4. Operating (Usage)

5. Maintenance
Proper maintenance can extend the lifespan of your battery:

If you encounter issues with your new Peakbatt BL-166 battery, consider the following:
- Device Not Powering On: Ensure the battery is correctly seated in its compartment and fully charged. Verify that the device itself is functioning correctly.
- Battery Not Charging: Check the charging cable and adapter for damage. Try charging with a different compatible charger. Ensure the charging port on your device is clean.
- Rapid Battery Drain: This could indicate high background app usage or device settings. Review your device's power management settings. If the issue persists, the battery may be faulty.
- Overheating: If the battery or device becomes excessively hot during charging or use, immediately disconnect the charger and power off the device. Do not use the battery if it shows signs of swelling or damage.
