| Electrical characteristics | Open circuit voltage (at 25°C) | ≥3.65V |
| Nominal capacity | 3500mAh | |
| (At +25°C, the battery is discharged at a continuous current of 6mA until the voltage reaches a cut-off voltage of 2.0V. The capacity can vary at different temperatures, discharge current or cut-off voltage. ) | ||
| Maximum continuous current | 600mA | |
| (At +25°C, 2.0V cut-off, battery discharged for a minimum of 50% of nominal capacity. ) | ||
| Maximum pulse discharge current | 1200mA | |
| (At +25°C, 2.0V cut-off, battery discharged for a minimum of 50% of nominal capacity with max pulse for 3 seconds after 27 seconds break. The discharged capacity may vary according to the pulse characteristics, the temperature, and the cell’s previous history. Fitting the cell with a capacitor may be recommended in severe conditions, consult HCB.) | ||
| Storage (recommended) | ≤+30°C | |
| (For more severe conditions, consult HCB) | ≤75%RH | |
| Operating temperature range | -55°C~+85°C | |
| (Operation above ambient temperature may lead to reduced capacity and lower voltage readings at the beginning of pulses, consult HCB.) | ||
