Hello,
So you have the original battery pack ?
If so, it it quite easy with a cutter to open the old one and replace the original dead batteries with 2 AA rechargeable batteries.
Fiding a woodstock battery pac is not only difficult, but if successful very expensive.
Don't forget that woodstock calcs might fry if connected on the power supply without batteries !

Why do you believe it needs 2 * 4V batteries? Every Woodstock (HP2x) series machine I've repaired runs off a 2.5V (or so) battery pack consisting of 2 AA-size NiCd sells in series.
If you have the oriignal battery pack, you can carefully cut it open, extract the original cells and put new ones in. If you don't have the original pack, you'need to find one, etiher working, or to be rebuilt. As a general comment, _never_ throw out old HP calculator battery packs -- the plastic housing, and some of the metal contact strips are needed to rebuild the pack.
