Set it to DC Volts and red to POS. and Black to Neg. There ain't no Rocket Surgeery involved.
Why would it read 1.2 V on a 1.5 V battery?
(There ain't no Rocket Surgeery involved.Had a VP at my old company that said Brain Science, thinking she said it right, during a meeting with all the managers and other higher ups. )
NiCad and NiMH batteries develop about 1.2V per cell. Regular alkaline develop a bit over 1.5. Lead-acid develop about 2V.

Cause why your writing the thread. They are going down/gone
1.5 showing 1.2V recycle time.
Set the MM to DC and place the probes on the respective polarity.
To know capacity of the charge you'll need a battery tester which will add a load to the reading and tell you that battery's state.
Poorly.
meter set on DC ..
check for appropiate voltage range if the meter isn't auto ranging..
leads to the battery...
get a negative read.. switch terminals..
but you'll only get voltage and not RW status of the battery...
for that you need a battery checker..
Life is not a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside, thoroughly used up, totally worn out, and loudly proclaiming
WOW!!! What a Ride!
Forget the primal scream, just ROAR!!!
You can see if the voltage is correct but it won't tell you if it's capacity is diminished. Connect it to a light bulb and note how fast it goes out. Use the multi-meter in series, set to measure Current. The battery is rated in Amp-Hours and the capacity divided by the current should indicate the time until it falls to a specified voltage. An old battery can read perfectly good with a voltmeter but the light can go out immediately.
