The original cells for the HP35 were 3 times 1.2 volts.
New AAA batteries produce 1.5 volts.

1.2 volts is just the "nominal" ni-cad voltage, fully charged they are at 1.45 volts. 3 x AAA alkalines or primary lithium cells works great. I use this in the the HP 'Classic' series calculators I have and never had an issue.

Why not AA? I don't se any reason to use AAA. But I agree there is no problem with the higher voltage of the Alkalines.
