or mouser... ;-)
but what if he isn't good with the solder iron? Jon's suggestion to take in for service would rule...
I learned a few times myself not to give out too deep a suggestion some will attempt that and have bad results... reversing the capacitor or not even knowing it's polarized, too hot a iron or leaving on the track for too long, wrong type of solder, wrong value ( you know, it's just a few numbers off..)
I do think you might be right and not one of the chips that is doing the drain...
mileage may vary...

Subject: RE: [AN1x] AN1X Battery dies after 1 month HELP!!!!! Service Guide anyone?
This is almost certainly a defective (leaky) capzapitor in parallel with the
battery. Capacitors leak when they're brand new and it gets worse from
there. They'll eventually short out but that takes a good long while.
I don't have an AN1x (I have a PLG -- the easy-teenage-new-york-disco
version of the AN1x) so I can't tell you the location or PCB markings, but
it will almost certainly be an electrolytic capacitor of substantial value
(10-100ufd) and electrically parallel to the battery.
These parts are cheaper than dirt (good dirt though) so you can't really go
wrong replacing it as a test.
All battery-backup systems like this work the same way, so this advice will
also work for your PC's motherboard, your Minolta X700 happy-snap 35mm
camera, etc.
If someone will put up an accessible hi-res photo of both sides of the
board, I'll tell you the most likely candidates. They're REALLY cheap at
digikey or jameson, so it won't break your wallet to replace ALL the nearby
electrolytic capacitors with new matching parts.
