After a few slow starts I replaced the battery in my beater G6. The auto craft gold was in use for 6 years 1 month I usually change at 5 years but lost track of time. Put in a AC Delco battery that's been in my storage room in the basement for 2 years on and off a trickle charger the whole time. When I leased the traverse 2 years ago the dealership gave me a $100 voucher to use towards accessories. While the salesman was showing my wife the truck I went to the parts department and got the battery free for the G6. I'm surprised I got that much life out of the auto craft. I'm just wondering how long AC Delco will last since it sat around for awhile and not always on a trickle charger.Also the Auto craft looks good no leaking or swelling.
