The current after the battery voltage is changed is not large enough

I am not sure this is being answered that nicely. Nominal voltage of batteries like CR2032 is 3 volts, but the real measured voltage is normally over 3 volts. I just tested a fairly new functional battery and was 3.4 volts. Some Motherboards are very sensitive and 2.9

PC losing CMOS settings, battery shows 2.90v, is that enough?
