What type of battery does the Audi A2 use?

I'm curious about the type of battery used in the Audi A2. Is it a traditional lead-acid battery or a newer lithium-ion battery? And can the battery be easily replaced or is it more difficult?

The Audi A2 uses a 12-volt lead-acid battery, which is a more traditional type of battery commonly found in cars. The battery can be easily replaced and can be found in most auto stores.

The Audi A2 actually uses a combination of a lead-acid battery and a lithium-ion battery. The lead-acid battery powers the starter and lights, while the lithium-ion battery is used for the electric functions and accessories. Both batteries are easily replaceable.
