Ok I am a little tweaked right now.... got in my trail rig, she started hard 'cause she hasent been run in a few weeks. Drive to Walmart batterys dead wont start. Get a jump get home, check the voltage about 12.5v at idle. Figure its a bum alt. jump it the next day to drive it to my shop. Amp gauge is pinned out at 60a+ (charging) Pulled the cables off alt is putting out 14.5. Battery is toast. This battery is a year old redtop, on a recreational seasonal vehicle. Optimas site dosent even tell what kind of warranty they have they say "consult your vendor for warranty info" Glad I bought it through summit. Between the shipping and I'm sure a prorated adjustment it probably wont even be worth replacing. I plunked down a extra $50 for this super battery and what the hell did I get out of it. Sorry for the rant but.... Does anyone else have optima problems?
