HP 50G question

[ijabbott]

I bought a cheap, "new old stock" TI-89 Titanium where the alkaline batteries had leaked inside the blister pack. (I can't remember if the batteries were also wrapped in cellophane or not.) It didn't do any permanent damage other than the inside of the packaging and the outside of the calculator being covered in magic pixie dust. (The pre-installed, lithium memory back-up battery was also dead, but hadn't leaked.)

EDIT: I forgot to mention that the battery leakage also stained one edge of the pages of the manual, but as the pages are coated and tightly bound, it didn't penetrate into the pages.
