How do I check the battery voltage in an Audi A2?

I recently purchased a used Audi A2 and I want to make sure the battery is still in good condition. How can I check the battery voltage to see if it needs to be replaced or recharged?

To check the battery voltage in an Audi A2, you will need a multimeter. First, turn off your car and open the hood. Connect the black multimeter lead to the negative battery terminal and the red lead to the positive terminal. The voltage reading should be between 12.4-12.6 volts for a fully charged battery. If it is significantly lower, then your battery may need to be replaced or recharged.
