Newmar Power PT-40U Marine Battery Charger with Smart Three-Stage Technology

PT-40U Battery Charger

Newmars Phase Three Series Battery Chargers employ Smart battery charging technology for 12-volt systems aboard marine applications including workboats, military vessels, commercial vessels, and recreational craft. This charger interacts with batteries, providing the optimum three-stage charge process for fast recovery and conditioning, maximizing performance, and extending battery life.

A selector switch adjusts output voltage to adapt to gel-cell, flooded lead-acid, or AGM battery types. An optional temperature compensation sensor also adjusts output for ideal voltage based on changes in the batteries ambient temperature. This model is housed in a rugged stainless steel case with a durable white powder coat finish, and the internal circuitry is polyurethane coated for maximum corrosion resistance.
