Yep. I normally use a solder sucker (cheap from Maplins I think) to get the 
bulk of the solder out; for a good quality PCB and soldering job the chip will 
probably come out with no damage caused.

If it's the battery that's gone, can't a new one be fitted? I know they're 
sealed units, but for most types if you know where in the module the battery 
is the casing can be removed and the dead battery disconnected, with a new one 
put in its place via flying leads. Details of where the battery is in this 
particular module are probably available via Google...

(I've not been following the thread, so apologies if that one's already been 
covered :-)

cheers
