[Thinkpad] Extended battery on X31 & port replicator II ???

[Jon Kelly]

Does anyone know if the extended battery
(02K7041<http://www-131.ibm.com/webapp/wcs/stores/servlet/ProductDisplay?catalogId=-840&langId=-1&partNumber=02K7041&storeId=10000001&dualCurrId=73>)
will still allow my X31 to dock in the PR II?  I can't find a picture of
that battery that includes the underside.

I've got a slowly weakening main battery, and I was thinking that the
extended battery might make more sense than buying a new main and having to
juggle batteries. (I plan to squeze a few more cycles out of mine before
disposing of it properly).
