Yes it does, on the 2nd line it says "rechargeable lithium battery and charger" http://www.legoeducation.com/store/detail.aspx?pl=6&ID=1303&c=0&t=0&l=0

It also comes w/ an extra touch sensor as well as converter cables for using legacy sensors (those from RCX system).

I'm almost certain http://www.legoeducation.com/store/...=1467&c=1&t=0&l=0&bhcp=1 is the same as the above, just the software (which by itself costs $49. That software is NOT the same as the software for the NXT brick. THat software is called NXT-G. the plane old NXT LEGO ed kit Z979797 for $260 does NOT come w/ software since they are assuming a site license. You can buy the single user software license of NXT-G for $69.

Confused yet?

that's hwy I say call your local LEGO Ed rep and have him/her send you a catalogue...much easier.
