Solution
Disconnect the DC coupler from the compact power adapter when charging a battery pack.
We recommend charging the battery pack in temperatures between 10 ℃ and 30 ℃ (50 ℉ and 86 ℉). The charging time will vary depending on the surrounding temperature and the battery's initial charge condition.
Charged battery packs continue to discharge naturally. Therefore, charge them on the day of use, or the day before, to ensure a full charge.
