I only got 2 seasons from my original battery, but I didn't charge it in the off season, and would drain it before I charged during the season. Last year I went to my buddy that owns an Interstate battery dealership in Valpo, and he hooked me up with a double sized battery... It's too wide to fit in the propaks I think, but it holds a charge twice as long as the normal batteries... I am going to try and take better care of this one and see how long it will last me.
