I bought a Optima red top about 20 years ago. That battery has been in at least 8 cars and at one point sat in a shed for two years and didn't discharge at all, still in a daily driver.
I bought another about 3 years ago that is still working great. Then last summer bought another that died after one winter, I think I left the dome light on for about 2 months, it was switched on when I put a new battery in the car. This battery would not take a charge even with the parallel trick. It was swapped out at the store no hassle, did not even ask for a receipt.
I think they are great unless you completely drain them, that seems to ruin them. Our local auto parts store will swap them out without question for 3 years.
