I am not a casual user, my son and I have about 20 pieces of equipment and commercial vehicles, we use a lot of batteries.


What I've found over the years is that vehicle battery life specs are optimistic, presumably best case scenario. I've had so many batteries go dead with less than a year left on their "warranty" that for the past several years I've just bought "5 year" batteries from reputable companies with the plan to replace them after 4 years, not bothering with the "warranty." Less stress that way.
