RE: HP-34C external battery charging
I "recycled" a worn out hair cutting machine that had 2 AA shaped rechargeables inside, positioned parallel and is fed from a 3V DC charger. This way I can put a battery pack (cells connected permanently) inside for recharging.
Operating a spice from the original charger without a battery installed is no good idea in Spices.
