Looking for advice from experienced boaters/fisherman on the best bang for you buck trolling motor batteries. I have a 36 v t motor w/ on a on board Guest charging system. I'm the 2nd owner of boat, purchased 1.5 yrs ago. It had 3 A/C Delco voyager II batteries that the previous owner stated were new. Last month 1 battery keep blowing the fuse. I brought the battery to get tested and it showed that it was reverse polarity. Replaced it. Now another battry is timeing out (14 hr) and not taking charge. I'd like to get advice on whats the average life of trolling motor batteries and what type/manufacture is the best bang for your buck battery for this application. Thanks in advanced and all comments welcomed.
