4. Maintenance and Safety Precautions
Proper handling and storage are essential for the longevity and safe operation of these batteries. Adhere to the following guidelines:
- Storage: Store batteries in their original packaging in a cool, dry place, away from direct sunlight and extreme temperatures. Keep them out of reach of children and pets.

- Disposal: Dispose of used batteries responsibly according to local regulations. Do not dispose of batteries in household waste or by incineration.
- Leakage: In case of battery leakage, avoid contact with skin and eyes. If contact occurs, rinse immediately with plenty of water and seek medical attention.
- Ingestion Hazard: Button cell batteries can be swallowed. Keep new and used batteries out of reach of children. If swallowed, seek immediate medical attention.

5. Troubleshooting
If your device is not functioning after battery installation, consider the following:
- Incorrect Polarity: Double-check that the battery is inserted with the correct positive (+) and negative (-) orientation.
- Poor Contact: Ensure the battery is making firm contact with the device's terminals. Gently clean the terminals if there is any visible corrosion or dirt.
- Depleted Battery: Although new, a battery might be depleted if it was stored improperly or is past its shelf life. Try a different battery from the pack.
- Device Malfunction: If the issue persists after trying a new battery and verifying installation, the problem may lie with the device itself, not the battery. Consult your device's manual or manufacturer.
