8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Battery not charging | Incorrect battery insertion, faulty charger, damaged battery, insufficient power supply. | Ensure correct polarity. Try a different charger or power source. Check for visible battery damage. If the charger shows a red error light, the battery might be faulty or too hot/cold. |
| Device not powering on with charged batteries | Incorrect battery insertion, device malfunction, battery not fully charged, incompatible device. | Verify battery polarity. Test batteries in another device. Ensure batteries are fully charged. Confirm device compatibility with 1.5V lithium-ion batteries. |
| Reduced battery life | High-drain device, aging battery, extreme operating temperatures, frequent deep discharge. | Battery life varies by device and usage. Ensure proper charging and storage. Consider replacing batteries if they have reached their end-of-life cycle (approx. 2000 cycles). |
