Xantrex 240AH 12v Lithium Battery

The Xantrex 240AH 12v Lithium Battery is engineered for serious boaters and anglers who demand reliable, long-duration power on the water. Whether you're running electronics, trolling motors, or auxiliary systems during extended trips, this lithium solution replaces traditional lead-acid batteries with modern efficiency and dramatically reduced weight. At 73.9 pounds, it delivers the capacity of much heavier conventional batteries—a critical advantage when managing boat weight, trim, and fuel economy across lakes, coastal waters, and offshore conditions.

Lithium chemistry fundamentally changes how battery power behaves in marine applications. The Xantrex 240AH provides consistent 12-volt output throughout the discharge cycle—unlike lead-acid batteries that sag under load—ensuring stable voltage for GPS chartplotters, fish finders, and autopilot systems. The 240-amp-hour capacity supports extended use without the bulk and weight penalty of lead-acid equivalents, and integrated battery management protects against overcharge, deep discharge, and thermal runaway. This design is purpose-built for marine environments where reliability and fast recharge cycles are non-negotiable.

Experienced boaters upgrading from lead-acid configurations will immediately appreciate the efficiency gain and reduced maintenance burden. The Xantrex 240AH integrates seamlessly into 12-volt marine electrical systems and pairs effectively with onboard chargers and solar charging arrays for renewable power strategy. Installation requires proper marine-grade cabling and a compatible battery management system; consult your vessel's electrical specifications and a marine electrician if needed to ensure safe integration with existing DC loads and charging infrastructure.
