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. |
