We’re happy with the ACTivator. We’ve tried a bunch of different chargers, and this is the first thing that works. It keeps batteries alive. We’ve tried everything, even the Motorola conditioner/ charger, and it didn’t do anything for our batteries. We tested the ACTivator, and it absolutely amazed at how quickly it brought life back to batteries. A battery will actually last an entire shift. Even after we got the Motorola charger, we though we were just out of luck with batteries. Batteries had been a very sore subject around here for a long time.
