Last year I replaced the ordinary lead acid
battery in my tractor, it was 13, almost 14 years old and it would still crank over the diesel engine but it was starting to feel weak. In all that time I never added water or even checked the level. We typically get 7 to 8 years out of lead acid batteries in all the cars and trucks. I don't think we have ever had one last less than 4 or 5 years, and we never check the water level. AGM batteries cost about twice as much as regular lead acid batteries so they would need to last at least twice as long to be cost effective, although they can be mounted sideways or upside down if there is a need for something like that.
