I'll have to check, but it is starting to die much faster than it used to. (checked... 90%)
But thanks to the whole debrick experience I've had, I've taken one of my Touchpads apart over and over... and it's not that hard to do but lots and lots of step to get to the hidden connector.
I had bought a spare battery at the time, so I should be fine.
The hardest part is to pop the clips without breaking them so to pop the screen off, then to be gentle to not do any damage to the cables.
The battery is really stupidly placed, in that you may have to take the whole bottom section apart to get to the connector.
OR you can cheat a bit by being a bit risky (At your own risks, but will skip step 17 to 27 of the ifixit guide (link below))
Instead of taking everything apart, once you see the battery, remove any tape or such that is holding it on this side, note that the battery is held in place by double-sided tape on the other side, so you will have to pull it off. Then once you have the battery in hand and only the wires (connector) holding it, by applying a bit of force on the board to lift the area where the connector is (on the other side) you can pull on the battery cables and disconnect the plug and get the battery out, Then get the new one replugged in the same way and be done.
But if you're doing to do this, be extremely gentle, and don't use a metal tool if possible, the last thing you want is to crack the board.
Once you've done it, you'll see that it's actually very easy.. I ended up doing it several times during my work on my Touchpad.
Between this and the risk of damaging the several other cables and connectors (much smaller), plus forgetting to do something, etc.... I consider it a decent risk if you're careful.
I did a simple graphic to illustrate the clips: http://i478.photobucket.com/albums/r...dgets/clip.jpg
Please note that there are several of these clips around the frame..
