The innovative charging and reconditioning system simplifies and automates battery maintenance. Talk time and life cycle are optimized since manual maintenance programs are not required. Advanced conditioning features allow batteries to be left in the charger for extended periods without causing damage. In addition, the charge of batteries left in the charger is maintained. This ensures that the batteries are always ready when you need them. You can combine all MOTOTRBO IMPRES™ or other radio batteries (except the SL4000 battery) in these chargers.
