Hey everyone, hope your summer is going well!! I had the above battery (maintainance free) for 2 years and used it with my trolling motor. In June it did not hold the charge as long 2 hours vs. 5 -6 hours, so I returned it for the same battery. Now they have the kind that you add water to. Anyway, I found that after I have fully charged it and left it in the garage for 2 weeks with out using it, it needs to be almost fully charged again. The maintainance free one that I had held a charge even if I did not use for a month. Is there a difference in the maintainance free battery and the add water battery? I just got back from Walmart and returned the other one because it did not hold a charge. They weren't too happy with me, but I explained my case and I got another "add water" battery. It is now charging up in my garage, so I will see how this one goes. Has anyone had this experience with these batteries? Any insight or suggestions are always greatly appreciated. Thanks!!!
