Xantrex TRUECHARGE™2 10Amp Battery Charger - Dual Bank 12V

Why Choose the Xantrex TRUECHARGE™2 10A Dual Bank Charger for Your Marine Setup?

Marine enthusiasts and commercial operators know the frustration of unreliable power sources on the water. Whether you're running trolling motors, electronics, or backup systems on your boat, a dependable battery charger is essential. The Xantrex TRUECHARGE™2 10A dual bank model stands out with its compact design that fits into tight engine compartments or cabins, delivering reliable 12V charging to two separate banks simultaneously. Its microprocessor-driven intelligence adapts to various battery types—AGM, flooded, gel, or calcium lead-acid—ensuring optimal performance without overcharging or underperformance.

What sets this charger apart is its global compatibility. With an auto-ranging input from 90-265V AC, it handles everything from shore power to generators in remote marinas worldwide, even with inconsistent voltage. Power factor correction maximizes efficiency, drawing less AC power so you can run other onboard gear without overloads.

Key Performance Advantages for Everyday Reliability

Built for the demands of saltwater environments, this charger features a drip-proof IP32 rating, allowing versatile mounting—even in engine rooms with ignition protection certification. Its three-stage charging process (bulk, absorption, float) revives deeply discharged batteries, extending their lifespan and reducing replacement costs.

• Temperature Compensation: Built-in sensor adjusts charge rates based on ambient conditions, preventing damage in hot bilges or cold decks.
• Multi-Bank Independence: Each 12V bank gets dedicated 10A output, perfect for house and starting batteries on mid-size vessels.
• Compact Footprint: At just 8.8 x 5.4 x 2.7 inches and lightweight, it installs horizontally, vertically, or upside down with easy-access wiring compartments.
• Robust Protections: Safeguards against reverse polarity, over/under temperature, DC surges, and battery overcharge keep your system safe.

Users report fewer battery failures after switching to this charger, thanks to its ability to maintain float voltages precisely (13.4-13.8V) while supporting banks as small as 20Ah.

Practical Installation and Maintenance Tips

Setting up is straightforward for DIY boaters or pros. Connect the shared negative terminal and individual positives to each bank using marine-grade wire. Mount it away from direct water spray but where ventilation is good—its over-temperature protection handles the rest. Pair it with an optional remote battery temperature sensor for even smarter charging in varying climates.

For maintenance, a simple LED indicator shows charge status—no complex diagnostics needed. Regularly inspect connections for corrosion, common in marine settings, and let the charger's algorithms handle the rest. This charger excels in prolonging battery health, often adding seasons of service to your deep-cycle banks.

How It Outperforms Standard Chargers in Real-World Scenarios

Unlike basic plug-and-play chargers that cook batteries with constant high amps, this model's multistage intelligence mimics a smart maintainer. It powers through bulk charging for quick recovery, then tapers to safe float modes. Efficiency over 80% means less heat buildup and energy waste, ideal for solar-hybrid setups or limited generator runtime.

In commercial fishing or charter boats, dual-bank capability means never swapping batteries—charge both engine start and electronics banks at once. Its universal input shrugs off voltage dips from aging generators, a common pain point in off-grid ops.
