Can anyone tell me how to use a multimeter to test a AA battery?

Ok let me throw in the electricel answer here. To do it correctly you need a load. If you can put it in your radio or calculator etc., place a probe on each end of the battery while the radio is playing. You should be 1.4 volts or higher. Duracell is the best with plenty of brass ba--s.
That is why hospitals use them in all of the monitors. The old wifes tail about the new fangel digital cameras will blow up if you use duracells cause they are too hot. All my digital stuff uses factory type lithiums. The simple test I use is take two AAs and put them in your pocket flashlight. If it is dull--- change them. Jeffcat

Hi Josho,

When testing any battery via voltage measurements you have to let the battery stabilize for 12hrs or so or you'll get a false reading.

By stabilize I mean at rest or not being used as you have to give the chemical reaction time engough to complete.

I would take the battery to a friend that has an accurate meter preferably a digital one and see what voltage the battery has.
I think your meter might be out of spec.

I usually throw the batteries away when they hit 1.4 or 1.35 volts DC

I was really trying to find which setting to use and I think you have answered my question. On that scale the new is reading about 1.6 and others that I thought might not be very good were under the 1.5. Even though it doesn't seem like much difference to someone like me - it is a big difference in performance. Thank you

If it has not been in use recently, and is in good shape, it will test at a little over 1.6 Volts, a little about it's "nominal voltage" of 1.5 Volts.

That's about all the information you are going to get with a multimeter, as a REAL battery tester, even for a little battery like this, throws a load on the battery while testing it, and a run-of-the-mill multimeter won't have this function.

It is a GB instrument GMT-12A multimeter. Did you tell me to set it on the smallest DC V setting? That is a 10. The battery indicator on the bottom of the screen barely moves up on a brand new battery. Other settings are DC ma and OHM X1K. The new battery is reading replace and I KNOW it is brand new.

It wouldn't be the first time a new battery was bad. Try connecting the battery to a single cell lamp. If it's good, the lamp will glow brightly. If it's weak you'll know it. Your DVM does not put a load on the battery.
