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.
Traditional chargers often overcharge or undercharge, shortening battery lifespan. This charger uses a microprocessor-driven three-stage process tailored to your battery type:
Optional equalization for flooded batteries desulfates plates, ensuring longevity. Switch between two- or three-stage modes based on your setup.
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.
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.
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.

Boat owners trust it for reliable starts after stormy nights. RV campers appreciate lithium compatibility for lightweight deep-cycle power. Commercial fleets value global compliance (CE, UL, ABYC) and surge protection. Easy LED display monitors charge status; add a remote for dash mounting.
Yes, it's fully compatible with LiFePO4 lithium-ion batteries, offering dedicated profiles to prevent overcharge and match their voltage needs.
Drip-proof IP32 rating, vibration-resistant build, and multi-position mounting make it ideal for boats, plus ABYC compliance ensures safety standards.
Absolutely—wide 90-265 Vac input handles everything from US 120V to European 230V, even unstable grids abroad.
Xantrex recommends at least 40Ah per bank for efficient charging; smaller banks charge slower but safely.
Yes, parallel stacking up to two units (remote panel needed) doubles output to 40A for larger systems.
Reverse polarity, over-voltage, over-temperature, and circuit breaker safeguards keep your batteries and charger secure.
Quiet mode reduces fan noise significantly, making it suitable for living spaces or overnight use.

TRUECHARGE™3 20A 3 Bank Battery Charger - 12V
TRUEcharge3 battery chargers lead the industry with a small footprint and ultra-compact design. In addition to meeting global safety and regulatory standards, TRUEcharge3 battery chargers feature low electrical interference and efficient power factor-corrected multistage charging. Thanks to their inherent drip-proof design characteristics, the TRUEcharge3 Chargers can be mounted in multiple positions. Unlike its predecessors, TRUEcharge3 is lithium-ion battery compatible.
Designed for recreational and commercial applications worldwide, TRUEcharge3 accepts 90–265 Vac, and 47–63 Hz, which makes traveling abroad and handling poor-quality power a breeze. The easy-to-read display of the TRUEcharge3 12 V models can be enhanced with an optional remote panel. Each model comes with built-in protection against surges and spikes on the AC power line.
Features:
Protection Features:
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:
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.
Electrical Specifications (@ 25 degrees C unless otherwise noted):
