UPDATE: Been running her hard over a month now and no signs of anymore problems with battery....even my custom mount is holding up well.
I did take this issue up with the dealer the next time I went in there, and at first, they just offered to replace the battery "like for like"....no way was that going to happen!!!! That Optima deep cycle is doing just fine and not going anywhere...lol. Since I had purchased the JD replacement parts from him, we finally mutually agreed on some reimbursement based on what receipts I had etc. I have no complaints with them and I'm happy. I just hope my post helps someone else to catch theirs before anything major happens. It's amazing how fast that acid will eat up that stamped metal.
