Charge Voltage

8.4V(single cell 4.2V)

3

Nominal Voltage

7.4V

The average value of voltage during the discharge period (with standard charge and discharge). When shipping, the voltage without load is between 7.2V and 7.7V.

Nominal Capacity

Typ:4600mAh@ 0.2C
Discharge
Min:4500mAh

Nominal Capacity refer to the capacity of 0.2C discharge to 5.6V cut-off voltage, after charging with standard method.

5

Cycle Life

300 Times

One cycle refer to one charge period and then one discharge period.
Test condition:
Charge:0.2C to 8.4V
Discharge: 0.2C to 5.6V
The cycle life is the cycle times when the discharge capacity is about 75% of the rated capacity.

Operating Temperature

Discharge: -10°C~ +45°C 
Charge: 0°C~ +45°C

Cells must be stored at 7.2V~7.8V. Over long storage periods cells should be cycled every 90 days. The method is to do a charge-discharge

cycle with standard method, then charge to 7.2V~7.8V.
