I replaced the battery in my 80 year old mother's '93 Gran Prix, which
she putts around her small town in. It was an Interstate battery, and
when I removed it I was surprised to see the date: the month was June,
and the 'year' digit was 6, indicating -- so I thought -- June of 2006.
But I was quite sure she hadn't replaced the battery in it in the last
year, and she had no recollection of it either -- nor could she find
any reciept for a battery with all her other car reciepts. Plus it
looked older than 1 year anyway -- it's located under the washer tank,
and the way she putts around a 1 year old one would still look new.
Her local service station guy (Interstate dealer, whom she's known
forever) was sure that the battery was way older than that also.
Could that battery actually have been installed in June of 1996 and
lasted 11 freakin' years? From what I've seen most people never get
much more than 5 or 6, and usually less.
I'm pretty sure that battery actually is 11 years old. My question
is, if it's even _possible_
for one to last that long, why don't the
other 98% of them last even half that?
