Attwood Marine & Automotive Battery Charger

The Attwood Marine & Automotive Battery Charger (Model 11901-4) is a compact, dual-voltage charging solution designed for boaters, RV owners, and automotive enthusiasts who need reliable battery maintenance without bench space constraints. This 12V and 6V battery charger combines practical portability with multi-amp versatility, making it suitable for everything from weekend fishing trips to seasonal vehicle storage.

The charger delivers 2-amp and 6-amp charge rates for 12-volt batteries, with a separate 6-amp setting for 6-volt systems—a flexibility that addresses the varying power demands of different marine engines, trolling motors, and auxiliary battery banks. Built-in protections against overcharging, short circuits, and reverse polarity ensure years of trouble-free operation, a critical feature when charging expensive marine batteries in unpredictable environments like boat cabins and engine rooms. The automatic trickle-charge mode prevents battery overcharge damage once a full charge is reached, eliminating the need for constant monitoring during extended dock time or seasonal storage.

This dual-rated charger serves boat owners managing both 12V cranking batteries and 6V deep-cycle systems for trolling motors, as well as automotive and RV applications where mixed battery voltages are common. Its compact footprint (9 x 6 x 9 inches, 6.95 lbs) makes it ideal for galley storage, garage shelves, or workshop benchtops—spaces where larger industrial chargers won't fit. Whether you're prepping for offshore fishing season, maintaining a seasonal ski boat, or keeping backup batteries charged on multiple vehicles, the Attwood Marine & Automotive Battery Charger delivers straightforward, dependable performance in a package that demands minimal deck or storage real estate.
