Marinco ChargePro 28210 10-Amp 2-Bank Onboard Marine Battery Charger

The Marinco ChargePro 28210 is a 2-bank onboard battery charger built to keep flooded, AGM, or Gel batteries topped off and ready to go. Rated at 10 amps of charging current, it uses microprocessor control to deliver accurate, battery-safe charging rather than a fixed generic curve. Sense-Send technology reads the actual power needs of each connected battery bank and sends the correct charge profile to that bank, so both banks charge appropriately even if they are at different states of charge. A universal 120/230-volt AC input means the charger can be used with shore power in different regions without a separate converter, which is useful for boats that travel or are stored in different locations. Operation is intuitive, with straightforward controls that do not require reading a manual to get a battery on charge. The charger outputs 12 volts DC and is designed to be permanently or semi-permanently installed onboard, wired to the battery banks it maintains. It is certified to RoHS, UL, CE, CSA, and CEC standards, reflecting testing for electrical safety and construction across multiple regulatory bodies. The Marinco ChargePro 28210 is a direct functional replacement for the Guest 2611A charger, making it a straightforward upgrade path for boat owners replacing an older 2-bank unit.
