Easy to use, easy to understand

We designed the IC-750 to easily select the right charging mode for your batteries and clearly see the charging status or any errors. Throughout the charging process, the IC-750 keeps you informed at a moment’s glance.

12V Mode

Designed for charging deep-cycle,
12-volt lead-acid batteries.

6V Mode

Designed for charging deep-cycle, 6-volt lead-acid batteries.

Keep Your Batteries Ready.

The IC-750 is a remarkable maintainer for 6V and 12V lead-acid batteries. It automatically determines the maximum capacity of your batteries and constantly monitors charging conditions to ensure that you experience top performance without worrying about constantly checking for charging issues.

Worry-free. Safe to leave connected with zero overcharging.

Most battery chargers continuously trickle charge batteries, making them susceptible to overcharge, which limits battery life. Our intelligent battery maintenance technology monitors battery activity and only begins charging when needed, and allows for continuous operation without user intervention and zero risks of overcharging your battery.

Smart Features to keep you safe. Completely Spark Proof • Fault Protection • Reverse-Polarity Protection


Plus Protection from Short Circuits, Open Circuits, Overheating, Over-Current, and Overcharge


Plug & Play. Battery maintenance made simple.

It’s as simple as connect and forget. No wonder it’s the ultimate in battery maintenance. Quickly connect and disconnect the battery charger whenever you need. It remembers the last mode selected and automatically resumes charging when the power comes back on. The IC-750 keeps any battery fully charged without supervision.


Battery charging with intelligence.

Charging batteries can be frustrating. Often, the charger will not even detect a battery is connected if the charge is too weak or the cells are damaged. Understanding and finding a solution is just as critical. Introducing advanced diagnostics, which analyzes battery feedback and display a particular error pattern if a problem is detected. Each flash pattern tells you what’s wrong, and how to fix it.

Light(s) Condition Cause(s)
Single Flash Battery will not hold a charge and should be checked by a professional.
Double Flash Possible battery short, and should be verified by a professional.
Triple Flash Battery voltage is too high for the selected charge mode. Double check the battery matches the charge mode.
Error LED Solid Red Reverse polarity. Reverse the connections to the battery.
Standby LED Solid Orange Battery voltage is too low for the battery charger to detect the battery.

Battery Charging vs. Battery Maintenance.
Which battery charger is right for you?

Choosing a battery charger depends on your needs. Do you need to recharge a dead battery entirely, or just keep a battery fully charged?
Battery charging means you need to recharge a dead battery fully, whereas battery maintenance requires a mere trickle charge. The IC-750 is designed for charging small vehicle batteries, like those found in motorcycles, ATVs, snowmobiles, or lawn and garden equipment and maintaining batteries in cars, boats, RVs or trucks. The charging time chart not only helps you determine how long it will take to recharge but also its limits between battery charging and battery maintenance.

Efficient design. Compact, yet powerful.

Our combination of electrical engineering and industrial design creates a powerful battery charger with a small form-factor. It uses (HF) high-frequency switch-mode technology to efficiently convert alternating current (AC) to direct current (DC) for battery charging. Its microprocessor adapts to variations in current flow to precisely control the charging to minimize power leaks.

Interchangeable Connectors Included

Mount the included eyelet connectors on your vehicle to make hard-to-access batteries more convenient to charge. Connect directly through the 12V auxiliary from inside a vehicle, or just extend the reach of your 12V portable accessories. Whatever the case may be, our interchangeable battery accessories create a reliable, watertight connection that not only provides maximum current flow, but quick and easy accessory changes.
