Any of you recently replace a dying/dead Optima? I think the bluetop in my truck is slowly dying. It's not a sudden death like with a normal battery, but over the past few weeks, if the vehicle has not been driven for 2 days or more, the engine turns over very slowly, but still starts on the first attempt, as if it were very cold with a heavy-weight oil. FYI, temp is about 60F running Shell Rotella T synthetic 5w40. I was just wondering if the sprial gel Optima gradually degrades, unlike a normal lead-acid battery, which seems to suddently die. If so, I guess this is good, as you get some lead time to source a new battery?
