What battery fits the Audi 100 C4 Saloon 2.3 E?

Audi 100 C4 Saloon 2.3 E (133 hp, petrol, 1990-1994) takes a conventional 74 Ah, 680 A battery (278 × 175 × 190 mm), with the positive terminal on the right. Compatible batteries offer 70-77 Ah, 680-780 A (CCA), 12 V, case H6/L3, conventional flooded technology. Browse the compatible battery list below.

Does the Audi 100 C4 Saloon 2.3 E need an AGM or EFB battery?

If your Audi 100 C4 Saloon 2.3 E has start-stop, regenerative braking or many electrical accessories, you will need an AGM or EFB battery. Check your vehicle's technical specifications.

What type of battery does my car need?

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.

What is the difference between AGM, EFB and standard batteries?

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.

Based on the batteries we found for your vehicle, our experts help you pick the right one.

📋 What we found

For your Audi 100 C4 Saloon 2.3 E we found 6 compatible batteries. This list includes 3 Start-Stop batteries and 3 conventional batteries (non Start-Stop).

⚡ Battery type for your vehicle

✓ Your Audi 100 C4 Saloon 2.3 E 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.

Before you buy: check 3 key points

Although the batteries shown are sourced from information provided by manufacturers, we recommend checking on your current battery:

Dimensions (length × width × height, including terminals and protrusions)
The dimensions shown are the maximum of the battery and include the height of the terminals, small ridges at the base and any lateral protrusions. Measure your current battery completely, from edge to edge. The new one must be the same size or slightly smaller — never larger, it would not fit in the housing.
Positive terminal (left or right viewed from the front — check the battery photo carefully)
Stand facing the battery, with the manufacturer's label facing you and the terminals on top. Locate the terminal marked with +: if it is on your right, it is "positive right"; if it is on your left, it is "positive left". Do not rely on how the battery is mounted in the car — the position is always measured looking only at the battery itself.
Technology (AGM, EFB or conventional — the same as your current battery or higher)
Depending on the manufacturer, the same technology may be labelled differently: AGM may also appear as VRLA, AGM Start-Stop or AGM Deep Cycle. EFB may appear as EF, EFB+ or Enhanced Flooded Battery. Conventional may appear as SLI, Lead-Acid, Wet or Standard. If your vehicle has Start-Stop, the battery must be AGM or EFB — never conventional.

If you have any questions, just ask us and we'll be glad to advise you with no obligation.
