5. Maintenance and Storage
To maximize battery life and ensure safe storage:
- Store unused batteries in their original packaging in a cool, dry place.
- Avoid storing batteries in direct sunlight or near heat sources.
- The recommended storage temperature range is -20°C to 35°C (-4°F to 95°F).
- Do not store batteries loose in a drawer or container with metal objects (like coins or keys), as this can cause short circuits.
- Check the freshness date on the battery before use to ensure optimal performance.

6. Troubleshooting
If your device is not functioning correctly with new Duracell PROCELL C12 batteries, consider the following:
- Device Not Powering On:
- Verify that the batteries are inserted with the correct polarity (+/-).
- Ensure the battery contacts in the device are clean and free of corrosion. Gently clean with a pencil eraser or cotton swab if necessary.
- Test the device with another set of new batteries to rule out a device malfunction.
- Short Battery Life:
- Confirm the device is compatible with alkaline batteries and not designed for rechargeable or other battery types.
- Ensure the device is not experiencing an internal short circuit or excessive power draw.
- Check the battery's freshness date.
- Battery Leakage:
- Remove the leaking battery immediately, wearing protective gloves.
- Clean the battery compartment thoroughly with a cotton swab dipped in vinegar (for alkaline leaks) to neutralize the residue.
- Dispose of the leaking battery according to local regulations.
