4.1.3 Fast Charge / discharge condition
Cells shall be charged at constant current of 0.5C to 4.2V with end current of 50mA. Cells shall be
discharged at constant current of 0.5C to 2.75V. Cells are to rest 10 minutes after charge and 20 minutes
after discharge.

Specification
≤ ΩCell shall be measured at 1kHz after charge per
70 m , with PTC
4.1.1.
Cells shall be charged per 4.1.1 and discharged 2500 mAh (Cmin)
per 4.1.2 within 1h after full charge.
Cells shall be charged and discharged per 4.1.3
80% (of Cmin in 2.1)
300 cycles. A cycle is defined as one charge
and one discharge. 301st discharge capacity
shall be measured per 4.1.1 and 4.1.2
4.3 Environmental specification.

Specification
4.3.1
Storage Characteristics
Cells shall be charged per 4.1.1 and stored in a
temperature-controlled environment at 25ºC ±
2ºC for 30 days. After storage, cells shall be
Capacity remaining rate
90% (Cmin in 2.1)
discharged per 4.1.2 to obtain the remaining
capacity*.
4.3.2
High Temperature
Cells shall be charged per 4.1.1 and stored in a No leakage,
temperature-controlled environment at 60ºC for Capacity recovery rate
Storage Test
1 week. After storage, cells shall be discharged 80%
per 4.1.2 and cycled per 4.1.3 for 3 cycles to
obtain recovered capacity*.
4.3.3
Cells are charged per 4.1.1 and stored at 60ºC No leakage, No rust
High Temperature and (95% RH) for 168 hours. After test, cells are Capacity recovery rate
High Humidity Test
discharged per 4.1.2 and cycled per 4.1.3 for 3 80%
cycles to obtain recovered capacity.
* Remaining Capacity : After storage, cells shall be discharged with Std. condition(4.1.2) to measure the remaining capacity.
** Recovery Capacity : After storage, cells shall be discharged with fast discharge condition(4.1.3), and then cells shall be charged with std.
charge condition(4.1.1), and then discharged with Std. condition(4.1.2). This charge / discharge cycle shall be repeated three times to measure
the recovery capacity.
