Battery Chargers

A good marine battery charger restores your batteries on shore power with the right multi-stage profile for their chemistry. This collection includes multi-bank on-board chargers from Victron (Blue Smart, Centaur, Skylla-i), NOCO GENPRO and GENIUS, Xantrex TRUECharge2 and XPLORE, plus DC-DC and battery-to-battery chargers (Victron Orion-Tr and Orion-Tr Smart, Sterling Pro Batt Ultra) for charging a house bank or lithium battery from the alternator, and chargers for ePropulsion, Torqeedo and Dakota Lithium batteries.

How to choose a marine battery charger

• Charge current: roughly 10 to 25 percent of bank capacity in amps for lead-acid; check the lithium maker limits.
• Number of banks: multi-output chargers keep start and house banks separate.
• Chemistry: choose a charger with profiles for AGM, gel, flooded or LiFePO4.
• Environment: waterproof (IP65/IP67) units suit engine rooms and exposed lockers.

What is a DC-DC charger?

It charges one battery from another, usually a house bank from the alternator, with a controlled profile. It protects alternators when charging lithium.

Shore charger or inverter charger?

An inverter charger combines both. See marine inverters and inverter chargers or browse marine batteries.
