Well we’ll see I guess, I’m coming up on 3 years. When I bought the truck, it had an Everstart in it, the lower 650 cca. It went kaput a little over its 3 year warranty. I can’t speak for how it was maintained for its first 2 years in VA. I could get 6 years out of this 800 cca one for all I know. I do occasionally maintain it on my MotoBatt Dual Bank Charger.3 to 4 years, that's still really short compared to what I get with the same Walmart battery.
