Keep your boat's batteries primed and ready for the next adventure with the Newmar PT14W, a powerhouse 14-amp, three-bank charger designed for the demanding world of marine and RV life. Imagine pulling into your slip after a long day on the water, only to find your house, engine start, and thruster batteries drained. This smart charger steps in with precision three-stage charging to restore them efficiently, preventing overcharge while maximizing capacity and lifespan. Built tough for salty air and rough conditions, it's the reliable choice for boaters who can't afford downtime.
In harsh marine environments, ordinary chargers falter—corroding internals, inconsistent output, or failure under load. The PT14W stands apart with its stainless steel chassis finished in durable white powder coat and polyurethane-coated circuitry that shrugs off moisture and salt. It's fully universal, accepting 115-230V AC input without fuss, whether you're docked stateside or cruising abroad. Users rave about its quiet operation and consistent performance, even in engine rooms where heat and vibration are constant.
Unlike basic trickle chargers that can boil batteries dry, this unit employs intelligent circuitry:
A simple selector switch adapts to gel-cell, flooded lead-acid, or AGM types, ensuring peak performance. Pair it with the optional temperature sensor for automatic adjustments based on ambient conditions—crucial in engine bays that swing from freezing winters to scorching summers.
The PT14W isn't just a charger; it's a complete power management solution:
Boat owners use it for house banks powering fridges and electronics, start batteries for reliable cranking, and bow thrusters. RV enthusiasts appreciate its ability to handle deep-cycle setups during off-grid camping. In commercial vessels or workboats, it supports 28-140 amp-hour batteries per bank, scaling effortlessly. Ignition-protected and compliant with key safety standards, it meets rigorous demands without compromise.
Mount it vertically in a dry, ventilated spot away from batteries to minimize fumes. Use marine-grade wire (10-12 AWG recommended) for outputs, fused at 20 amps. Connect AC input via a GFCI-protected shore power circuit. Test banks individually post-install to verify isolation—no cross-charging here. Pro tip: Position near your panel for short runs, and add the temp sensor if batteries see wide temp swings for 10-20% longer life.
It handles gel-cell, flooded lead-acid, and AGM batteries via a built-in selector switch for customized charging profiles.
Yes, it functions as a stable DC power supply for loads up to 14 amps, ideal for testing or direct powering.
An optional TCS-12/24 sensor automatically adjusts output voltage for optimal charging across -10°C to +60°C ranges.
Three isolated banks allow simultaneous charging of separate battery groups, like start, house, and accessory banks.
Absolutely—its corrosion-resistant build, ignition protection, and compliance with USCG standards make it a top pick for boats.
The three-stage process starts with high-current bulk charging to recover them quickly and safely, preventing damage.
An ammeter shows total output, while LEDs indicate bulk, absorption, float, or faults. Optional remote panel available.
14 Amp Phase Three Series Battery ChargerThe "Smart" Charger for Almost Any ApplicationPhase Three "Smart" battery charging technology allows 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 choice of a natural or durable white powder coated finish, and the internal circuitry is polyurethane coated for maximum corrosion resistance.
