Bruce,
You can look at http://www.hpmuseum.org/collect.htm#diff
to see that they are "worth" about $86-$352.
You can make up a battery pack from generic NiCds, or you
may be able still to find some sold. (University Book
Store in Seattle had them last time I tried, which was
5-10 years ago.)
Have you tried reading a magnetic card? It is quite
possible the rubber wheels that transport the mag card
have "gummed up". Be careful with the cards; use a
"scratch" card the first try.
Email me offline if you need more info. I used to be a
pretty good HP-65 programmer, but it's been a while!

Ok, so I'm not a big calculator collector. ;-) However, I did pick up a
neat little box recently, one that I'd like to (a) find out, ballpark, what
similar units have been going for on the swap market, and (b), use it
myself for a while.
What I've gotten is an HP-65, in pretty darn good shape, in its hard case
with a bunch of the program pacs and all its manuals. I know I've got at
least one, possibly two EE pacs, a stat pac, and others that I've not
looked at just yet.
The batteries are dead, of course, so I think I'd like to get them
replaced at least. Are they generic NiCds or what?
Thanks in advance.
