I'm not sure what MIB means..."mint"???

It's unlikely that enough people will ever care about about those models for it to make any difference what you do with them. The same goes even for useful models like the HP 48SX and GX...the market is flooded, and their 50G replacement is very inexpensive brand new and a far more capable machine. Few will ever care about the 48-series because of their commonality and limitations.

Now, if the machine is a highly-desired gem, like a HP 42S, then there's a decision to be made. The short-life alkaline batteries that HP installed in the Pioneers would die within about three years of non-use. They need to be removed! That's what I did with the NIB Pioneers I bought in 1997 (including two 1993, never-opened, batteries-deader-than-a-hammer HP 42S units). One of those units is still otherwise unmolested.

But for an HP 33S or 35S...or almost anything that HP (or TI or Casio or Sharp, etc.) has made in the past 30 years? No one will ever care about them once some replacement comes along. Exceptions? Casio scientific calculator wristwatches and 'credit card' scientific calculators...only because they were almost unique, somewhat useful, and were abruptly discontinued without equivalent replacements in anyone's product line. The same hasn't happened in HP's product line except...er...the HP 42S!

If it were me, I'd pull the batteries after about five years if the unit is in a bubble package that must be destroyed to open. I'd do it sooner if access requires only removing shrink-wrap cellophane.
