Electrical Characteristic  for Cylindrical Rechargeable Electric vehicle li-ion Battery

NO. Item Standard Test Method
1 Discharge rate capabilities A）1 C5A ≥97% B）5 C5A ≥95% 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 2.50Vmeasuring 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 0.2C5A down to the end-of-discharge voltage 2.750V.
4 Cycle Life Charge: The cell shall be charged in accordance with RapidCharge condition. rest for 10mins.Discharge : 5C5A 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.

Warranty Period & Product Liability  for car 18650 battery

Warranty period of this product is 12 months from manufacturing code. JIANGSU SUNPOWER CO., LTD. is not responsible for the troubles caused by mishandling of the battery which is against the instructions in 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.

Storage
