Newmar PT-24-20U Battery Charger

The PT-24-20U Battery Charge is a robust and intelligent charging solution designed specifically for 24-volt marine systems. Whether you’re outfitting a workboat, military vessel, commercial ship, or recreational craft, this charger ensures your batteries are optimally charged and maintained, enhancing performance and extending battery life.

Advanced Charging Technology for Marine Applications

Equipped with “smart” marine battery charging technology, the PT-24-20U interacts seamlessly with your batteries to deliver an optimal three-stage charge process: bulk, absorption, and float. This intelligent charging not only ensures fast recovery and conditioning but also maximizes performance and prolongs battery lifespan, making it an essential component for any vessel’s electrical system.

Customizable Charging for Various Battery Types

Adaptability is key in marine environments, and the PT-24-20U excels with its selector switch that adjusts the output voltage to suit gel-cell, flooded lead-acid, or AGM battery types. Additionally, an optional temperature compensation sensor can be integrated to modify the output based on ambient temperature changes, ensuring ideal voltage levels regardless of the operating conditions.

Durable and Corrosion-Resistant Construction

Built to withstand the harsh marine environment, all models of the PT-24-20U are housed in a rugged stainless steel case with a durable white powder coat finish. The internal circuitry is polyurethane-coated, providing maximum corrosion resistance and ensuring long-term reliability even in the most challenging conditions.
