📋 What we found
For your Audi A4 B6 1.9 TDI we found 5 compatible batteries. This list includes 3 Start-Stop batteries and 2 conventional batteries (non Start-Stop).
⚡ Battery type for your vehicle
Does your Audi A4 B6 1.9 TDI have a Start-Stop system? It shuts the engine off at short stops (traffic lights, jams) and restarts it automatically when you release the brake/clutch. If your dashboard has an "A-OFF" button or an engine icon with a circular arrow, it has it.
How do I know if my car has Start-Stop?
What happens if I fit a conventional battery in a Start-Stop car?
🔋 Technology (AGM / EFB)
Do you know whether your car's current battery is AGM or EFB?
Check the label on your battery: if it says "AGM" or "VRLA", it is AGM. If it says "EFB", it is EFB. If it says neither, it is most likely EFB — though on cars older than 2010 it may still be conventional. If in doubt, go for EFB: it fits both cases (an EFB in a non Start-Stop car works fine and lasts longer). The mistake to avoid is the opposite: never fit a conventional battery on a Start-Stop car.

Start-Stop & high energy demand batteries
AGM or EFB battery for start-stop vehicles and for cars with high energy demand (many electrical consumers, frequent starts). More charge cycles, better charge recovery and longer service life.
Does your car have Start-Stop?
Start-Stop switches the engine off at traffic lights. If your car has it, it needs an AGM or EFB battery.
There are no batteries of that type for this engine. Try "Show all" or message us.

Frequently asked questions
- Yes, you can install a higher capacity (Ah) battery as long as the physical dimensions fit your Audi A4 B6 1.9 TDI battery compartment and the positive terminal position matches.
- The Audi A4 B6 1.9 TDI 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 B6 1.9 TDI 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.
- To find the exact battery you need, you need to know the make, model, and engine. If your car has a Start-Stop system (the engine shuts off at traffic lights), you need an AGM or EFB battery. An AGM battery can only be replaced with another AGM battery. However, an EFB battery can be replaced with either another EFB or an AGM battery, as the latter is superior.
- The standard battery is the conventional type. The EFB battery withstands start/stop cycles better. The AGM battery is the most durable and is mandatory in cars with Start-Stop and regenerative braking. Never replace an AGM battery with an EFB or standard battery.
- Use the search tool by selecting your vehicle's make and model. Our system automatically filters compatible part numbers verified by our technicians. If you have any questions, contact us via WhatsApp.
- All our batteries come with the legal guarantee provided by consumer law against manufacturing defects. If a battery has a manufacturing defect, it will be replaced at no cost to the user.
- Under normal circumstances, batteries usually arrive within 1 to 2 days of ordering. However, there are some cases where delivery may take a little longer: peak seasons (Black Friday, Christmas, etc.), palletized shipments, occasional stock shortages, etc.
- In mainland Spain and Portugal delivery takes 24 working hours if you order before 6:00 pm and the battery is in stock; for the Balearic Islands and other EU destinations allow 2 to 5 days. Batteries are shipped fully charged and ready to install.
- ⚠ Then you need a battery designed for Start-Stop (EFB or AGM). We have hidden the conventional batteries from the list: fitting them in your car would ruin the battery within months and could damage the alternator. The batteries below are built for the frequent charge/discharge cycles of Start-Stop. 💡 Great. You can buy either a conventional or a Start-Stop (EFB or AGM) battery: a Start-Stop battery is perfectly valid in a non-Start-Stop car and is actually more robust (longer life, better cold-start performance). It is just a bit pricier. On vehicles older than year 2000, an EFB is preferable to an AGM: legacy alternators charge at a fixed voltage without temperature compensation, and an AGM needs a more precise charging profile to avoid losing life quickly — an EFB tolerates the classic alternator profile better. 💡 If in doubt, play it safe: buy a Start-Stop battery (EFB or AGM). It works in Start-Stop cars and non-Start-Stop cars alike, lasts longer and avoids any risk. You only pay a few euros more than a conventional one.

This vehicle uses a conventional flooded battery: no BMS registration is required, the alternator will charge it directly.
