Newmar PT-24-8W Battery Charger

The PT-24-8W Battery Charger offers state-of-the-art smart charging technology tailored for 24-volt marine electrical systems. Perfect for workboats, military and commercial vessels, as well as recreational boats, this charger ensures efficient battery conditioning, maximizing performance and prolonging battery life.

Smart Marine Charging Technology

Specially designed for marine environments, the PT-24-8W interacts intelligently with your boat’s batteries. It delivers an optimized three-stage charging process—bulk, absorption, and float—facilitating rapid recovery and conditioning. This not only enhances battery performance but also extends battery lifespan, making it an essential component for reliable marine electrical systems.

Versatile Battery Compatibility

The charger features a selector switch that adjusts the output voltage to accommodate different battery types, including gel-cell, flooded lead-acid, and AGM batteries. This ensures that each battery type receives the precise charging requirements for optimal performance and longevity.

Temperature Compensation for Optimal Charging

Equipped with an optional temperature compensation sensor, the PT-24-8W automatically adjusts the output voltage based on ambient temperature changes. This feature maintains ideal charging conditions in varying marine climates, protecting your batteries from temperature-related stress and ensuring consistent performance.

Durable Marine-Grade Construction

Built to withstand the harsh conditions of the marine environment, the charger is housed in a rugged stainless steel case with a durable white powder coat finish. The internal circuitry is coated with polyurethane, providing maximum corrosion resistance and ensuring long-term reliability aboard your vessel.
