Well, I hate to admit it, but it's just about the end of the riding season here in SW Ohio. Once in a while we'll get a decent temperature riding day through the winter months, but they are few and far between. So anyway, my "07" Custom has the OME battery. I keep a battery tender on it whenever I'm not riding. I have had no starting issues, but I'm wondering how long should I stay with the original battery, before just going ahead and replacing it to be on the safe side. I'd hate to be out in the middle of nowhere, which is where I usually ride, and stop somewhere and not be able to get her started again.
