We recommend charging the battery pack in temperatures between 10 °C and 30 °C (50 °F and 86 °F). Outside the temperature range of 0 °C to 40 °C (32 °F to 104 °F), the charging will not start.

If you connect a faulty power adapter or battery pack, the CHARGE indicator flashes rapidly (approx. twice per second) and the charging stops.

The CHARGE indicator also serves as a rough estimate of the battery charge status.

Continuously on: Battery fully charged.

Flashes rapidly (approx. twice per second): Battery over 50% charged.

Flashes slowly (approx. once per second): Battery less than 50% charged.

We recommend that you prepare battery packs 2 to 3 times longer than you think you might need.

The charging time will vary depending on the surrounding temperature and the battery pack’s initial charge condition.

In cold surroundings the usable time of the battery pack will decrease.
