I thought these were batteries that could be charged while i used my radio. The picture is true, but it makes it look like it is a battery charger. They aren't. They must be in the radio to be charged. Unfortunately, the batteries don't last all day if you use them all day. We are communicating in a campground and i have to switch radios at about 4pm. We ended up sending these back and buying extra radios. Motorola, you need to make a BATTERY charger so i can charge the battery and switch when needed.
