Marinco ChargePro 6-Amp 1-Bank Waterproof On-Board Battery Charger, 12 Volt, Replaces Guest 2608A

The Marinco ChargePro 28106 is a 1-bank, 6-amp onboard battery charger built to keep a single 12-volt battery bank topped off and ready, whether the boat sits at the dock or in storage. It uses microprocessor control paired with Marinco's Sense-Send technology, which reads the condition of the connected battery and sends only the charge current that battery actually needs, helping prevent overcharging while still delivering a full, accurate charge.

The charger is compatible with flooded, AGM, or gel lead-acid batteries, so the same unit can be used across different battery chemistries without separate settings. It accepts a universal 120/230-volt AC input, making it usable in a range of shore power setups, and outputs 6 amps at 12 volts DC to a single battery bank. Operation is intuitive, with the unit designed for straightforward set-and-forget charging rather than manual mode switching. The housing is waterproof, suiting it to the onboard marine environment where charging equipment is exposed to moisture. The Marinco ChargePro 28106 is a direct replacement for the Guest 2608A charger, backed by a 1-year limited warranty.
