Auto Charge 20

Product Code: 091-10-12


  • 20A amp for charging 3 battery banks.
  • Automatically charges three battery banks utilizing independent sense circuits that control voltage and current to each battery, thus parasitic loads on one battery have no effect on the others
  • Full amperage output is available to any battery if the adjacent banks do not require charging, optimizing use of available power in charging banks with differing parasitic load rates
  • Designed for rigors of emergency vehicle use; heavy-duty aluminum case with protective front panel plate and wire strain relief
  • 3 year warranty

The Auto Charge 20 is a fully automatic battery charger for vehicles with three independent batteries which must be charged. The charger contains 3 separate and independent circuits, 1 for each battery. Each battery is independently sensed and charged as required. Even though the total for all three outputs is limited to 20 amperes any one of the batteries may receive up to 20 amperes if the other batteries do not require a charge. Rugged construction permits vehicle mounting or the charger may be wall mounted. Optional indicators are available to remotely display when the batteries are charged.
