Last weekend I obtained a pristine Sharp EL-211 for my collection. That device was offered in 1980. I paid two dollars at a church rummage sale. One end of the carton was slightly damaged. Inside I found the calculator, the instructions and a pair of AA cells. The calculator was still in its plastic bag. I don't think that it had ever had cells installed.

The two nonrechargeable AA cells are still in a sealed plastic bag. The nomenclature is Sharp UM-3(E)1.5V. There is no sign of leakage. Will this kind of cell last forever?. Are 32 year old never-used cells of interest to anyone?

I hate when you say that, makes me feel like an irresponsible big spender :-) Latest acquisitions here: 1 tall key HP-41C (~$170), 1 TI-57 (~$45)

Congratulations for yet another bargain!

Possibly the chemists at whatever company made the batteries!?

Hello, Gerson.

I found one TI-59 for R$50,00 (US$24,51) and one TI-57 for R$58,00 (US$28,43) both "almost" NIB, with perfect and intact boxes and manuals (in portuguese) and chargers, here in MercadoLivre [ our ebay :-) ]....

...I would like to find some HP's in same conditions and prices :-)

Regards

Hello Jamil!
