Operating Instructions
Once installed, the battery operates like the original. For optimal performance:
- First Use: Fully charge the battery before its initial use. This helps calibrate the battery and ensures maximum capacity.
- Regular Charging: For cordless phones, return the handset to its charging base when not in use to keep the battery charged.
- Avoid Deep Discharge: While NiMH batteries are less prone to memory effect than NiCd, avoiding frequent deep discharges can help prolong battery life.
Maintenance
Proper maintenance can extend the lifespan of your battery:
- Storage: If storing the battery for an extended period, charge it to about 50% and store it in a cool, dry place. Recharge every 3-6 months to prevent over-discharge.
- Cleaning: Keep battery contacts clean. Use a dry cloth to wipe away any dust or debris.
- Temperature: Avoid exposing the battery to extreme temperatures, both hot and cold, as this can degrade performance and lifespan.
Troubleshooting
If you encounter issues with your replacement battery, consider the following:
- Battery Not Charging:
- Ensure the battery connector is securely plugged into the device.
- Verify the device's charging base or power adapter is functioning correctly and connected to a power source.
- Clean the charging contacts on both the device and the charging base.
- Short Battery Life:
- Ensure the battery has been fully charged before use.
- Check if the device itself is consuming excessive power due to settings or age.
- If the battery is new, it might require a few charge/discharge cycles to reach full capacity.
- Device Not Powering On:
- Confirm the battery is correctly installed and fully charged.
- Ensure the device itself is not faulty. Try powering it on with another known-good battery if available.
