I believe I understand what you're trying to say here, but in my case that is simply BS. I know how to take care of Opticraps and like I said, my early models lasted several years with the BTs and all that when they were parked. Then when they gave up the ghost, they gave up the ghost. I felt I got good service from them so I bought them again. The next two soon turned into pure crap, even when taken care of the same way. I know it wasn't the cars because nothing changed except the batteries. Both wouldn't magically start having charging issues and then magically return to normal again when the batteries had been swapped out to diehard wets that actually worked.So many times you hear of people bad mouth Optima Red Top batteries and sometimes blame those problems on quality control or the fact they are made in Mexico. However, the real problem is they didn't read the instructions on how to take care of these batteries properly.
You'd think it'd be the other way around. When Opticraps were relatively new, a lot of people maybe would ruin them because they weren't used to the AGM style and had to get up to speed on their care. And the second go-round would be a better experience because they learned. Mine was opposite. All downhill. I'm not going to blame my bad experiences on QC or the fact they were made in Mexico. I don't know why they were crappy. But I am going to blame the fact that the last two Opticraps SUCKED and were a burden on my wallet and my time, thus negatively affected my enjoyment of my vehicles.
I'm not going to say every Opticrap is bad, but to me, a quality battery means I don't have to pay a premium price just to cross my fingers in hopes of getting a good one. Look at the bright side; it means there are more Opticraps are available for those who want them. You can have the ones I don't buy.
FWIW, I've got a diehard AGM in the 2010 Camaro (4+ years on that big b*st*rd) and a Delco AGM in the truck (2 years). Absolutely no issues/problems at all. #NeverOptima 🙂
YMMV
