the capacity reaches to 40~50%, after resting for 6 months under the temperature of 20±5℃and the humidity of 45～75%, then charge with0.2Cto 4.2V then shift to charge with constant voltage, after full-charge rest for 0.5h,then discharge with 0.5C to 3.0V. The discharge time required ≥1.6 h.
