5. Operating (Charging)

For optimal performance and longevity, it is crucial to charge the BP-252 battery correctly.

Initial Charging

For the first 3 charging and discharging cycles, we kindly suggest fully draining the battery before fully charging it. This practice can greatly improve the overall life of the BP-252 battery.

Standard Charging Procedure

1. Connect your compatible ICOM radio (with the BP-252 battery installed) or the BP-252 battery directly to its designated charger.
2. Ensure the charger is connected to a stable power source.
3. Observe the charging indicator on your radio or charger. It will typically show a solid light or change color when charging is complete.
4. Once fully charged, disconnect the battery or radio from the charger.

6. Maintenance

Proper maintenance can extend the life and performance of your BP-252 battery.

• Storage: If storing the battery for an extended period, charge it to approximately 50% capacity and store it in a cool, dry place away from direct sunlight and extreme temperatures.
• Cleaning: Periodically clean the battery contacts with a clean, dry cloth to ensure good connection with the radio and charger.
• Avoid Deep Discharge: While the battery has protection, try to avoid consistently running the battery completely flat before recharging, especially after the initial cycles.
• Temperature: Avoid exposing the battery to extreme hot or cold temperatures, as this can degrade performance and shorten lifespan.

7. Troubleshooting

If you encounter issues with your BP-252 battery, consider the following common solutions:

• Battery Not Charging:
  • Ensure the charger is properly connected to a power source and the battery.
  • Check for any debris or corrosion on the battery and charger contacts and clean them if necessary.
  • Verify that the charger is compatible with the BP-252 battery.
• Short Battery Life:
  • Ensure the battery is fully charged before use.
  • Review the initial charging recommendations (full drain/charge for first 3 cycles).
  • Extreme temperatures can affect battery performance; avoid using or storing in very hot or cold conditions.
  • The battery has a lifespan of over 800 charge cycles. If it has exceeded this, replacement may be necessary.
