Gents to my pleasant surprise the battery on my 2005 97X died today after 6yrs 11 months of service. That I think is a record for a SAAB battery here in FL. It was funny look at an SAAB OEM battery knowing that it is now a part of History.
Congrats! Yes, that is a good length of time for that battery to last. Actually I think it is harder on batteries to be in a cold environment like up here in WI during the winter, but most OEM GM batteries last about 5 years for me.
The exception was the battery in my '98 Buick Riviera when that died a couple years ago it would have been almost 10 years on the clock! I'm quite sure it was OEM as I knew the original owner and had all the receipts of anything ever done to vehicle.
That battery was under the rear seat and it was huge! About 1.5 times the size of any SUV battery. I don't know why!
