NewMar PT2420U 24V 20A Marine Battery Charger 115/230V Input

The NewMar PT2420U is a professional-grade "smart" marine battery charger designed for 24-volt systems aboard workboats, military vessels, commercial vessels, and recreational craft. This intelligent charger delivers optimum three-stage charging (bulk, absorption, float) for fast battery 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, ensuring proper charging for your specific battery configuration. The unit features three isolated output banks with a total maximum output of 20 amps, and an ammeter displays total output current. An optional temperature compensation sensor (TCS-12/24) adjusts output voltage based on battery ambient temperature for ideal charging conditions.
