 Charger is waterproof, fully automatic and made in the USA. Can charge up to 4 batteries independently.

This is an 8 step, fully automatic 4 bank switch-mode battery charger which automatically determines the condition of your batteries before beginning it’s charge cycle. It will only charge when the batteries need it, and will fully maintain your battery when it is in storage or between uses. Programmed for optimal battery charging and maintenance, with proprietary Rapid Charging Technology(RCT). The smart microprocessor and advanced high frequency design will charge batteries twice as fast as a conventional transformer based marine charger, while always preventing overcharge. This assures you of maximum battery life and less down time. It also utilizes Variable Input Compensation, which means that your charger will work as it should, delivering it’s full, correct voltage and amperage whether or not long extension cords or low AC power are used. Also, with the built in 24 hour mode, this charger will shut off when the charge cycle is completed, but will cycle back on every 24 hours in a “gentle” charge to be sure your batteries are always maintained at peak charge.
