Spec on Costco Batteries?

http://www.batteryfaq.org/ Generally tells you who makes what and is updated with regularity.

I was told Deka made the batterys I bought but they are 12volt and I also have a pair in the 6.7 Dodge with a Dura Cell sticker on them so to keep You thinking what are they or made by who??? never had a moment of trouble and dry camp a lot think they are good a battery as any other and all 4 from Sam's Club... But I check the water now and then add some but not a lot Bushman

I have the U-2200's now and they have done OK over the years despite being boiled have dry on a regular basis by the old WFCO converter. Water usage is much less and float charging much better with the new PD4660.

So Costco lists the weight at 63 lbs, which is in between the Interstate GC2-RD at 62 lbs and 208 aH and the GC2-HD at 64 lbs and 216 aH. The GC2-XHD is listed at 65 lbs and 232 aH.

I'm hoping that 208 vs 232 aH won't turn out to be an issue, but I am hoping that faster charging with the PD4660 and the fatter wires to the batteries will make up for that.

I would suspect that at this price point, they are the RDs and not the HDs but one can always wish....

These generally got good reviews so I figured for the money I would give them a try.

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
