Why is there a difference between the voltmeter and battery test
My multimeter has a DC voltmeter, as well as a test mode for 1.5V and 9V batteries. I would expect that when I measure the same battery I would get the same result no matter what mode I use, but I have a dying 9V that reads as 7.62V on the standard voltmeter mode, 5.7V on the 9V mode, and because I was curious, only 1.8V on 1.5V mode.
Multimeter With Battery Feature?? : r/AskElectronics
When measuring a battery it should be done with a suitable load on it. The battery test modes apply a resistor across to be that load. Without a load you only have the unloaded voltage, which doesn''t tell you the whole story because the battery''s internal series resistance doesn''t have an effect, while in the loaded state the series resistance has a significant effect.

Can You Use A Voltmeter To Test A Car Battery? Accurate Step
When measuring a weak battery, the voltmeter provides a reading of the battery''s voltage, which reflects its state of charge. If the battery voltage is below the acceptable level (usually around 12.6 volts for a fully charged car battery), it indicates that the battery is weak and may need recharging or replacement.
