Marinco Battery Chargers: Engineered for Life on the Water
Marinco has been a trusted name in marine electrical products since 1972, when founder Bud Toly began building shore power solutions in his Marin County garage. Today, the brand is recognized as a global leader in harsh-environment electrical products — and their battery chargers carry that same uncompromising engineering philosophy on board your boat.
The ChargePro™ Line: Smart, Sealed, and Built for the Sea
Marinco's flagship battery charger offering is the ChargePro™ series, marketed under their Guest brand. The ChargePro™ series features IP68 waterproofing, a non-corroding housing, and a fully sealed, epoxy-filled design — engineered for harsh environments and tested against moisture, salt, shock, and vibration. This isn't just a box with clips — it's a precision instrument built to survive the most punishing conditions afloat.
A microprocessor with Sense-Send™ technology tailors the charge to each battery bank by dividing the available amperage between banks to achieve the most efficient charge possible. Compatible with AGM and flooded deep-cycle batteries, these chargers use a five-stage charging system to quickly restore depleted batteries and maintain them for your next outing.
Versatile Voltage and Multi-Bank Configurations
Guest boat battery chargers from Marinco range from 5A to 40A and are compatible with 12V flooded and AGM lead-acid Group 24–31 batteries. Whether you're running a simple single-battery bass boat or a multi-bank offshore rig, there's a ChargePro configuration to match your system.
- The ChargePro accepts 120V AC or 230V AC input, making it compatible with 12V or 24V single or dual-bank systems.
- Isolated outputs can be put in series or parallel for higher voltage or current flexibility.
- ChargePro chargers meet global industry standards including UL, CE, CSA, ABYC, and California efficiency regulations (CEC).
- A ConnectCharge plug option allows easy assembly to a shore-power inlet with no additional wiring.
The Guest Brand Legacy Within Marinco
Guest by Marinco offers a full line of marine chargers capable of charging all types of lead-acid batteries, including flooded, AGM, and Gel types. The Guest product line has long been a staple for boaters who demand reliability — and the ChargePro series represents the evolution of that trusted lineup, sharing the same housing and mounting dimensions as the traditional Charge Pro Guest chargers while delivering a number of meaningful performance enhancements.
Why Marinco Stands Apart in Battery Charging
Every Marinco product is engineered to withstand corrosion, moisture, and vibration, ensuring safety and durability on board. For boaters, this matters: a failed or compromised battery charger doesn't just leave you stranded — it can create genuine safety hazards in a marine electrical system. From on-board battery chargers to battery maintainers, dynaplates, and switches, Marinco's power conversion and management products are designed to charge, support, and extend the lifespan of rechargeable batteries.
Whether you're a weekend angler who needs reliable cranking power at dawn or a liveaboard boater maintaining a complex multi-bank system, Marinco's ChargePro battery chargers deliver the intelligence, durability, and certifications to keep you confidently powered.
