NewMar PT40U 12V 40 Amp Smart Battery Charger 3-Bank Marine

The NewMar PT40U is a professional-grade 12-volt, 40-amp smart battery charger designed specifically for marine applications including workboats, military vessels, commercial craft, and recreational boats. This intelligent charger delivers a three-stage charging process—bulk, absorption, and float—that ensures fast battery recovery while maximizing performance and extending battery life.

Key Features:

• 40-amp output with three isolated charging banks for independent battery management
• Adjustable battery type selector for gel-cell, flooded lead-acid, or AGM batteries with optimized charge profiles
• Universal input voltage (90-264 VAC, 50-60 Hz) with excellent power factor (.98 @ 115V)
• Rugged stainless steel case with white powder coat finish and polyurethane-coated internal circuitry for maximum corrosion resistance
• Can function as a regulated power supply to run loads directly without battery connection
• Current limiting protection prevents damage from overloading
• Built-in ammeter displays total output current across all banks
• Optional temperature compensation sensor (TCS-12/24) adjusts output voltage based on ambient battery temperature
• USCG ignition protected (CFR 183.410) and ABS-type approved for marine battery charging
