ProSportHD12 Onboard Waterproof Smart Marine Battery Charger with Selectable Charging Profiles and Ignition and Reverse Polarity Protection, 12 Amp, 2-Bank

ProSportHD12 Onboard Waterproof Smart Marine Battery Charger with Selectable Charging Profiles and Ignition and Reverse Polarity Protection, 12 Amp, 2-Bank

Keeping your batteries topped off between trips shouldn't mean compromising on charging speed or reliability. The ProMariner ProSportHD 12 Amp 2-Bank Onboard Battery Charger delivers true rated constant current output throughout the entire charge cycle, so you're never left guessing whether your batteries are actually getting a full charge. At the heart of the ProSportHD 12 is a heavy-duty tri-surface extruded heat sink, with upper, lower, and rear-facing surfaces working together for optimal cooling that keeps the charger running at peak efficiency, delivering up to 40% weight savings over traditional epoxy-filled designs. Distributed-On-Demand technology ensures 100% of available amps are always in use, routing power to the bank that needs it most and reducing total charge time without risking overcharging.

Fully automatic 5-stage digital performance charging walks each battery through analysis, bulk charging, conditioning, auto-maintenance, and monthly storage reconditioning, extending battery life while maximizing performance between uses. The auto-maintain energy saver mode monitors batteries during storage and applies power only as needed, keeping AC consumption to a minimum. An expanded LED display with a fuel-gauge-style completion status gauge, a four-color, multi-stage mode LED bar, a System Check OK indicator, and individual Battery Status and Battery Type readouts gives you a clear, real-time dashboard of exactly what's happening across both banks. Compatible with 12V and 24V systems charging two 12V batteries simultaneously, this charger supports Group 24 through Group 31 batteries from 70 to 135 AH per bank across LiFePO4 lithium (see manual or promariner.com/Li for approved batteries), Flooded, AGM, and GEL cell chemistries.

Built for demanding marine environments, the ProSportHD 12 carries an IP67 waterproof rating and features industrial-grade jacketed DC and SJTOW outdoor-rated AC power cables with molded strain reliefs and wire splitters. Pre-wired dual inline waterproof DC fuses and built-in protection against reverse polarity, over-temperature, over-current, over-voltage, and ignition hazards round out the safety package. UL Marine 1236 Listed, CSA C22.2 No. 107.2 Certified, FCC Class B, CEC and DOE Listed, and designed to ABYC A-31 standards. Backed by a 3-year warranty.
