Hewlett Packard 3x vintage battery pack HP 82033A 2000 USA Mexico

From HP / Hewlett Packard, the maker of high tech programmable calculator (and a lot of other high grade stuff) come these 2000’s made battery packs. These are hardly used if any HP 82033A Battery packs and may still work or be a great basis for rebuilding. These were made to be used with the HP 82143A thermal printer and the calculator from the Topcat series (late 1970’s) like the HP 91, 92, 95C and 97.  Price is for all 3. They are clean and has minimal signs of use. Do check the attached video to learn all about the history of the HP calculator.
