HP 18C Battery cells



#3

I still have a calculator HP-18C Business Consultant. It need 3 N cells but I need to know the voltage of each one of them.... 1.5 volts? 9 volts?
Please, help me.

The "N" cells are 1.5V. They are VERY close in size to a 12V battery which will turn your machine into toast.
