7. Maintenance and Storage
7.1 General Maintenance
- Keep the battery terminals clean and free from dirt or debris.
- Periodically inspect the battery for any physical damage.
- Avoid exposing the battery to extreme temperatures or moisture.
7.2 Storage
When not in use for extended periods, store the battery in a cool, dry place, ideally at room temperature. Avoid storing it in direct sunlight or in environments where temperatures can exceed 60°C (140°F).
