6. Maintenance
Proper maintenance will extend the lifespan and performance of your Jectse EN-EL3E batteries:
- Cleaning: Use the provided microfiber cleaning cloth to gently wipe the battery contacts and the battery compartment of your camera to ensure good electrical connection. Avoid using harsh chemicals or abrasive materials.
- Storage: When not in use for extended periods, store the batteries in a cool, dry place away from direct sunlight and extreme temperatures. It is recommended to store them with a partial charge (around 50%) rather than fully charged or fully depleted.
- Avoid Physical Damage: Do not drop, puncture, or disassemble the batteries. Physical damage can lead to internal short circuits or other hazards.
7. Troubleshooting
If you encounter issues with your Jectse EN-EL3E batteries, consider the following:
- Battery Not Charging: Ensure the charger is properly connected to a power source and the battery. Check if the charger's indicator light shows charging status. Try cleaning the battery contacts.
- Camera Not Powering On: Verify the battery is correctly inserted into the camera compartment. Ensure the battery has sufficient charge. If the issue persists, try another fully charged battery if available.
- Shortened Battery Life: This can be normal over time due to battery degradation. Ensure you are not operating the camera in extremely cold conditions, which can temporarily reduce battery performance.
