Characteristic of custom 2600mAh Li-ion battery

Without special instructions, the following tests should be done under the condition of : temperature(23℃±3℃), atmospheric pressure (86KPa～106KPa), relative humidity (45%～85%), and the tests should be done within two weeks after receiving the products.

the definitions of some nomenclatures of this specification

standard Charge: Charge with current 0.2C5A to limit charge voltage under the condition of23℃±3℃ surrounding temperature, then change to charge with constant voltage till the current less than or equal to 0.02C5A.

Electrical Characteristic for power tool rechargeable Li-ion battery supplier

NO.	Item	Standard	Test Method
1	Discharge rate capabilities	A）1 C5A ≥100% B）10 C5A ≥95% C）15 C5A ≥90%	Standard charged under the condition of normal atmospheric pressure and the environmental temperature of 23℃±3℃ and45%～85%RH, then rest for 30mins and discharge at1C5A、5 C5A、10 C5A to the discharge cut-off voltage respectively. Charge/discharge cycle can be conducted for 3times before meeting the Standards（the same below）
2	capacity retention and recovery	Residualcapacity≥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 C5A to 2.75Vmeasuring residual capacity; Then standard charge/discharge measure recoverable capacity.
3	Low Temperature Performance	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 0.2C5A down to the end-of-discharge voltage 2.75V.
4	Cycle Life	≥300cycles	Charge: The cell shall be charged in accordance with RapidCharge condition. rest for 10mins.Discharge: 10C5A discharge to 2.75V, one cycle is finished, then rest for 30mins. Then repeat above steps, when capacity is less than 80% of initial capacity, the battery life is over.

Safety Characteristic of e-bike cylindrical power lithium-ion batteries

NO.	Item	Standard	Test Method
1	Overcharge	No fire、No explosion	After standard charge, rest for 10mins; then charge at constant current of 3C5A to 10V.(or charge at 3C5A for 90mins).
2	Forced discharge	No fire、No explosion	The battery to be discharged with standard discharging condition, Inverse charge current =1C5A；time: ≥ 90mins
3	Short Circuit test	No fire、 No explosion	The battery to be fully charged with standard charging condition, and short the positive and negative terminals with wire resistance ≤50mΩ.Tests are to be conducted at 23℃±3℃ and at 55℃ ±5℃, keep 24h or case temperature decline to 20% of the max temperature ,test is over.
4	Crush test	No fire、No explosion	A battery is crushed between two flat surfaces. The applied force is 13 kN±1kN by hydrocylinder, Once the maximum pressure has been obtained or voltage decrease to 1/3 of nominal voltage sharply, then release pressure.
