Hmm, Are the battery contacts clean no residue left on them? It is possible that it leaked into the pens circuitry, and I have no idea if that could have caused permanent damage (if the acid is corrosive) or it just needs to be cleaned more thoroughly.

Vinegar and using a Q-Tip should help in removing battery acid from a leaked battery. I have no idea on how to open that pen. I would try cleaning the surfaced where the battery connects with vinegar and a Q-Tip and replacing the battery with a new one and see what happens.

If there are no visible screws to take apart the pen then you have to be rather careful, as it may be held together by some plastic clips. You may just be better off buying a new pen.

The battery you were using was that provided by the manufacturer?
