Xantrex TRUECHARGE™3 20A 3 Bank Battery Charger - 12V Product Description
Why Choose the Xantrex TRUECHARGE™3 20A 3-Bank Charger for Your Power Needs
Imagine powering your adventures without worrying about dead batteries or unreliable charging. The Xantrex TRUECHARGE™3 20A 3-bank 12V charger steps in as a reliable workhorse, blending compact design with smart technology. Perfect for marine enthusiasts, RV owners, and commercial operators, this charger handles everything from flooded lead-acid to modern lithium-ion setups. Its global voltage acceptance means no adapters needed on international trips, and the drip-proof build lets you mount it almost anywhere—inside engine compartments or exposed cabins.
What sets it apart? Beyond basic charging, it employs intelligent algorithms that extend battery life while delivering peak performance. Users rave about its ability to revive deeply discharged batteries, a game-changer for those long off-grid days.
Smart Multistage Charging: Bulk, Absorption, and Float Explained
Traditional chargers often overcharge or undercharge, shortening battery lifespan. This charger uses a microprocessor-driven three-stage process tailored to your battery type:
- Bulk Stage: Rapidly restores 70-80% capacity with maximum current, getting you back online fast.
- Absorption Stage: Gently tops off the remaining charge, avoiding heat buildup and gassing.
- Float Stage: Maintains full charge indefinitely without trickle risks, ideal for storage.
Optional equalization for flooded batteries desulfates plates, ensuring longevity. Switch between two- or three-stage modes based on your setup.
Power Factor Correction: Maximize Shore Power Efficiency
In tight marina slips or RV parks with shared power, efficiency matters. Power factor corrected (PFC) design draws less current from your AC source, over 80% efficient. Run chargers alongside microwaves or air conditioners without tripping breakers—freeing up power for what you love most.
Battery Versatility and Bank Independence
Three isolated banks charge independently, perfect for house, engine start, and thruster batteries. Supports gel, flooded, AGM, and LiFePO4 chemistries with customizable voltage settings (14.2-15.5V charge, 13.4-13.8V float). Minimum 40Ah bank recommended per output for optimal results. Parallel stack two units (with remote) for 40A power.
Rugged Protection and Mount Anywhere Design
Built for real-world abuse: reverse polarity won't fry connections, over-temp shuts down safely, DC over-voltage guards electronics, and circuit breakers reset effortlessly. IP32 drip-proof rating and multi-position mounting (0°-60°C operation) suit wet, dusty environments. Quiet mode minimizes fan noise for stealthy overnight charging.

Frequently Asked Questions
Can this charger handle lithium-ion batteries?
Yes, it's fully compatible with LiFePO4 lithium-ion batteries, offering dedicated profiles to prevent overcharge and match their voltage needs.
What makes it suitable for marine use?
Drip-proof IP32 rating, vibration-resistant build, and multi-position mounting make it ideal for boats, plus ABYC compliance ensures safety standards.
Does it work with worldwide power sources?
Absolutely—wide 90-265 Vac input handles everything from US 120V to European 230V, even unstable grids abroad.
How do I know if my battery bank is large enough?
Xantrex recommends at least 40Ah per bank for efficient charging; smaller banks charge slower but safely.
Can I connect multiple chargers together?
Yes, parallel stacking up to two units (remote panel needed) doubles output to 40A for larger systems.
What protections does it include?
Reverse polarity, over-voltage, over-temperature, and circuit breaker safeguards keep your batteries and charger secure.
Is it quiet during operation?
Quiet mode reduces fan noise significantly, making it suitable for living spaces or overnight use.

Three-Stage Charging
Multistage charging ensures batteries receive optimum charging, but with minimal wear and tear, regulating the voltage and current delivered to the batteries in three automatic stages:
- Bulk: Replaces 70–80% of the battery’s state-of-charge at the fastest possible rate
- Absorption: Replenishes the remaining 20–30% of charge, bringing the battery to a full charge at a slow, safe rate
- Float: Voltage is reduced and held constant to prevent damage and maintain batteries at a full charge for the remaining 20–30% of charge, bringing the battery to a full charge at a slow, safe rate
Power Factor Corrected (PFC) Charging
Less shore power is required for charging batteries, freeing up more usable AC power for running electrical devices and appliances and reducing the likelihood of tripping shore power breakers.
