1. New Battery Care: Visual inspection before install. Batteries are usually shipped at 50% charge; no special activation needed.
2. Fast Charging: Avoid fast-charge devices for non-fast-charge series to prevent capacity loss and electrode damage.
3. Storage: Store at 50%-70% charge in temperatures below 25ºC when not in use for long periods.
4. Charging Sequence: Connect charger to device first, then to power supply to avoid short circuits.
5. Temperature Control: Avoid direct sunlight or high-temperature charging in summer. Low-temperature use may temporarily reduce range.
