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.
