Batteries go bad from usage as much as time. At 60,000 miles I would replace
it. Warranties are prorated on batteries so you probably won't get any more
off a retail price than you could find on a sale. As was mentioned check
your documentation check prices where your battery is sold.....
I would put a new one in, but no need to buy it at a dealer. I think
your vehicle takes a group 35 size battery. If so, the Napa Legend 7535
was the top rated battery in that size in Consumer Reports' recent
battery test. It should cost around $60 at your local NAPA store.
