Very nice aaa battery pack for Classic Calculators

[Waterhosko]

Yes I'd be glad to reduce costs for international shipping. Also if I send the cases with no cells I can even drop shipping costs more. Say $5 shipping.

I am still curious about the voltage issue. I have a friend who heard that alkalines will ruin the calculators. He does not know for sure this is true. I have measured voltages on charged battery packs over 4 volts. So I'm not at all convinced that alkalines will hurt the calculators.

Does anyone know for sure?

I have been running my calcs: HP-45 and HP-67 with no problems, on this case with AAA alkaline cells.
