PT-24-20U Battery Charge

“Smart” marine battery charging technology for 24-volt systems aboard 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. All models are 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.
