I have an HP 82713A Plugin Module Simulator for an HP 75. The internal battery is almost dead and I have replaced the battery with a module that accepts lithium button cells ( 20 mm size ). I have the polarity correct and was wondering the voltage of the original battery. I think that the correct voltage is 3vdc but I would appreciate a confirmation on this before I install the new battery. The battery is used to retain the volatile memory of the simulator. The numbers on the original battery are :
3440
4-0482
Thank you,
