A 2 Ah, 18 volt battery will have more stored energy than a 2 Ah, 12 volt battery. 2x18 = 36Wh versus 2x12 = 24 Wh A 6 Ah 12v battery has more stored energy than a 1.5 Ah 18 volt battery. So for example an M12 hackzall with a 6AH 12 volt battery will yield more cuts than a 18V hackzall with a 18v 1.5 Ah battery.
Choosing power supply, how to get the voltage and current ratings?
Another issue with unregulated supplies is that the output voltage not only is a function of the input voltage, but will also fluctuate with how much current is being drawn from the supply. A unregulated "12 volt 1 amp" supply is probably designed to provide the rated 12 V at full output current and the lowest valid AC input voltage, like 110 V.
9V Battery Current Range
The range of current that can be delivered by a 9-V battery depends on its chemistry and quality of manufacturing (and design target). For example, a freshly made "Zeus 9V alkaline battery" can deliver 2.5 A of current (9.5V with 3.9 Ω load for 0.3s): With voltage drop of just 0.1 V, this make the battery ESR of 0.1/2.5 = 0.04 Ω.
batteries
For the Mohm range, 1 micro amp injected into the resistor-to-be-measured will produce 1 volt across 1 Mohm so this current is likely trivial compared to the current taken from the battery by the measurement system and LCD - if it''s an analogue meter this may take more current than an LCD.
