I dont think there are any cases that specifically have a spare battery spot. however, you can try checking into these cases --you can put the spare batt in a pocket in that:

Also check out this link for a thread that has a quick lookup for lots of cases that will fit the Axim:

I personally chose the vaja case (hoping to get it soon--i'm anxious) cuz of the quality, and I have a fairly large purse to put the rest of the stuff.
As for the Dell case, cut out the thing to put the axim in and use it to store your keyboard, screen protectors and cf cards that have adaptors on them (modem, IR extender, SM-CF adaptor, etc). Its a tight fit, but it works great.
