Spec on Costco Batteries?

Just picked up a pair of the Costco #245725 6v batteries, $84.49 here in Louisville. The batteries themselves have nothing but the cheesy "golf cart" label on them, no specs at all. The shelf tag said 208 aH, but a lot of online sources say the battery is rated at 220 aH. Anybody know what the real rating is?

I was looking hard at the Interstate GC2-XHD at 232 aH, but couldn't justify them at $153 each.

Guy at Costco said their batteries are also made by Johnson Controls, same mfr for the Interstate brand.

Some previous threads on this have shown that those are indeed 208, which is one of the standard "sizes" Interstate used when they had US Battery 6s called U-xxxx. The U-2200 is 232, the U-2000 is 216, and the U-1800 is 208 IIRC. As these have different weights, you should be able to confirm which "size" you have by comparing it's weight with those US Battery sizes in that company's table on their site.

The GC2-XHD (made in Mexico ISTR) replaced the U-2200 for Interstate a couple years ago but still retains the 232AH spec.

The 220 size ISTR appears in some other stores in other parts of the USA where they have a different source of batteries by region. I forget who makes those 220s
