GJAC says..."When I input both numbers in the Costco web site, 245725 and 850284 both say invalid item number. My local Costco in Ct. does not carry them either in battery section or tire section."
Sorry that didn't work out for you. I got those numbers off the internet by searching for COSTCO GC2 6V batteries... I just learned today that INTERSTATE Batteries just bought out the KIRKLAND GC2 6VDC battery line and adding that to their line of batteries. I see they have a pretty good price on them too from the list I sent along haha...
I've never been to a CostCO store before or even a SAM's CLUB haha...
I am getting my GC2 Trojan T105s from a local golf cart dealer here locally...
You can purchase such batteries on-line but when they are shipped they have to go to a business address like an automotive repair shop etc... Then you can go to the shop to pick them up... They can't come to your house using UPS or FEDX I guess...
