Frequently Asked Questions

How long should I charge my two way radio battery?

As always, it depends on the type of battery. Nicad, NiMH and Li-Ion all have different charging methods. Generally though, it should only take two hours on a rapid charger and 4-6 hours on a standard charger. Some specialized chargers take longer, such as charger-conditioners.

What is the difference between regular batteries and intrinsically safe radio batteries?

Intrinsically safe batteries are batteries that are designed to work in dangerous environments where batteries could accidentally set off explosive gasses or combustible material. If you need to communicate around oil or propane refineries, textile factories, munitions, etc. then you must use intrinsically safe (or IS) batteries.

What do I do with my old batteries?

You can dispose of any batteries at any RBRC affiliated store. The RBRC (Rechargeable Battery Recycling Corporation) has members in every major city in the United States. There is no charge to drop your batteries off there. Home Depot and Radio Shack are two of its predominant members.
