Xantrex TRUECHARGE™3 40A 3 Bank Battery Charger - 12V Product Description
Imagine powering your boat, RV, or off-grid setup without worrying about dead batteries or unreliable charging. The Xantrex TRUECHARGE 3 40A 3-bank model steps in as a compact powerhouse, delivering smart, multistage charging that keeps your batteries in peak condition. Its sleek design fits snugly into tight spaces, while handling everything from flooded lead-acid to modern lithium-ion packs with ease.
What sets this charger apart? It thrives in real-world chaos—fluctuating shore power, bumpy marine environments, or dusty RV storage. With universal AC input, it adapts to whatever voltage you throw at it, from sketchy international outlets to stable 120V docks. No more guessing games; microprocessor smarts optimize every charge cycle for longevity and performance.
Why Boat Owners and RV Enthusiasts Rely on This Charger
In the demanding world of recreational boating or commercial fleets, downtime from battery issues isn't an option. This unit shines by independently charging three battery banks simultaneously, perfect for house banks, starters, or thruster batteries. Its drip-proof build (IP32 rated) laughs off splashes and humidity, and multi-position mounting means it slots into engine compartments or under benches without fuss.
- Versatile Battery Support: Dial in settings for gel, AGM, flooded, or LiFePO4—switch effortlessly between chemistries without extra gear.
- Quiet Operation: A dedicated mode keeps fans hushed during those peaceful anchorages or overnight camps.
- Stackable Power: Link up to two units in parallel for double the amps when your setup demands more (remote panel unlocks this).
- Revive the Drained: Pulls batteries back from the brink, even at ultra-low voltages that would stump lesser chargers.
- Power-Smart Design: Power factor correction squeezes more efficiency from your shore connection, leaving amps free for lights, fridges, or inverters.
Mastering Battery Health with Three-Stage Charging
Batteries aren't one-and-done; they need nurturing. This charger's automatic three-stage process mimics nature's balance—fast refill, gentle top-off, and safe maintenance—cutting wear and maximizing cycles.
- Bulk Stage: High-current surge restores most capacity quickly, like gulping water after a long hike.
- Absorption Stage: Slows to a trickle, fully saturating cells without gassing or overheating.
- Float Stage: Holds at a trickle voltage, ready for instant use while preventing overcharge sulfation.
Bonus: Built-in equalization nudges flooded batteries to shed imbalances, extending life in high-demand setups like trolling motors or solar arrays.
Built Tough: Layers of Protection for Peace of Mind
Harsh elements and power glitches? Covered. Reverse polarity won't fry connections, over-temp sensors throttle output before damage, and circuit breakers reset after surges. DC over-voltage guards your electronics, ensuring your investment stays safe from the inside out.
Perfect Fit for Marine, RV, and Beyond
Boaters love it for maintaining multiple banks during long cruises—charge your engine start, house, and bow thruster independently. RV folks pair it with generators for off-grid boondocking, reviving deep-cycle banks after days of AC loads. Commercial ops? Its global compliance and ruggedness handle fleet maintenance without breaking a sweat. Pair with solar controllers for hybrid systems, and you've got reliable power wherever adventure calls.
Installation is straightforward: Three positive leads to your banks, one shared negative, AC cord to shore. The LED display shows charge status at a glance; add a remote for helm monitoring. Temps from freezing decks to hot engine bays? It operates 0-60°C, storing even colder.

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.
