1. New Battery Maintenance: Visual inspection before installation. Batteries are usually half-charged from the factory; no special activation is needed.
2. Fast Charging: Not recommended for non-fast-charge series as it may cause irreversible electrode changes and capacity loss.
3. Storage: Store at 50%-70% charge in temperatures below 25ºC for long-term storage.
4. Daily Use: Avoid overcharging and overdischarging. In summer, avoid direct sun exposure and ensure heat dissipation before charging.
