The Pump Plus HO automatic battery charger has a maximum output of 11 amperes. Designed to mount on the vehicle, the automatic battery charger keeps the vehicle's batteries fully charged. 

The battery charger is completely automatic and is for vehicles with dual battery systems. The batteries are automatically charged and maintained fully charged while still being isolated from each other. This new and improved unit contains 2 independent chargers to sense and control the current to the batteries. Thus parasitic loads on one battery have no effect on the other battery. Provision is made also for the connection of remote indicating lights 

A Selector Switch is provided on the charger to operate the Auto Pump 12V either in D.C. mode or in A.C. mode. In either switch position the compressor operates from the vehicle's battery. When "D.C." is selected, the compressor operates whenever the pressure switch senses low system pressure. This is useful when parking the vehicle away from the 110 volt input power. For those operators who wish to limit compressor operation to the times when the shoreline is connected to the vehicle, the Selector Switch should be placed in the "A.C." position. This will operate the compressor when the A.C. power is available, but shuts off the compressor when the shoreline is removed
