Choosing a Battery

Capacity (mAh): Higher capacity may give longer runtime at the same load; it does not mean higher current capability.

Continuous Discharge (CDR): Match the confirmed CDR to your device’s current demand. Max pulse is not a continuous-use rating.

Key Safety Checks

• Check battery size, voltage, terminal type and protection requirements before use.
• Use a compatible charger and follow the manufacturer’s charging and discharge limits.
• Carry cells individually in protective cases, away from keys and coins, to help prevent short circuits.
• Stop using cells with damaged wraps, leakage or unusual heat; arrange safe recycling where appropriate.
