How can I check the battery health on my Audi A2?

I recently bought a used Audi A2 and I want to make sure the battery is still in good condition. Is there a specific tool or process I can use to check the battery's health?

You can use a multimeter to check the voltage of the battery. A healthy battery should have a voltage of around 12.6 volts.

Another way to check the battery health is to test its cranking amps with a battery tester. This will give you an idea of the battery's ability to start your car.
