Spice chargers - Stephen Vater - 03-19-2005 I've recently been attempting to revive my 34c after many years in storage. I've acquired replacement battery packs from Digikey (they were great to deal with!)as recommended by Katie Wasserman's article in the museum (the part number has changed from p253-f021 to p229-f021, by the way). The calculator works as I remember, and passes the self test. Re: Spice chargers - Mike T. - 03-19-2005 I've owned the HP32E, HP33C (sadly now broken), and an HP34C and the chargers appear to be inter-changeable. Re: Spice chargers - Vassilis Prevelakis - 03-19-2005 My advice is to avoid connecting a charger to your calculator. Just charge the batteries with an external battery charger. You can get the HP external battery charger for the Series 30 (which is compatible with the adapter you have) on eBay. Of course any battery charger will work (even cheap ones). You can remove the batteries from the pack to insert them in the charger, or modify the charger to accommodate the HP battery pack.

Re: Spice chargers - db (martinez, ca.) - 03-20-2005 The "e" series can use either the a or b model charger. The "c" series needs the b model and can not use the a.
It sounds like your charger may have lost the springy tab in the center. In any case; if i was you i would use slightly used alkalines or charge the rechargables outside the calculator. Even with a good plug the batteries themselves can have itermitent contact and if this happens while charging it can fry the calculator.
