1. New Battery Care: Visual inspection before installation. Factory half-charge is normal; no special activation required.
2. Charging Logic: For non-fast-charge series, avoid high-speed chargers to prevent capacity loss and irreversible electrode changes.
3. Long-term Storage: Maintain 50%-70% charge and store below 25ºC.
4. Safety Protocol: Connect charger to vehicle first, then power supply. Ensure ventilation and avoid flammable surfaces.
5. Temperature Control: Avoid direct sun exposure in summer. Do not charge immediately after use without heat dissipation.
