To ensure optimal performance and longevity of your lithium-ion (Li-ion) battery, consider these maintenance tips:
1. Avoid extreme temperatures: Keep your Li-ion battery within a temperature range of 0°C to 45°C (32°F to 113°F) to prevent damage.
2. Partial discharge: Avoid fully draining your battery frequently. Instead, aim for partial discharges to around 20-80% capacity.
3. Store at partial charge: If storing for an extended period, keep the battery charged at around 50% capacity in a cool, dry place.
4. Regular use: Use your Li-ion battery regularly. If not in use for an extended period, ensure to recharge it periodically.
5. Use original chargers: Always use chargers designed specifically for your Li-ion battery to avoid damage.
6. Avoid overcharging: Remove the battery from the charger once it reaches full capacity to prevent overcharging.
7. Monitor for swelling: If you notice any swelling or unusual behavior, stop using the battery immediately and replace it if necessary.
