Test Method

1

Discharge rate capabilities

Standard charged, then rest for 30mins and discharge at 0.2C、1C、3C、5 C and 2.5V cut-off

2

capacity retention and recovery

Residual capacity≥94% Recoverablecapacity≥*98%

Standard charged under the condition of normal atmospheric pressure and the environmental temperature of 23℃±3℃, Stored for 28 days, then discharge at 0.2 C to 2.75V measuring residual capacity; Then standard charge/discharge measure recoverable capacity.

3

Low TemperaturePerformance

discharge capacity≥85% rated capacityno distortion and no rupture

The cell shall be charged in accordance with the standard charge. Then stored in the temperature of -10℃±1℃ for4h, Discharge at the constant current of 0.2C down to the end-of-discharge voltage 2.750V.

4

Cycle Life

1C charged the cell to 4.2V, then change to charge with constant voltage till the current less than or equal to 0.04C, rest for 30mins; 10A discharge to 2.75V, one cycle is finished, rest for 30mins. Then repeat above steps, when capacity is less than 70% of initial capacity, the battery life is over.

Ship

The cells might be damaged during shipping by shock. If any abnormal features of the cells are found such as deformation of the cell package, smelling of an electrolyte, an electrolyte leakage and others, the cells shall never be used any more. The Cells with a smell of the electrolyte or a leakage shall be placed away from fire to avoid firing.

Storageof power tool 18650 battery

The cell shall be stored at the environmental condition of -20℃- 45℃ and 65%±20% RH. The voltage for long time storage shall be 3.5V-3.7V range. If the cell has to be storied for a long time (Over 3 months), the environmental condition should be: Temperature: 23℃±3℃Humidity: 65%±20%RH;please activate the battery once every 3 months according to the following method: Charge with current 0.2C until the voltage achieve to 3.7V.
