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

I've noticed my Audi A2's battery seems to be draining faster than usual. Is there a way to check the battery's health on my own or should I take it to a mechanic?

To check your Audi A2's battery health, you can use a voltmeter or take it to a mechanic. If the voltage reading is below 12.6 volts, it may need to be replaced.

You can also check your Audi A2's battery health by using a battery load tester. This will determine if the battery can hold a charge under load.
