6. Maintenance
6.1 Cleaning
Ensure the charger is unplugged before cleaning. Use a soft, dry cloth to wipe the exterior of the charger. Do not use liquid cleaners or solvents.
6.2 Storage
Store the charger and batteries in a cool, dry place away from direct sunlight and extreme temperatures. For long-term storage, it is recommended to store Ni-MH batteries with a partial charge (around 50%).
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger LEDs do not light up. | Charger not plugged in correctly; power outlet issue; defective charger. | Ensure the charger is securely plugged into a working outlet. Try a different outlet. If the issue persists, the charger may be defective. |
| Batteries are not charging (LEDs turn off immediately or do not light). | Incorrect battery type (non-rechargeable); incorrect polarity; defective battery; short-circuited battery. | Verify batteries are Ni-MH/Ni-Cd rechargeable type. Check battery polarity. Remove and reinsert batteries. Try charging a different battery. If a battery is defective, it will not charge. |
| Batteries do not hold a charge for long after charging. | Batteries are old or nearing end of life; high drain device usage. | Rechargeable batteries have a limited lifespan. Consider replacing old batteries. Ensure the device using the batteries is not excessively draining them. |
