re: the -8,888,888,888 changing to -9,999,999,999 problem. every time this happens; add 1,111,111,111.
Seriously; running on any kind of battery other than the hp battery pack IS a very good idea, as long as you don't reverse the polarity. In addition to what Renato said about the charger; if the batteries are not making good contact when you are using the charger then you can fry the calc. That means to never let them go completely dead, so you know that you have a good battery connection before you plug in the charger.
It's sad that hp made such a bad recharging system. As a collector i want to have a charger for each calc but as a calculator user i don't want to plug the charger in.
