12v battery cell
What voltage should a 12V battery read?
Then, connect the red probe to the positive terminal of the battery and the black probe to the negative terminal. Once connected, read the display on your multimeter. A fully charged 12V battery should ideally read around 12.6 – 12.8 volts. If it reads lower than that, it might be time for a recharge or replacement.

How Many Cells Does a 12 Volt Battery Have?
The nominal voltage of a 12-volt battery refers to the voltage per cell. Most lead-acid batteries have six cells, each with a nominal voltage of 2.1 volts, which adds up to a total battery voltage of 12.6 volts. Lithium-ion batteries, on the other hand, can have different nominal voltages per cell, depending on the specific chemistry and design.
