6. Maintenance
- Storage: Store batteries in a cool, dry place away from direct sunlight and extreme temperatures. Keep them in the charger or a battery case when not in use to prevent short circuits.
- Cleaning: Use a dry, soft cloth to clean the batteries and charger terminals if necessary. Do not use liquids or abrasive cleaners.
- Disposal: Do not dispose of lithium batteries in household waste. Follow local regulations for proper recycling of rechargeable batteries.
- Long-Term Storage: If storing batteries for an extended period, charge them to approximately 50-70% capacity. Recharge them every 3-6 months to maintain their health.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Battery not charging (Red light flashing or no light) | Incorrect battery insertion, faulty cable/power source, battery deeply discharged. | Ensure correct polarity. Try a different USB cable or power adapter. If battery is at 0V, the charger may not detect it; contact support if issues persist. |
| Device shows "low battery" immediately after inserting charged batteries | Device incompatibility, battery not fully charged, or device requires higher current than supplied. | Ensure batteries are fully charged. Verify device compatibility with 1.5V lithium batteries. Some devices may have specific battery requirements. |
| Batteries drain quickly | High-drain device, extreme temperatures, or battery degradation. | These batteries are designed for high-drain devices. Ensure optimal operating temperature. If batteries are old and have completed many cycles, their capacity may naturally decrease. |
