Newmar PT-80 Battery Charger

Enhance your marine power system with the PT-80 Battery Charger from Newmar’s Phase Three Series. Designed specifically for 12-volt marine applications, this charger delivers intelligent three-stage charging to ensure rapid battery recovery, optimal conditioning, and extended battery lifespan. Whether you’re outfitting a workboat, military vessel, commercial ship, or recreational craft, the PT-80 provides reliable and efficient power management to keep your operations running smoothly.

Advanced Charging Technology

The PT-80 Battery Charger utilizes smart charging technology that interacts seamlessly with your batteries. It employs a three-stage charging process—bulk, absorption, and float—to maximize performance and extend battery life. This intelligent approach ensures your batteries are always maintained at their optimal state, ready to deliver peak performance when you need it most.

Customizable Charging Settings

Adapt the PT-80 to your specific battery type with ease. A convenient selector switch allows you to choose between gel-cell, flooded lead-acid, or AGM battery types, ensuring the charger provides the appropriate voltage for each. Additionally, an optional temperature compensation sensor fine-tunes the output based on ambient temperature changes, maintaining ideal charging conditions regardless of the environment.

Durable Marine-Grade Construction

Built to withstand the harsh marine environment, the PT-80 is housed in a rugged stainless steel case with a durable white powder coat finish. The internal circuitry is polyurethane coated to offer maximum corrosion resistance, ensuring long-term reliability and performance even in the most demanding conditions.
