Precision Chargers On-Board Marine Battery Chargers It's simple - you can buy new batteries, or start taking care of the ones you already own. Precision Chargers protect your batteries every time you plug them in, so they'll last almost as long as the Minn Kota they're powering Low-Line Voltage Compensation Outlets are supposed to put out 120 volts. But overloading outlets or using long extension cords can lower that output, and make charge times go up. That's why our Precision Chargers compensate for low-voltage outlets to deliver a fast, consistent charge, every time. Automatic Temperature Compensation Charging your batteries at higher or lower temperatures can damage your battery. But chargers equipped with Automatic Temperature Compensation fight back. They sense outside temperature fluctuations and adjust accordingly - providing a fast, accurate charge. Comprehensive LED Display From the LED display on our Precision Chargers, you can select your battery type by bank, so your battery gets the exact charge it needs. You can also monitor each bank's connection status, power status, state of charge and selected battery type. Battery Equalization Precision Chargers equalize your battery with every charge - cleaning sulfate off the plates to prevent the battery from wearing down. And at the push of a button, you can activate a full, thorough equalization. Note: only Flooded Lead-Acid batteries should be equalized. True-Rated Output Precision Chargers supply your battery with a more consistent 15-amp output - ensuring the fastest possible charge, and getting you back out on the water sooner. Durable Precision Charger Design With rugged, marine-grade aluminum housing and fully corrosion-resistant design, our Precision Chargers are built with the durability you'd expect from a Minn Kota. They're also half the weight and more compact than traditional chargers. Digital Control A microprocessor-based design enables our chargers to continually monitor the temperature and state of charge of your battery. It means a faster, more regulated, precise charge for your battery - and a longer day of worry-free fishing for you. Multi-Stage Charging By controlling the voltage and current your battery gets throughout the charging cycle, our on-board chargers ensure a fast, safe and precise charge. AC Plug Holder Included with all of our on-board chargers, this convenient holder keeps the charger plug dry, safe and easily accessible.
