Hi folks,
My HP-35S I bought new in nov' 2007 and barely used since needed some fresh batteries to power on today! (Not a problem of contrast setting, I checked this).
My question: did you guys notice that the lifetime of the two CR2032 cells was that short in this calc?
Just as an information: my 26 years old CASIO fx-602P needs much less similar batteries. I don't remember when I bought some new, but it's much more than two years ago!
Any opinions appreciated.
Kind regards.
Jean-Michel
