Does it test a battery's maH?
If so, which of those 6 is it?
I don't think you can measure the capacity (Amp . Hour) of a battery without completely discharging it! I would be very interested to learn if there is a way.
A multimeter is just a tool, you have to devise your own testing methodology for whatever test you measure WITH this tool.
You can get close enough to meaningful results with mAH testing if you set up a constant current load (multimeter comes in here to measure that it's working as expected, constant current), down to 0.9V/cell (again multimeter, to determine when 0.9V is reached).
Another way to look at it is that instead of measuring a more common C/n current rate, you might instead measure the rate expected from your target device.
So in short, yes you want a multimeter to do such testing
measurements but no, you can't just hook the leads up and turn the dial to do it, it's not a multimeter feature to do the entire battery test itself.
