Speaking of duds I just got a Die Hard Platinum AGM for the wife’s 2017 Ford Escape got it all put back together and nothing, all the lights were super dim when I opened the door and only a few dash lights turned on with the key on, go to crank and immediately everything goes black, I pull that battery and take an extension to touch both terminals together and not even a spark, I take it back to AAP they test it and it test out at 30 CCA and 10.9 volts and the battery was made October this year, they take get me another one and test it and this one tested at 1000 CCA on a 760 CCA battery needless to say my 30 minute job took 2 hours
