I have a bunch of small questions, mostly about batteries...
1) I've recently purchased an HP-19C and put in a new battery pack with NiMH 1850 mAh AA cells. Is it safe to recharge the batteries in the calculator? I've scoured the HP archives for information on this and it appears the consensus some time ago was that, yes, it was safe. I'm just looking for any updates to those opinions.
2) Same question for the HP-34C.
3) Any reason why a Woodstock would have problems with a rebuild pack using NiMH? I've tried a couple of packs/battery combinations and have gotten nothing. I know the batteries are ok because I can transfer them to another pack for a different type of machine and they work. I also know that the Woodstock calculators work.
3) Can you throw the HP "leatherette" cases into the washing machine? I have Voyager cases spraying the dreaded black powder and a Spice (fuzzy inside) case which stinks. Any experience here?
