Note that the source of the "lot of 4" was a green waste disposal dealer, so the likelihood that they were in disrepair would be much higher than a random sampling of calculators.

I've given my main 50g significant use over the last 12 years, and it has no issues with keys, display, or painted faceplate/key labels. The only pending issue I foresee at present is the rubber feet, which are starting to show the tell-tale signs of "muck" where the adhesive is breaking down.

No one would argue that the construction quality of a 50g is as good as the prior models (up through the 48-series). But my 50g is considerably better built than my 30b. They're simply not in the same class.

Back to the original topic:

I have a 50g backup unit, and noticed not long ago that it had batteries which were already corroded (visible even without opening the package). That prompted me to open it and remove both the CR2032 and the AAAs. Fortunately, the AAA leakage appeared to have been contained by the shrink-wrap plastic in which the batteries were sealed.

If you have a working SD card, there should be no problem re-installing the included software at a later date (if that's even needed).
