Product InformationStore Part Number: GU16153


The Guest model GU16153 is a microprocessor controlled, 3-stage, electronic switching battery charger. Each output produces 12 volts DC at 6 amps per, while maintaining much less AC draw than other comparable chargers. Unlike an old style trickle charger, this unit will not boil off the electrolyte on a properly functioning battery. This unit features a push button interface that allows the user to configure each output to individual battery types. This ensures that each battery gets the individual care that it needs to live a long life.

The 3 color LEDs on the face of the charger will let you know the unit is recharging and maintaining your batteries. This charger is ideal in applications where more than one type of battery is used in a single application, such as a boat, electric vehicle, etc.
