6. Verify that the battery is firmly seated and does not wobble.

6. Operating

Initial Charging:

For optimal performance, fully charge the battery before its first use. NiMH batteries often benefit from a full charge/discharge cycle initially.

Charging Procedure:

1. Connect your Yaesu radio (with the BCXY battery installed) to its compatible charger.
2. Ensure the charger is plugged into a working power outlet.
3. Observe the charging indicator on your radio or charger. Refer to your radio's manual for specific charging light indications.
4. Allow the battery to charge completely. Charging times may vary depending on the charger and the battery's discharge level.
5. Once fully charged, disconnect the radio from the charger.

Usage:

Operate your radio as usual. The battery provides 12.0V power with a capacity of 1000mAh. Battery life will vary based on radio usage, transmit power, and environmental conditions.

7. Maintenance

Battery Care:

• Avoid Deep Discharge: While NiMH batteries are less prone to memory effect than older NiCd batteries, avoiding frequent deep discharges can help prolong their lifespan.
• Regular Charging: Charge the battery regularly, but avoid overcharging for extended periods (e.g., leaving it on a charger for weeks).
• Clean Contacts: Periodically clean the battery terminals and radio contacts with a dry, clean cloth to ensure good electrical connection.

Storage:

• If storing the battery for an extended period, charge it to approximately 50-70% capacity.
• Store the battery in a cool, dry place, away from direct sunlight and extreme temperatures.
• Avoid storing the battery in environments with high humidity.

8. Troubleshooting

Battery Not Charging:

• Check Connections: Ensure the battery is properly seated in the radio and the charger is securely plugged in.
• Verify Charger Function: Test the charger with another known-good battery or device if possible.
• Clean Contacts: Dirty battery or radio contacts can prevent charging. Clean them as described in the Maintenance section.
• Temperature: Ensure the battery is within the recommended charging temperature range (typically 0°C to 45°C or 32°F to 113°F).

Short Battery Life:

• Full Charge: Ensure the battery is being fully charged each time.
• Radio Settings: High transmit power settings or continuous transmission will deplete the battery faster.
• Battery Age: All rechargeable batteries degrade over time. If the battery is old, its capacity may have diminished.
• Environmental Factors: Extreme cold can temporarily reduce battery performance.

Battery Not Fitting:

• Verify Model: Double-check that your radio model is listed as compatible with the BCXY CS-FNB17TW battery.
• Orientation: Ensure the battery is oriented correctly before attempting to insert it.
