The same thing happened to me after about 3 months. The battery is soldered
in, but it is easy to replace. I bought a battery holder of the appropriate
size and de-soldered the old battery and replaced it with this new holder.
Be sure you get the polarity correct. Luckily the holder will fit
in the space provided overtop the IC. I don't remember the details
on the holder or the battery #, take the battery to some electronics place
and ask there. I got my stuff here at Fry's - our local electronics
supermarket.
