How to test AA and AAA batteries using a multimeter
Turn the dial to a higher voltage setting - Try the “200” setting in the DC voltage (V⎓) section. This will handle voltages up to 200V.
Check your connections - Make sure:
- The black probe is firmly in the “COM” port
 - The red probe is firmly in the “VΩmA” port
 - You’re making good contact with the battery terminals
 
Verify the battery orientation - Make sure you’re touching:
- Black probe to the negative (-) end of the battery
 - Red probe to the positive (+) end of the battery
