4. Maintenance
Proper maintenance ensures the longevity and reliability of your battery.
4.1 Charging
- Use a charger specifically designed for 12V sealed lead-acid batteries.
- Do not overcharge or undercharge the battery, as both can reduce its lifespan.
- Recommended float charge voltage: 13.5 to 13.8 volts at 20°C (68°F).
- Recommended cyclic charge voltage: 14.4 to 15.0 volts at 20°C (68°F).
- The maximum initial charging current should not exceed 0.69A (0.3CA).
4.2 Storage
- Store the battery in a cool, dry, and well-ventilated area.
- Ensure the battery is fully charged before storage.
- For extended storage, recharge the battery every 3-6 months to prevent sulfation and capacity loss.
4.3 Cleaning

5. Troubleshooting
This section addresses common issues you might encounter with your battery.
| Problem | Possible Cause | Solution |
|---|---|---|
| Battery not holding charge | Undercharging, overcharging, sulfation, end of life. |
|
| Device not powering on | Low battery charge, loose connections, incorrect polarity. |
|
| Battery casing is swollen or leaking | Overcharging, internal damage, excessive heat. | Immediately discontinue use. This indicates a severe fault. Safely disconnect and replace the battery. Do not attempt to charge or use a swollen/leaking battery. |
If you experience issues not covered here, or if troubleshooting steps do not resolve the problem, contact customer support.
