Operating Instructions
Charging the Battery
Always use a charger compatible with Ni-MH batteries. Overcharging or using an incompatible charger can damage the battery and pose a safety risk. The charging time will vary depending on the charger and the battery's discharge level.
Battery Life and Performance
The actual operating time of the battery depends on the radio's power consumption, transmission frequency, and environmental conditions. To maximize battery life:
- Avoid frequent partial discharges; occasional full discharge and recharge cycles can help maintain battery capacity.
- Do not leave the battery on the charger indefinitely after it is fully charged, unless the charger is specifically designed for trickle charging.
Maintenance
Proper care and maintenance will extend the life of your Empire 2-Way Radio Battery.
- Cleaning: Periodically clean the battery contacts with a clean, dry cloth to ensure good connection with the radio and charger.
- Storage: If storing the battery for an extended period, store it in a cool, dry place (ideally between 10°C and 25°C / 50°F and 77°F) with approximately 50% charge. Avoid storing fully charged or fully discharged batteries for long periods.
- Temperature: Do not expose the battery to extreme heat or cold, as this can degrade performance and shorten its lifespan.
