Bought a replacement battery at Sam's Club

I'm hoping you made sure the vent hose was hooked up to the battery...? You just don't want it venting in the cabin corroding up the stuff back there. As long as you got that hooked up and the AH and RC rate match the OEM you shouldn't have a problem.

The new battery came with a nice vent tube and an optional extension in case it wasn't long enough. The new battery vented in the middle, so I did use the extension and made sure it vented properly. The new battery had 850 CCA and has a considerable warranty - 36 months full replacement 120 months prorated. It seems like a solid deal to me. FWIW, they also stocked the 3.0 battery as well.

Does anybody know the AH (Amp Hours) and RC (Reserve Capacity) rating of the stock battery (I'd be interested in the 4.4l; not sure if there would be a difference between its and the 3.0's)? I've been searching, and I can't find it. Is it stamped somewhere on the battery?

I called Everstart, and the guy told me he's pretty sure the RC on their MAXX-49 is 140, and he thought the AH was between 70 and 80, but he was going from memory, as he didn't have access to a spec sheet. The RC on a Duralast 49-DL is 155, but its AH wasn't listed. Thanks.
