STERLINGPower ProCharge Ultra On-Board 3-Bank All-Digital Marine Battery Charger - 90-270 Volt AC Input for Worldwide Usage - 4-Stage Charging to Protect Your Boat or RV Battery - 5 Year Warranty

I recently installed this on a boat after an old charger died. It was easy to install and word great. It offers plenty of charging patterns and lights provide useful status updates. A great value compared to other models for marine chargers.

Works perfectly and doesn't overcharge like my Newmar did. With the optional remote provides important information at a glance

I've been using Sterling chargers for about 10 years and have never been disappointed. They are multiple stage units with built in power saving mode to extend the life of your batteries. The 24V 20AMP unit has small screw on terminals and the 24V 30AMP unit has the larger bolt lugs. The unit has multiple preprogrammed charging profiles for different battery types, and one custom charging profile if you want to set up your own bulk, absorption, and float voltages. It can be used as both a charger or a standalone power supply. It is light, quiet, and easy to install. I highly recommend this product.

This is an amazing charger. I’m so glad to have power back on my boat. You need to change it to PS mode instead of DS mode. I could not be happier with this.

Easy install/replacement for my Promatic 30-3 charger. Only issue is that the temperature sensor wite was too short and the company didn’t respond when I inquired about an extension. There are plenty of posts elsewhere on ways to extend them, but I was hoping for something direct/sanctioned by Sterling. I’ll update post if I experience any problems.

I installed this charger on a 31' cruising power boat, with conventional flooded lead/acid batteries, split into two banks: start & house. It works very well, can handle house 12V loads while plugged in and keeping the house bank up. ... Easy to install, seems like a tough unit, the front face has a lot of lights and indicators but is actually pretty simple to read once you study it a little.

Worked great

I like the ability to see how the batteries are charging from the helm without going into the bilge. It was easy to install, although directions would have been nice. Removing the ends to get to the screw holes was interesting. No screws are included for installation.Lastly, it would be nice to view the batteries charge state when you are not connected to shore power. This unit only gives you a read out when connected to shore power. I would have thought it would give you a DC voltage readout when not hooked to the dock.I still give it 4 stars because it does work well, it just needs to have that 1 feature improved for viewing without AC power.
