As you can see I replaced both of my separate vehicle batteries with Optima Red Top batteries in 2024 only a few months apart.. They are now both sitting on my shop rollcart because they both rated a dead cell with resistance off the charts with all the warnings and flashing lights that come from a $5000 battery test bench. Worst yet my O'Reillys will not warranty the battery nor will they take them as cores for the new batteries I was forced to purchase (Super Start Platinum Agm). Their reasoning is they still need a physical receipt from purchase...when they can even show me in their own system where I bought them. So my anger is flashing two-fold. Screw O'Reillys for choosing to stay stuck in the early 2000s and screw Optima for changing whatever they changed to make a battery that used to literally last a decade to a battery that barely made it two years under average use.
The Super Starts I went with I only purchased because they were only $200 each (with my shop discount). But never again will I pay $400 for "premium" battery brand like Optima if it can't outperform the store brand.
And before anyone asks both batteries came out of a 2002 Grand Marquis and 2004 Yukon. Neither have voltage leech nor voltage drop (I checked). They're old so they don't have fancy tech that can be blamed. I mean I swear they could both stay running off a potato (not really but you know what I mean). And yes they are daily driven in a mild climate so weather and time between starts shouldn't be a factor.
