Battery removal

[Gaidos, A.]

 All,
I replaced my battery in my 90q20v over the weekend and was expecting to
reset my clock and radio. To my surprise neither the clock or the anti-theft
on the radio changed.
 Just how long does the memory last with the power disconnected?
Thanks
Anton
BTW - please go vote for my wife Carol everyday. She's at
http://gaidos.got.net/Carol's (updated with some nice pics)and the contest
is at http://baywatch.citysearch.com/bayarea page 4. Look for Carol of
Scotts Valley. She really needs a lot of votes to make it to the next round
