Maintenance and Storage
Proper maintenance and storage will extend the lifespan of your Li-ion batteries.
- Regular Charging: Do not allow batteries to fully discharge for extended periods. Recharge them after each use.
- Long-Term Storage: For storage longer than a few days, charge the batteries to approximately 50-60% capacity. Storing fully charged or fully discharged can degrade battery health.
- Temperature: Store in a cool, dry environment, ideally between 5°C and 20°C (41°F and 68°F). Avoid extreme heat or cold.
- Inspection: Periodically inspect batteries for any signs of damage, swelling, or leakage. Discontinue use if any issues are observed.
- Cleaning: Keep battery terminals clean and free of debris. Use a dry cloth to wipe them if necessary.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Battery not charging. | Loose connection, faulty USB cable/adapter, or damaged battery. | Ensure all connections are secure. Try a different USB port or power adapter. If the issue persists, the cable or battery may be faulty. |
| Short run-time. | Battery not fully charged, aged battery, or high power demand from device. | Ensure battery is fully charged before use. Li-ion batteries degrade over time; consider replacement if significantly old. |
| Battery gets hot during use/charging. | Overload, internal short, or faulty charger. | Discontinue use/charging immediately. Allow to cool. If overheating persists, the battery or charger may be defective. Do not use a swollen battery. |
| Battery does not fit in device. | Incorrect battery model or slight size variation. | Verify compatibility with your device's specifications. Some devices may have tight tolerances. |
