Newmar PT-24-13W Battery Charger

Ensure your marine batteries are always in peak condition with the PT-24-13W Battery Charger. Designed specifically for 24-volt systems on workboats, military and commercial vessels, as well as recreational boats, this smart charger delivers reliable performance, extends battery life, and maximizes efficiency through advanced charging technology.

Smart Charging Technology for Optimal Battery Performance

The PT-24-13W Battery Charger employs intelligent three-stage charging—bulk, absorption, and float—to rapidly recover and condition your batteries. This ensures your marine batteries are always ready for the demands of your vessel, providing consistent power and extending battery longevity.

Versatile Battery Compatibility

Adaptable to various battery types, the charger features a selector switch that adjusts the output voltage for gel-cell, flooded lead-acid, or AGM batteries. Additionally, the optional temperature compensation sensor fine-tunes the output based on ambient temperature changes, ensuring optimal charging conditions under all circumstances.
