Generally I guess one can expect around 5 years on a battery. Give or take. Depends on how hard its pushed,like a lot of other things.
MY current battery is a good battery,but the posts can get pretty heavy deposits of acid/electro-chemical reaction stuff on
I would suggest cleaning your posts and connectors at least once a year (twice would be better)
and putting that battery grease on and around the connections. That build-up on the battery posts causes resistance and makes your battery and alternator work harder which will obviously reduce the life of both.
Also , did the battery just die without warning ? Did you have to recharge it often ? Did you run aux equipment with the car not running often ? Heavy current draining equipment with or without engine running ?
