- Cleaning: Use a soft, dry cloth to clean the battery casing. Do not use harsh chemicals or abrasive cleaners.
- Terminal Inspection: Periodically check the battery terminals for corrosion or loose connections. Clean if necessary.
- Avoid Deep Discharge: While the BMS protects against over-discharge, try to avoid consistently running the battery completely flat to prolong its lifespan.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Battery not charging | Charger not connected properly; Faulty charger; Battery temperature too high/low; Battery fault. | Ensure charger is securely plugged into outlet and battery. Try another outlet. Allow battery to reach room temperature. Contact support if problem persists. |
| Battery not powering device | Battery not installed correctly; Low battery charge; Loose connections; Device fault. | Ensure battery is securely locked in place. Check battery charge level and recharge if necessary. Verify all cables are firmly connected. Test battery with another compatible device if possible. |
| Reduced battery range/capacity | Aging battery; Frequent deep discharges; Extreme operating temperatures. | Ensure proper charging habits. Avoid extreme temperatures during operation and storage. Battery capacity naturally degrades over time. |
| Unusual heat from battery | Overload; Internal short circuit; Faulty charger. | Immediately disconnect the battery from the device and charger. Allow it to cool down in a safe, non-flammable area. Do not use if excessive heat persists. Contact support. |
