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.

Easy process. Steve was very nice and knowledgeable with battery settings to my Harris Xg100p and was able to walk me through the setting to get the best battery performance. The battery that was bought is an extremely nice looking battery and performs as designed. I came to Steve after an eBay seller overcharged me for OEM Harris battery, and that battery was advertised as new but simply just didn't perform at all. Anybody looking at Battery Universe can be assured that they will be well taken care of, and the battery will perform as advertised. Gary P.

Site easy to use , I was contacted prior to shipment that 1 item was back ordered until lat the next month and wanted to find out if I still wanted what they had in stock or wanted to cancel. When I told them I would like what they had. I was asked if I wanted a refund on the back ordered item or if I wanted to just wait and have it shipped when it came in . I requested to have them ship it to me when it came in. This is great customer service!!!
