Customer service was excellent!

I bought this unit in May of 2022. This unit was used to maintain two batteries to a trolling motor and one battery for the boat gas motor. After a year and a half of use, one of the 3 banks stopped maintaining/working. I went on Promariners website and followed directions for a warranty claim. It is
warranted for three years. I forwarded them a copy of my Amazon receipt along with a picture of the serial number. Within about 24 hours they said they were shipping me a new unit. As long as a company stands behind their product when there is a problem, I will stand behind that company and support their product. I did install the new unit this past weekend (3/30/24) and it is working perfectly. I will add that the unit was very easy to install.

These ProSport chargers are the best. This is the third unit I’ve had on as many boats. I maintain three batteries wired for one 12-volt circuit and one 24-volt circuit. Not only are my systems always charged, keeping the batteries fully charged and not allowed to discharge to a critical level has ex
tends their life. Just as important is the customer service. Every time I contacted them, I received a response in 24 hours and had my issue solved in a quick friendly manner. Go for it, you won’t be sorry!

This charger is exactly what I needed to replace its previous model. Although it’s slightly larger than the previous model I managed to get it to fit. The new design features and labels make it easy to figure out what battery is charged and ready to use. Build quality is excellent.

Initial start uu ok. A week or so later (new) batteries were flat. No fault ead on panel. Traced to a loose ground wire on one battery. Seems to me there should have been a panel redout code so indicating (a common problem), would have saved much diagnosis and tracing time!!

My first one died after 5 years but I had to buy another one. I have 3 batteries and run shore power 24/7.

Had the product installed professionally during a full rewire of my boat and a month later all the batteries were dead, we had the battery charger set to flooded lead but a month later when my electrician came back and check he noticed it had switched to AGM and in the process overcharged and Fried $
1000 worth of batteries. We had no idea what caused this so we called pro-mariner support and they said they’ve never heard of this and promised the charger was not at fault and had us set it back to lead acid and install $1000 of new batteries out of my pocket ofcourse and one week later went to use my boat and again all the new batteries were dead, another $1000 loss my electrician came back and saw that the battery charger had switched back to AGM by itself again. We called promariner support again and they rudely refused to help said there charger was not at fault and that to be sure we should bye a new one from them at full price. I’ve used these charges on other boat in years past with no issues but I will never use one again knowing this could happen and the company that makes it doesn’t stand by there products or there customers!
