Power Up Your Marine Batteries with Precision

Imagine heading out on the water, only to find your starting battery sluggish or your house bank drained from overnight electronics. That's where the Newmar PT7 steps in as your reliable 12V powerhouse. This compact 7-amp, 2-bank charger delivers smart, three-stage charging tailored for the harsh marine environment, ensuring your batteries recover quickly, perform at their peak, and last seasons longer. Unlike basic chargers that overcharge or underperform, the PT7's intelligent circuitry handles everything from bulk recovery to gentle float maintenance, preventing sulfation and extending life.

Boat owners rave about its simplicity—flip a switch for gel-cell, flooded lead-acid, or AGM batteries, and let it do the work. Whether you're running trolling motors, bilge pumps, or nav systems, this charger keeps you powered without the guesswork.

The Science of Three-Stage Smart Charging

The PT7 employs Phase Three technology: bulk stage floods the battery with maximum current for fast recharge; absorption tops it off at precise voltage to avoid gassing; and float maintains readiness without trickle waste. This process optimizes performance for batteries rated 14-70 amp-hours, perfect for smaller vessels like fishing boats, pontoons, or sailboats.

• Recovers deeply discharged batteries up to 50% faster than single-stage units
• Prevents overcharging that shortens battery lifespan
• Current limiting protects against overloads, even if connected directly to loads

Pro tip: Pair it with your alternator for seamless shore power backup—many users report fewer dead batteries after long idle periods.

Battery Versatility at Your Fingertips

No more fumbling with incompatible chargers. A simple selector switch adjusts output for:

• Gel-cell: 14.0V charge / 13.6V float
• Flooded lead-acid or AGM: 14.2V charge / 13.4V float

Ideal for mixed bank setups common on weekend cruisers. It doubles as a power supply sans battery, keeping DC loads humming during AC outages.

Built to Withstand the Elements

Crafted for saltwater pros, the PT7 features a rugged stainless steel chassis with white powder coat finish and polyurethane-coated internals for ultimate corrosion resistance. At just 3.2 lbs and A-1 case size (10.5" H x 5" W x 2.8" D), it tucks neatly into tight engine compartments.

• Operates from -10°C to +45°C (derate below 0°C)
• Universal AC input: 88-132VAC or 176-264VAC (auto-ranging options)
• LED indicators show charge status; total output ammeter for at-a-glance monitoring
• Meets USCG ignition protection and CE standards for safety

Users in humid tropics or foggy coasts confirm it shrugs off moisture better than plastic competitors.

PT7 Specifications at a Glance

*Dimensions include mounting flanges; full derating details available in technical refs.

Simple Setup for Lasting Results

Installation is straightforward: Connect AC input, wire to your two banks (positive/negative per bank), set battery type, and plug in. Mount vertically or horizontally in a dry, ventilated spot. Monitor via onboard ammeter—no remote needed for this model. For best results, disconnect loads during initial bulk charge and check terminals quarterly for corrosion.

Real-world tweak: Many rig it with an inline fuse for extra protection in rough seas.

Perfect for Your Vessel

From center consoles to cabin cruisers, the PT7 shines where space is premium and reliability is non-negotiable. It's a step up from automotive chargers, with isolated banks preventing cross-charging issues in dual-battery setups.

Why Boaters Trust the Newmar PT7

Beyond specs, it's the peace of mind—two-year warranty, proven in commercial fleets, and designed by power experts who understand boating's demands. Skip the cheap imports that fail mid-trip; invest in gear that starts every time.
