Newmar PT80 12v 80AMP Charger 115/230V Input Product Description
Keep your boat's batteries in peak condition no matter where your adventures take you. The Newmar PT80 stands out as a powerhouse 12V 80-amp charger designed specifically for demanding marine environments. Whether you're running house loads on a live-aboard yacht, powering navigation systems on a workboat, or maintaining deep-cycle batteries on a recreational cruiser, this charger's intelligent design ensures fast, safe recharges that extend battery life and minimize downtime.
Unlike basic chargers that overcharge or underperform, the PT80 employs advanced Phase Three smart technology. It dynamically shifts through bulk, absorption, and float stages, delivering maximum current early on for quick recovery, then tapers precisely to avoid gassing or sulfation. This isn't just charging—it's conditioning your batteries for reliability when you need it most.
Why Marine Professionals Trust the PT80's Rugged Performance
Built to withstand salt spray, humidity, and vibrations, the PT80 features a corrosion-resistant stainless steel chassis with polyurethane-coated internals. Its universal input handles 90-264V AC from 50-60Hz sources, making it perfect for global cruising or varying shore power. Switch effortlessly between gel-cell, flooded lead-acid, and AGM batteries via a simple selector—no guesswork required.
- High-capacity output: 80 amps total across multiple isolated banks, ideal for battery banks up to 800 amp-hours.
- Overload protection: Current limiting safeguards against spikes, even if loads surge unexpectedly.
- Power supply mode: Run DC loads directly without a battery connected, a game-changer for troubleshooting or emergency power.
- Clear monitoring: Built-in ammeter and LED status lights (or optional remote panel) keep you informed at a glance.
- Temperature smart: Add the optional sensor to automatically adjust voltage for hot engine rooms or cold decks, optimizing every charge.
Compact yet mighty at 14.8 x 9.6 x 5.6 inches and around 15 pounds, it fits tight bilge spaces without sacrificing power. Plus, it meets stringent safety standards for ignition protection and EMC, giving peace of mind in explosive atmospheres.
Mastering the Three-Stage Charge Cycle
Imagine returning from a long day on the water with deeply discharged batteries. The PT80 kicks into bulk mode first, pumping high amps to rapidly replenish capacity—up to 80A without strain. As batteries approach full, it switches to absorption, holding a constant voltage (14.0-14.2V depending on type) to finish filling without excess heat. Finally, float mode maintains trickle current (around 13.4-13.6V) indefinitely, ready for immediate use.
This cycle not only charges faster than single-stage units but prevents common issues like overcharging gel cells or undercharging AGMs. Real-world users report 20-30% longer battery life, translating to fewer replacements and lower costs over seasons.
Perfect Fit for Your Vessel
From sportfishing boats to commercial tugs, the PT80 excels where power demands are high. Pair it with starter and house banks for seamless operation. Its equalize function (on select settings) desulfates flooded batteries periodically, restoring lost capacity. Installation is straightforward: AC input via standard plug, DC outputs to bus bars, and ventilation for cool operation up to 70°C with derating.

Pro Tips for Long-Term Reliability
- Mount vertically in a dry, ventilated area to enhance cooling.
- Use marine-grade wiring (at least 4 AWG for outputs) to handle full amps.
- Pair with a battery monitor for total system oversight.
- Perform equalize monthly on flooded batteries to combat sulfation from infrequent use.
- Clean terminals annually and inspect for corrosion—prevention beats repair.
Owners rave about its quiet operation and efficiency, drawing just 12A at 115V full load. It's not just equipment; it's a reliable partner that keeps you powered through storms or sunny sails alike.
Frequently Asked Questions
What battery types does the Newmar PT80 support?
It works with gel-cell, flooded lead-acid, and AGM batteries. Use the selector switch to match your setup for optimal voltages.
Can the PT80 charge multiple battery banks simultaneously?
Yes, it features multiple isolated output banks (up to 3), allowing independent charging without cross-contamination.
Does it require a temperature sensor for best results?
It's optional but highly recommended for varying climates. The TCS-12/24 sensor adjusts output voltage automatically for safer, more efficient charging.
Is the PT80 suitable as a standalone power supply?
Absolutely. It can power DC loads directly without a battery, making it versatile for testing or backup scenarios.
What makes the three-stage charging better for marine batteries?
Bulk stage recovers capacity fast, absorption completes the charge precisely, and float maintains readiness without overcharging—extending life by preventing damage common in simpler chargers.
How do I install the PT80 on my boat?
Connect AC input to shore power or generator, DC outputs to battery terminals via fuses, and ensure good airflow. Follow marine wiring standards for safety.
What input voltages does it accept?
Universal 90-264V AC input works worldwide, from US 115V to European 230V, with power factor correction for efficiency.
