The HP-35s has always had a problem with battery drain. There are several threads about this topic on this forum. If I remember correctly Katie Wessman has solved it by replacing a potentially leaking capacitor. However this "rapid" battery drain has always been a matter of months (I have one HP-35s that lasts about two months, another which lasts for half a year) and not days. Yours must clearly be defective!

I'm going to look to see if I find that thread you say, and learn first how to open the HP 35s without damaging it, and then how to replace that capacitor. I have a soldering station and some things, but it is scary to damage it.
