Keep your boat's electrical system running smoothly no matter where the journey takes you with the Newmar PT-24-13W, a powerhouse 24-volt charger designed specifically for demanding marine environments. Whether you're powering navigation gear on a weekend cruiser or supporting critical systems on a commercial workboat, this 3-bank, 13-amp unit delivers reliable charging that adapts to your batteries' needs. Boat owners swear by its ability to revive deep-discharged packs quickly while preventing overcharge damage, ensuring you're always ready for the next voyage.
The heart of the PT-24-13W is its three-stage "smart" technology—bulk, absorption, and float modes—that monitors and adjusts voltage automatically. Start with high-current bulk charging to recover power fast, transition to absorption for full capacity without gassing, and settle into float for maintenance-level trickle without wear. This isn't just charging; it's conditioning your batteries for peak performance and longer life.
Ideal for battery banks from 26 to 130 amp-hours, this charger handles inputs from 90-132VAC or 180-264VAC, drawing just 6.5 amps at 115V full load. Weighing a compact 8.2 lbs (4 kg) in an A-2 sized enclosure (about 12.5" H x 7.7" W x 4.3" D), it fits snugly in tight engine compartments. Operates reliably from -10°C to +60°C, with derating for extreme heat.
Pair it with the optional TCS-12/24 temperature sensor for automatic voltage tweaks based on ambient conditions, or add the RP remote panel for helm control. Equalize mode helps maintain flooded batteries, too.
Picture this: You're anchored offshore after a long day, lights dimming from heavy inverter use. Plug in the PT-24-13W, and it silently restores your 24V system overnight—house bank for appliances, starter for quick starts, bow thruster for maneuvering. Users report 20-30% longer battery life compared to basic chargers, thanks to precise float stages that avoid sulfation.
In commercial setups, its ignition protection (USCG CFR 183.410 compliant) and CE marking mean peace of mind around fuel vapors. No more flat batteries stranding you—current limiting and short-circuit protection keep things safe even under heavy loads.
Mount it vertically in a dry spot, connect AC input via standard plug, and wire the three isolated DC outputs to your banks. Use 10-12 AWG for outputs up to 13A. For best results:
Pro tip: Combine with a battery monitor for full visibility—track charge states remotely via apps for worry-free anchoring.
It works with gel-cell, flooded lead-acid, and AGM batteries via a simple selector switch, delivering tailored charge (up to 28.4V) and float (26.8V for flooded/AGM) voltages.
Three independent isolated banks allow simultaneous charging of separate battery groups, like house, engine, and auxiliary, without interference.
Yes, the stainless steel powder-coated case, marinized internals, and wide temp range (-10°C to +60°C) make it ideal for boats, with corrosion resistance and ignition protection.
Absolutely—operate DC loads directly from AC input without a battery connected, great for bench testing electronics.
Add the TCS-12/24 temp sensor for ambient compensation, RP remote for status at a distance, or enable equalize mode for flooded battery maintenance.
Optimized for 26-130 amp-hour banks at 24V, providing fast recovery without overheating smaller packs or underpowering larger ones.
Current limiting prevents overloads, reverse polarity protection safeguards wiring, and LEDs/alarms signal faults. Compliant with USCG and CE standards.
Invest in the Newmar PT-24-13W for charging that matches the reliability of your vessel. It's not just equipment—it's the difference between getting home under power or calling for a tow. Equip your 24V system today and sail with confidence.
Phase Three "Smart" battery charging technology is now available in a wide range of power levels, allowing you to select the right size, features and flexibility you require for virtually any application from small recreational craft to large live-aboards, workboats and other commercial vessels. These chargers interact with batteries to put them through the optimum three stage charge process which provides for fastest recovery and ideal conditioning, maximizing battery performance and extending battery life.
A selector switch adjusts output voltage to adapt for gel-cell/flooded lead-acid/AGM battery types. An optional temperature compensation sensor also adjusts output for ideal voltage based on changes in the batteries' ambient temperature. All models are housed in a rugged stainless steel case with a durable white powder coat finish, and the internal circuitry is polyurethane coated for maximum corrosion resistance.
