I have never had an issue with any Optima battery in over 20 years.
I have 2 vehicles and 1 tractor currently. All of them have Optima red tops in them. Currently the oldest one is 11 years old (wife's 4Runner), followed by a 5 year old one in my tractor, and I just put one in my truck last year. They work flawlessly down to -45F (not windchill) and I never have to charge one or try to keep it warm. My truck can sit for weeks at a time and it always fires up on the first try (now that it has an Optima). Tractor sits out in an unheated shop building all winter, no charger or battery blanket on it. It can always fire up after one cycle on the glow plugs, even after sitting for weeks at -40F.
My old Dodge powerwagon had a "blue top" (the combo one, for starting and rv draw deep cycle). It was still fine after 10 years in my truck in AZ.
I keep buying them because they keep working for me. If they didn't, I would toss them. I owe no loyalty to the brand, other than they keep working for me.
