5. Maintenance and Care
Proper maintenance extends the life and performance of your rechargeable batteries:
- Regular Charging: Recharge batteries when they are depleted. Avoid completely draining them repeatedly, as this can shorten their overall lifespan.

- Disposal: Do not dispose of rechargeable batteries in household waste. Recycle them at designated battery recycling centers.
6. Troubleshooting
If you encounter issues with your Energizer Recharge batteries, consider the following:
- Batteries Not Charging:
- Ensure the charger is properly plugged into a working outlet.
- Verify batteries are inserted with correct polarity.
- Check for dirt or corrosion on battery and charger contacts; clean if necessary.
- Some chargers indicate a 'bad battery' with a specific light pattern or sound. If this occurs, the battery may have reached the end of its life or be damaged.
- Short Operating Time:
- Ensure batteries are fully charged before use.
- Battery capacity naturally diminishes over many charge cycles. If operating time is consistently short, batteries may need replacement.
- High-drain devices consume power more quickly.
- Device Not Powering On:
- Confirm batteries are fully charged.
- Check device's battery compartment for proper insertion and clean contacts.
