Usage and Maintenance: 1. Connect the battery first, then plug into AC power. After full charge, disconnect AC power, then the battery. 2. LED turns green when fully charged, then charge for 2-3 additional hours. 3. Avoid completely draining the battery before charging, as this can damage the battery. 4. Perform a deep discharge every 3 months to activate long-term dormant materials. 5. If unused for 2-3 months, charge the battery before use and ensure it's not damaged. 6. Use the charger in a dry place and disconnect power when not in use. 7. Confirm the charger is suitable for your lithium-ion battery, not LiFePO4.
