if you're askig about the Seido regular surface w/the ext battery and back that comes with it, the answer is no. The two pieces of the case will not snap shut. I believe they now mfg a Surface intended for the ext. batt.
When I crammed the extended battery in with my standard battery cover, I can confirm that the Seidio surface case fit fine. However, I broke the surface case trying to open it back up. So I don't see this as an option unless you are not going to switch out batteries.So it works of you cram the extended battery with the stock cover?
