Assuming you have pretty much a 12 month mowing season.
Mine is 3 1/2 years old and won't hold a charge for a week.




I have found it can be anywhere from about 2 to 5 years. They could be
like car batteries, some cost way less than others and hopefully the
more expensive ones will last longer. If you get 3 years out of the
average Walmart battery you are doing good.

If you have one that can be checked, do you look at the water level in
it very often ?

Water is good, terminals clean, charging system working OK, zero
current with the key off.
I am guessing it may just be a bad battery. A few minutes on the
charger and it starts, mow a while and it seems to be charged. (amps
go down). Then it is OK for a while.

BTW I am not sure why people trash Walmart batteries. Johnson Controls
makes them, along with a bunch of name brand batteries. The one in my
truck just failed (would not hold a charge for 3 few weeks, as often
as I use the truck), after 7 years.


Johnson Controls makes some of the best (and the worst) batteries on
the North American market today.
Lawn tractors are a VISIOUS environment for a battery - lots of
vibration. An AGM batterywithstands the vibration much better and it
MAY be cost effective to go that route.
