Dual Pro Battery Chargers by PRO Charging Systems

The Dual Pro Lineup at Battery Mart

Dual Pro offers several distinct product lines, each built for a specific type of user and application. Here's a look at what you'll find in our catalog.

RealPRO Series — Waterproof Marine Chargers

The RealPRO Series is built for boaters who need a truly waterproof onboard charger. Available in 1-, 2-, 3-, and 4-bank configurations, these chargers are designed to handle the punishment of a marine environment while keeping your trolling motor and starting batteries topped off and ready. Compact and fully automatic, RealPRO chargers are a favorite for anglers and recreational boaters alike.

Professional Series — High-Output Multi-Bank Charging

The Professional Series is Dual Pro's flagship line for serious applications. Available in 1- to 4-bank configurations with output up to 60 amps, these chargers come in versions compatible with AGM and Wet Cell batteries, as well as versions with auto-detect for Lithium batteries. If you're running a multi-battery boat, RV, or work vehicle and need reliable, fast charging, the Professional Series delivers.

Sportsman Series — Multi-Bank Charging for Active Users

The Sportsman Series bridges the gap between the waterproof RealPRO and the high-output Professional Series. Available in 2-, 3-, and 4-bank options, Sportsman chargers are well-suited for bass boats, kayak fishing setups with multiple batteries, and other recreational applications. Like the Professional Series, Sportsman chargers are available in both standard AGM/Wet Cell and Lithium-compatible configurations.

Eagle Performance Series — Golf Cart & Industrial Charging

The Eagle Performance Series is Dual Pro's answer for golf cart, low-speed vehicle, scissor lift, and aerial lift charging. Covering 24V, 36V, 48V, 60V, and 72V systems, Eagle chargers are available as portable units and onboard chargers, with a wide variety of connector configurations to match Club Car, Yamaha, EzGo, JLG, Genie, BilJax, and other popular equipment brands. Scissor lift-specific models are also available for a number of OEM applications.

Industrial Series — Dependable Workhorse Chargers

For floor scrubbers, pallet jacks, forklifts, and other industrial equipment running on 24V or 48V battery systems, the Dual Pro Industrial Series provides efficient, reliable charging day after day. These chargers are built to handle the demands of commercial environments and shift-based operation.

Sentinel 10 — Fleet Maintenance & Multi-Battery Charging

The Sentinel 10 is a 10-bank professional charger and maintainer designed for dealers, service shops, and fleet operators who need to charge and maintain multiple batteries simultaneously. It's an efficient tool for keeping inventory batteries healthy and ready to go.

ZOMBIE Battery Reviver

The ZOMBIE is a 12V, 4-bank charger designed to revive deeply discharged batteries that a standard charger might reject. If you have batteries that have sat too long or been over-discharged, the ZOMBIE is worth trying before writing them off.

Battery Fuel Gauges & Accessories

Beyond chargers, Battery Mart also carries Dual Pro's battery fuel gauges in round, horizontal, and vertical panel-mount styles for 12V through 72V systems — including a dedicated marine gauge for trolling and cranking batteries. We also stock cable extensions, alligator clip kits, and the Eagle Performance Series Remote Display Indicator for installations where you want status visibility away from the charger itself.

Frequently Asked Questions About Dual Pro Battery Chargers

What types of batteries are compatible with Dual Pro chargers?

Most Dual Pro chargers are designed for flooded lead-acid (wet cell) and AGM batteries. Many newer models — particularly in the Professional and Sportsman Series — are also available in Lithium-compatible versions that can auto-detect battery chemistry. Gel battery configurations are available through the manufacturer directly. Check individual product listings for compatibility details.

Are Dual Pro chargers safe to leave connected long-term?

Yes. Dual Pro chargers use multi-stage charging that transitions to a maintenance/float mode once the battery is fully charged, making them safe for long-term connection. This is especially useful for seasonal equipment like boats and golf carts that sit unused for extended periods.

What do the LED fault codes on Dual Pro chargers mean?

Since 2007, Dual Pro chargers have been equipped with LED fault indicators. If you see blinking LEDs, here's what each pattern indicates:

• 1 Red Blinking LED — No Battery Detected: The charger cannot detect a battery and will not allow current to flow. Unplug the AC power, then check your battery connections for proper polarity and look for corrosion or loose terminals.
• 2 Red Blinking LEDs — Forming State Timeout: The battery voltage hasn't risen above 1.75 volts per cell within the first three hours of charging. This usually indicates a battery issue. Reset by unplugging and reconnecting the AC power.
• 3 Blinking LEDs — Overall Timer Shutdown: The charger hasn't completed its charge cycle within the factory-set time limit, which may indicate a battery problem. Reset by disconnecting and reconnecting AC power.
• 4 Blinking LEDs — Internal Overtemp Shutdown: The charger has detected excessive internal heat and stopped charging to protect itself. Unplug AC power to reset and ensure the charger has adequate ventilation.
• 5 Blinking LEDs — Over-Voltage Protection: The charger has detected a possible defect in its output circuitry. Stop using the charger immediately and contact us or Dual Pro directly for service.

Can I use a Dual Pro multi-bank charger on batteries of different sizes?

Yes, each bank on a Dual Pro multi-bank charger operates independently. You can charge batteries of different sizes simultaneously, and each bank will complete its charge cycle based on the individual battery's needs.

How do I know which Eagle Performance Series charger is right for my golf cart or scissor lift?

The key factors are your system voltage (24V, 36V, 48V, 60V, or 72V), your required amperage, and your connector type. Many OEM-specific models are available for Club Car, Yamaha, EzGo, JLG, Genie, and others. If you're unsure, feel free to contact us and we'll help you find the right match.

What is Dual Pro's warranty policy?

Warranty terms vary by product series. Please refer to the individual product listing or the documentation included with your charger for warranty details. For questions about returns or exchanges, see our returns policy.
