The Kussmaul Auto Charge 20 is a fully automatic, triple-output battery charger designed to independently charge and maintain three separate 12-volt battery banks. Engineered for fire apparatus, rescue vehicles, ambulances, and other emergency or specialty vehicles, the Auto Charge 20 uses three independent sensing and charging circuits to provide each battery bank with charging current based on its individual condition and electrical demands.

Each battery is independently monitored and charged, preventing parasitic loads connected to one battery bank from affecting the charging performance of the other batteries. Although the charger provides a maximum total output of 20 amps, any individual battery bank can receive up to the full 20-amp output when the other batteries do not require charging. This intelligent distribution of available charging power helps optimize battery recovery in vehicles with different electrical loads across multiple battery banks.

The Auto Charge 20 features a heavy-duty aluminum enclosure with a protective front panel plate and wire strain relief for demanding vehicle installations. The charger can be mounted directly on the vehicle or installed on a wall, while optional remote indicators provide convenient monitoring of battery charging status.
