5. Operating Instructions
5.1 Initial Charging
Before first use, fully charge the Empire FRS-001-LI battery. This helps to condition the battery for optimal performance and longevity.
- After installing the battery, place your Cobra two-way radio into its compatible charging cradle or connect it to its designated charger.
- Ensure the charger is connected to a power source.
- Observe the charging indicator on your radio or charger. Charging times may vary, but a full charge typically takes several hours. Refer to your radio's manual for specific charging duration.
- Once fully charged, the indicator light will typically change color or turn off.
5.2 Regular Charging and Usage
- Charge Regularly: For best results, charge the battery regularly, ideally before it is completely depleted.
- Avoid Overcharging: While modern Li-Ion batteries have protection circuits, it is generally good practice to remove the radio from the charger once fully charged if not in use.
- Temperature: Charge the battery at room temperature (10°C to 30°C / 50°F to 86°F) for optimal efficiency and battery health.
6. Maintenance
Proper maintenance extends the life of your Empire FRS-001-LI battery:
- Cleaning: Periodically clean the battery contacts and the radio's contacts with a clean, dry cloth to ensure good electrical connection. Do not use abrasive cleaners or solvents.
- Storage: If storing the battery for an extended period, charge it to approximately 50% capacity and store it in a cool, dry place (e.g., 20°C / 68°F). Avoid extreme temperatures.
- Avoid Deep Discharge: While Li-Ion batteries tolerate deep discharge better than older chemistries, consistently running the battery to 0% can reduce its overall lifespan.
- Disposal: Do not dispose of Li-Ion batteries with household waste. Follow local regulations for proper recycling of electronic waste and batteries.
7. Troubleshooting
If you encounter issues with your Empire FRS-001-LI battery, consider the following:

- Verify the charger is functioning and properly connected to a power source.
- Check for any visible damage to the battery or charger.
- Try cleaning the battery and radio contacts.
- Short Battery Life:
- Ensure the battery is fully charged before use.
