Warm Tips
If the model you need is not on the list or you are not sure if it is suitable for your radio,
please feel free to let us know,and we will offer you the most suitable items.

[Note] Keep away from the fire！
Protect the environment,please don't throw it in the trash!
You can dispose of any battery at any RBRC-affiliated shop. RBRC (Rechargeable Battery Recycling Corporation) has members in every major city in the United States. There is no charge for disposing of batteries there

Spare batteries:
Did you know that you can remove the battery from the radio and charge it by itself? Therefore, we recommend that you have a spare battery for each radio.
No matter when and where, there is always a fully charged battery in the charger. You never have to worry about the radio breaking down on the second shift, or accidentally forgetting to put the radio back in the charger at the end of the day.
