Maintenance and Storage
- Charging: Recharge batteries when they show signs of depletion. Avoid overcharging or deep discharging, as this can reduce battery life.
- Storage: Store batteries in a cool, dry place away from direct sunlight and extreme temperatures. Keep batteries away from fire or explosion hazards.
- Long-Term Storage: For extended storage, it is advisable to store batteries with a partial charge (around 50%).
- Cleaning: Keep battery contacts clean. Use a dry cloth to wipe off any dirt or corrosion.
Troubleshooting
If your rechargeable batteries are not performing as expected, consider the following:
- Battery Not Charging: Ensure the charger is functioning correctly and the batteries are inserted with correct polarity. Try a different charger if available.
- Shortened Run Time: This may indicate the batteries are nearing the end of their life cycle (after many recharges) or were not fully charged. Ensure a full charge cycle.
- Device Not Powering On: Verify correct battery insertion and that the device itself is functional. Check if the batteries are fully charged.
