Innovative charging and reconditioning system that streamlines and automates battery maintenance. Talk time and cycle life are optimized as the need for manual maintenance programs is eliminated. Advanced conditioning features allow batteries to be left on the charger for extended periods of time without incurring heat damage. In addition, batteries left in the charger are kept fully charged so they are always ready when you need them. This rapid-rate, tri-chemistry, multi-unit charging system will also charge compatible non-IMPRES batteries. Mix and match any MOTOTRBO IMPRES or non-IMPRES radio battery (except SL 7550 battery) in these chargers.
