Why my wiimote's battery got hot??!!!

[theworldnot]

Hi,
Can anybody help? I really confused with the problem of my wiimote battery:
I can connect the wiimote with my PC and use GlovePIE029 perfectly. But the problem is the wiimote becomes very hot and the battery run off very quickly (around 30-40 minutes). And even if i didn't connect the wiimote with PC, its battery also runs off very quickly.

After I sync the wiimote with the Wii console again,the wiimote comes back to normal status(it isnt hot and battery stops run off).

Any body has encountered this problem before? I looking forward for your idea and help.

Many many thanks.
