3. Operating Guidelines
To maximize the life and performance of your Energizer D batteries and ensure safety, please adhere to the following guidelines:
- Use Correct Type: Always use the size and type of battery specified by the device manufacturer.
- Replace All Batteries: When replacing batteries in a device, replace all of them at the same time. Do not mix old and new batteries, or batteries of different types or brands.
- Remove from Unused Devices: If a device will not be used for an extended period, remove the batteries to prevent potential leakage and damage.
- Prompt Removal of Used Batteries: Remove depleted batteries from devices immediately to avoid leakage and corrosion.
4. Maintenance and Storage
Proper care and storage will help maintain battery performance and extend their shelf life.
- Storage Conditions: Store unused Energizer D batteries in their original packaging in a cool, dry place at normal room temperature (e.g., 20-25°C or 68-77°F).
- Avoid Extremes: Do not store batteries in direct sunlight, areas of high temperature (e.g., near heaters, in a hot car), or high humidity.
- Prevent Short Circuits: Avoid storing batteries loosely in a pocket, purse, or drawer with metal objects like coins, paper clips, or keys. This can cause a short circuit, leading to heat generation or leakage.
- Clean Contacts: If necessary, clean the battery contacts in your device and on the batteries themselves by gently rubbing with a clean pencil eraser or a rough cloth.
- Disposal: Dispose of used batteries responsibly. Do not dispose of batteries in fire, as they may explode or leak. Follow local regulations for battery recycling and disposal.

5. Troubleshooting
If your device is not functioning correctly after installing new Energizer D batteries, consider the following common issues:
- Incorrect Polarity: Double-check that the batteries are inserted with the correct positive (+) and negative (-) terminals aligned with the device's markings.
- Dirty Contacts: Inspect the battery contacts in both the device and on the batteries. Clean any dirt, dust, or corrosion using a clean, dry cloth or a pencil eraser.
- Expired or Depleted Batteries: Ensure the batteries are fresh and not past their expiration date. Although Energizer D batteries have a long shelf life, prolonged storage or previous use can affect their charge.
- Device Malfunction: If the batteries are correctly installed and fresh, the issue might be with the device itself. Test the device with another set of known-good batteries or consult the device's instruction manual.
- Mixing Battery Types: Confirm that you are not mixing different types or brands of batteries within the same device, as this can impair performance.
