Newmar PT-24-8W 24v Charger 3 Bank 8 Amp

Power Up Your Vessel with Reliable 24V Charging

Keeping batteries charged on a boat isn't just about convenience—it's essential for safety, navigation, and uninterrupted adventures on the water. The PT-24-8W stands out as a compact powerhouse designed for 24-volt systems, delivering steady 8-amp output across three independent banks. Whether you're running house loads on a sailboat, powering electronics on a fishing vessel, or maintaining starter batteries on a cruiser, this charger ensures quick recovery from deep discharges while protecting against overcharging.

Boat owners often face humid, salty environments that chew through lesser chargers. Built tough with a stainless steel enclosure and powder-coated finish, plus polyurethane-coated internals, it laughs off corrosion and stands ready for years of service in engine rooms or battery compartments.

Master the Three-Stage "Smart" Charging Process

Unlike basic chargers that dump power indiscriminately, this unit employs intelligent circuitry for a precise three-phase cycle: bulk for rapid replenishment, absorption to fully saturate cells without gassing, and float to maintain peak readiness. This method combats sulfation—a common battery killer—and can double lifespan compared to constant-voltage setups.

Picture returning from a long offshore trip with depleted banks. The charger senses the state, ramps up current safely (with built-in limiting), then tapers off seamlessly. LED indicators and optional remote panels keep you informed at a glance, even from the helm.

Technical Edge for Marine Demands

Handles input from 85-264 VAC (universal worldwide compatibility), drawing just 2.8A at 115V or 1.4A at 230V full load. Power factor exceeds 0.93, minimizing draw from generators or shore power. Three isolated banks prevent cross-charging, ideal for separating thruster, engine start, and house batteries.

Operate as a standalone power supply too—no battery needed for light DC loads. Equalize mode (on select settings) equalizes flooded batteries for balanced performance.

Built for the Harsh Marine World

• Corrosion-Proof Design: Marinized components shrug off spray, humidity, and vibration.
• Safety First: Ignition-protected (USCG compliant), EMC certified, with clear status LEDs/audible alarms.
• Flexible Install: Compact A-2 footprint fits tight spaces; optional drip shield for overhead mounting.
• Proven Reliability: Two-year warranty backs construction that thrives where others fail.

Perfect Fit for Your Boating Needs

Scale up from smaller 12V setups or complement larger siblings in the PT series for bigger banks. Sailors love it for windlass and autopilot banks; powerboaters for twin engines and generators. In commercial ops, it keeps workboats running without downtime.

Real-world tip: Position near batteries to cut voltage drop—wires sized to 8A keep efficiency high. Monitor via ammeter for total output, spotting issues early.

Extend Battery Life and Cut Costs

Smart charging avoids the pitfalls of under- or over-charging: no dry-outs, no stratification. Users report 20-30% longer battery life, translating to fewer replacements and more time on the water. Pair with quality deep-cycle batteries for a system that punches above its weight.
