See followup message, seperate posting, on a revision level question.

Thanks for the responses on the battery type. In response to message #5 by Thomas Okken Message #6 Posted by John Horak on, 10:21 a.m., I never had an HP-42S lose memory when I changed the batteries - this is with 3 different machines, including my current one (1993 model, rev. In response to message #4 by Karl Schneider Message #5 Posted by Thomas Okken on, 7:22 a.m., I also have a newer design 42S from 1992 whose batteries I haven't yet changed. My older-design 42S from 1989 recently survived a battery change with memory contents intact. HP-42S have a problem of not retaining the contents of memory during battery changes - maybe a bad batch of capacitors was used, I don't know. Silver oxide lasts longer but costs more. They are interchangeable, but it's best to use the same chemistry (alkaline or silver oxide). Luiz and John Limpert have given more details, but the simple answer is, three of any type 44, 76, or 357 cells. The HP 12C features HPs traditional RPN (Reverse Polish Notation) entry system others are designed for people who prefer algebraic entry calculators. Message #4 Posted by Karl Schneider on, 3:28 a.m., Re: HP 42S - Battery Type and Constant Memory It's a silver oxide battery (lasts longer) and it has received good reviews. Message #3 Posted by John Limpert on, 2:24 a.m., The HP33s allows key in logic in RPN or algebraic input. Maybe some of these do not even exist, and even better models are available. The HP33s is a powerful 2 line display, programmable scientific calculator. In fact, these references are taken from the original HP15C Owner's Handbook, dated February 1984. For a higher current consumption (in case you plain to use the printer output constantly) you can try the Silver Oxide models: Eveready/UCAR 357, RAY-O-VAC RW42 OR 62, Duracell MS76, or others. They are the same as the National/Panasonic LR44, Eveready/UCAR A76 OR RAY-O-VAC RW82 all alkaline. You can use the same ones designed fot the Voyagers (HP10C to HP16C).

What kind of batteries does the HP42S use? The owners manual just says it uses 3 button batteries, and the 42S I recently acquired came without batteries, and I want to make sure I get the right kind.
