5. Operating (Charging and Usage)
5.1 Initial Charge
For optimal performance, fully charge the battery before its first use. Ni-MH batteries benefit from a full charge and discharge cycle initially.

- Ensure the charger's indicator light confirms charging is in progress.
- Allow the battery to charge completely. Charging times may vary depending on the charger and the battery's discharge level. Refer to your radio's or charger's manual for specific charging durations.
- Avoid overcharging for extended periods once the battery is full, though modern chargers typically have overcharge protection.
5.3 Usage
Once charged, the battery will power your radio. Monitor your radio's battery indicator to determine when recharging is necessary. For best battery life, avoid completely draining the battery frequently.
