Mariner prosport battery charger

Had to replace trolling motor batteries in my boat today. I have always used wally world batteries lead acid. As I am getting to old to do this l went with agm Duracell batteries hoping to get a little more life out of fhem. Question I have a pro mariner 3 bank gen 3 battery charger that is a couple years old. I need to switch it from lead acid to agm and I don't have a clue how to do this. Charger is several years old but works good. Can it be switched and what is the process of do I need to buy a new charger. Thanks

It should of came with a plastic type plug you swap out cant
Remember if its on end or side of charger one for Agm cant remembet color and one for lead acid

Contact Pro Mariner if you can’t find your plug in screws to change the settings to AGM. The color for my 20 amp 2 bank charger is blue. This charger on agm settings will also charge Ionic Lithium batterie fully 100% also without a issue. The screw in plug to change is located on the side of the charger. Look for the plastic blue screw in plug.
