Built-in protective circuit

The protective circuit built into the Panasonic 18650 battery with a nipple top could prevent overcharge issues—the perfect friend for your dive torch.

(The reason why we don’t recommend a flat-top version battery is that a flat-top one doesn’t have a protective circuit, and the battery can be damaged by overcharging or over-discharging)

Storing the 18650

Storing Conditions less than 1 month -20 ~ +50°C Percentage of recoverable capacity 80%*
less than three months -20 ~ +40°C
less than one year -20 ~ +20°C

*= (Discharging time after storage / Initial discharging time) *100

The discharge current of 0.65A measures the discharging time until 2.5V of end voltage after the battery is fully charged at 25°C.

It’s recommended to use a Battery Storage Box for your 18650
