📋 What we found
For your Audi A4 B5 1.8 we found 4 compatible batteries. This list includes 1 Start-Stop battery and 3 conventional batteries (non Start-Stop).
⚡ Battery type for your vehicle
✓ Your Audi A4 B5 1.8 does not need a Start-Stop battery. The conventional ones shown fit your vehicle and are the most affordable option. If you want a higher-quality, longer-lasting battery, you can also fit an EFB or AGM as an upgrade — they are fully compatible and last more years.
🔋 Technology (AGM / EFB)
✓ All Start-Stop batteries in the list are AGM. If your current battery is AGM, this is the right replacement. If it is EFB, an AGM is also a valid upgrade, but on cars with battery management (BMW, Mercedes, VAG group…) it must be registered and coded for the new technology with a diagnostic tool; otherwise the car keeps charging it as an EFB.

Frequently asked questions
- Yes, you can install a higher capacity (Ah) battery as long as the physical dimensions fit your Audi A4 B5 1.8 battery compartment and the positive terminal position matches.
- The Audi A4 B5 1.8 requires a battery with the correct capacity (Ah) and Cold Cranking Amps (CCA) for this engine. Compatible batteries offer 70-77 Ah, 680-780 A (CCA), 12 V, case H6/L3, conventional flooded technology. Browse the compatible battery list below.
- The exact Ah rating for the Audi A4 B5 1.8 depends on the vehicle's original electrical consumers. Compatible batteries offer 70-77 Ah, 680-780 A (CCA), 12 V, case H6/L3, conventional flooded technology. Use our finder for a precise recommendation.
- With normal use, a battery for the Audi A4 B5 1.8 lasts 3–5 years. A healthy alternator and avoiding deep discharges significantly extend battery life.
- You need the make, model and engine. If your car has Start-Stop (the engine switches off at traffic lights), it needs an EFB or an AGM battery, depending on what it came with: if it has an AGM, fit another AGM; if it has an EFB, another EFB or an AGM. On cars with battery management (BMW, Mercedes, VAG group…), moving from EFB to AGM requires coding the new battery. Without Start-Stop, a conventional battery is fine, or an EFB or AGM if you want a longer life.
- A conventional (lead-acid) battery is for cars without Start-Stop. An EFB is a reinforced conventional battery for basic Start-Stop. An AGM offers the highest performance and is fitted as standard on cars with advanced Start-Stop, regenerative braking or high electrical demand. Replacement rule: an AGM only with another AGM; an EFB with another EFB or an AGM; a conventional battery with any of the three. Never move down in technology.
