Perform a visual inspection prior to installation. Cells are shipped half-charged; no special activation routine is required. Always match the charger specifications with the battery before charging.
Avoid using fast chargers on standard, non-fast-charge series. Doing so causes electrode damage, capacity degradation, and irreversible electrochemical changes.
Store batteries charged to 50%-70% of capacity in a cool environment with ambient temperatures strictly below 25ºC.
Avoid overcharging and overdischarging. Under high temperatures (e.g. summer), do not expose the pack to direct sunlight, and do not charge it immediately after use without cooling down first.
