Battery Chargers

Simply put, Smart Technology incorporated today in the manufacturing of Onboard Battery Chargers, by companies such as Dual Pro, Guest, Minn Kota, Newmar, ProMariner, & Xantrex, has made every Mariner’s life a little easier. The technology built into most of these charging units today can accommodate & provide the appropriate charge to each individual battery in your bank, whether you have Deep – Cycle Flooded, AGM, or GEL batteries installed on your boat.

When your boat is tied up in the slip & plugged into shore power these charging units will perform flawlessly and deliver the correct amount of current & amperage to maintain your batteries at optimum performance. Once you leave the slip & are underway, for a day or a lengthy cruise, we recommend a voltage regulator with smart technology & a high – output alternator available from Balmar. These two electrical components will maximize the efficiency of your charging system.

Captain’s Marine Supply has an extensive line of top – quality onboard battery chargers with a wide selection of amperage output’s & battery bank requirements to choose from. So, cruise on by & shop all of our quality onboard charging systems today!
