Two-way radio batteries are central to the proper functioning of your radios. Many radio users are unaware that their radio batteries are close to expiring or losing power. A lifeless battery can cause many radio failures and warning signs are a first clue to a potential problem (see battery care on the advice page). For many operations radios are used on multiple shifts and are not cared for or inspected on a regular basis. Good quality Motorola radios are meant to last even in the most harsh environments, however, your radio is only as good as the battery inside.
