2014–2018 BMW M3 Battery FAQ's

Please read our FAQs page to find out more.

Do I need to register a new battery on the F80 M3?

Yes. The IBS/charging system expects a registered battery. After replacement, register type and capacity (AGM vs flooded) to maintain charging strategy and longevity.

Is a lightweight battery worth it on the M3?

A small‑case AGM or motorsport lithium drops ~15–20 lb, sharpening turn‑in. Choose appropriate CCA for your climate; lithium needs a compatible tender for storage.

Where is the battery located on the F80?

In the trunk from factory. For weight savings, choose a lighter battery rather than relocating—keep a solid tie‑down and venting for safety.
