I have a set of rechargeable batteries that will not charge in the BP60 belt pack or in the HHM60 microphone. It’s not the batteries, as they are new.

When replacing the Ni-MH batteries in the BP60 or in the HHM60, it is necessary to remove a 1/2-inch of insulation from the negative end of the battery. This is to prevent accidental charging of alkaline batteries in the BP60 or in the HHM60.
