You want to help keep your 2-way radio working problem free and out of the repair department? SIMPLE: Clean your battery contacts, both on the radio and charger, with a pencil eraser. This will clean off the day-to-day grime and film, allowing your battery to make better contact with the radio and charger. (Refrain from using any alcohol or cleaners, which may cause a film to develop.) Try this simple tip, and enjoy a fully charged battery and possible added battery life.
