Product Description

Up to 40% lighter than the previous Generation 2 Series of ProSport chargers that were epoxy filled, these latest models now feature an expanded LED display that includes a system check OK function and a battery bank trouble status alert for simplified detection of wiring problems or failing batteries.

Unlike conventional chargers that typically impose an amperage limitation per bank, the ProSport’s Distributed-On-Demand Charging Technology ensures that 100% of the available charging amperage is fully utilized to meet the unique demands of each onboard battery.

ProSport’s exclusive Sequential Multi-Stage Charging process delivers three sequenced modes of operation: Charging, Conditioning and Maintenance that fully charges your batteries while maximizing their service life. Two user-selectable performance charge profiles can be digitally selected for flooded, standard or AGM-type batteries with a third High Performance AGM profile on 20A dual bank models and color-coded programming caps, allowing the ProSport to be simply reprogrammed in the event batteries on board are changed to a different type.

Even when your boat is in storage the ProSport protects your batteries with an additional Recondition Mode that will automatically recondition all batteries for up to three hours a month, further extending battery life.

      Comments about ProSport 20 Heavy Duty Marine Battery Charger, 20A, 12/24V, 2 Bank Charger:

      Replaced my Charles 15amp 3 bank charger that had burned up. Only needed 2 banks and the price was right. Thought it could be hard wired but was surprised to find it had a cord. No problem installed an outdoor weather proof receptacle in the engine compartment and plugged in! Installed 6 months ago and has worked great with the 600 CCA Starting Battery and Deep Cycle Battery. Leave it plugged in 24/7 in my back yard and it goes through its cycles, great charger.

          I replaced a Guest charger with this on my '05 Grady Marlin. The Guest, which is supposed to be a piece of junk, lasted 8 years. This one gave out in less than 5 months. The AC input light won't come on and I have 119 volts going to it. Before it died, it worked fine but come on...5 months?

            Comments about ProSport 20 Heavy Duty Marine Battery Charger, 20A, 12/24V, 2 Bank Charger:

            Have this hooked to a 220ah battery and a small 60AH battery. 20A is about C/10 for the 220ah battery, so this should be fine.

            Never goes into maintain - always putting 14.7v on the batteries, causing battery degradation.

            Call up the manufacturer, and they say that the 220ah battery is "too big" and that's the problem. Huh? You can charge it with a tiny charger, just takes longer. They also admitted that the charger uses voltage (not current) to determine when to go into float. I don't see size limitations on any of the decriptions I find online.

            I just can't understand how bad chargers exist - 3 stage LA charging is not rocket science.
