Audi A4 Alternators

Why buy Audi A4 battery & charging parts from Eurowagens

• OEM Audi A4 battery and charging parts from Hella

  OEM Audi A4 battery and charging parts from Hella alongside quality aftermarket alternatives that match OEM performance at a lower price, each priced apart on the product page so budget and the job decide, not guesswork. Later A4s with start-stop technology and more onboard electronics need an AGM battery rather than a standard lead-acid unit, and the correct capacity, measured in amp-hours, varies by engine size across the range. Fitting an undersized battery, or the wrong battery type, is a common mistake that can leave the start-stop system disabled entirely.

• Every Audi A4 battery checked against your exact fitment

  Use the vehicle picker above, or our filters, to narrow the range down to your exact A4 generation, year and engine before you buy — the picker and filters are the only in-page narrowing available, so confirm whether your A4 needs AGM or standard, and its correct capacity, rather than guessing. Not sure which battery type or amp-hour rating your A4 takes? Rather than guessing from a parts diagram, send your registration or VIN through Find My Part and our team will confirm the fit and quote you directly before you order.
