Newmar PT80 12v 80AMP Charger 115/230V Input

The Newmar PT80 12v 80AMP Charger 115/230V Input is a marine-grade three-stage smart battery charging system engineered for serious boaters and vessel operators who demand reliable power management on the water. Whether you're running a recreational center console, cruiser, or larger commercial vessel, this intelligent charger automatically adapts to your 12-volt battery bank's needs, eliminating guesswork and protecting expensive marine batteries from overcharge, undercharge, and sulfation damage. The dual input voltage capability (115V and 230V) means seamless transition between shore power at your home dock and international marina facilities.

This charger's three-stage smart technology automatically cycles through bulk charging, absorption, and float modes—continuously monitoring voltage and amperage to deliver the precise charge your battery requires at each stage. The 80-amp output provides rapid recharge cycles after engine-off loads have drained your house bank, getting you back on the water faster while minimizing heat generation and battery stress. At 19 pounds, it's compact enough for tight engine room installations yet robust enough to handle the demanding electrical environment of saltwater and freshwater vessels, with protection against voltage spikes and shore-power fluctuations.

Cruisers, trawlers, and liveaboard operators benefit most from this charger's reliability and automation—especially those making extended trips or maintaining multiple battery banks for propulsion, house loads, and auxiliary systems. Installation requires connection to your 12-volt house bank and available shore power (either 115V or 230V), making it ideal for vessels already equipped with proper electrical infrastructure. The PT80 pairs seamlessly with lead-acid and lithium battery systems, delivering the controlled charging profile each chemistry demands without manual adjustment or constant monitoring.
