Car battery by model
It depends on the generation and on whether your Seat Leon has Start-Stop.

The Seat Leon II 1P (2005-2013) almost always takes a battery like the Varta E11: conventional, 74 Ah and 680 A, case size L3. Below you will find all 4 generations, each with its battery.

## How the Seat Leon battery has changed

Start-Stop becomes widespread with the Seat Leon III 5F (2012), and with it come AGM and EFB batteries. Earlier generations —Seat Leon I 1M and Seat Leon II 1P— use conventional batteries from 52 to 74 Ah. The most common case size is L3, but not every generation uses it: check yours before you buy.

## How to tell which Seat Leon you have

Each generation has its own production years and model code, which you will find in the car’s documents. These are the body styles of each one:

| Generation | Years | Body styles (model code) |
|---|---|---|
| Seat Leon IV (KL) | from 2019 | Leon (KL1, KLG), Leon Sportstourer (KL8, KLD) |
| Seat Leon III (5F) | 2012-2020 | Leon (5F1), Leon ST (5F8), Leon SC (5F5) |
| Seat Leon II (1P) | 2005-2013 | Leon (1P1) |
| Seat Leon I (1M) | 1999-2006 | Leon (1M1) |

## Frequently asked questions

### Which battery does the Seat Leon take?

It depends on the generation and on whether your Seat Leon has Start-Stop. With Start-Stop, the Seat Leon III 5F (2012-2020) usually takes a battery like the Varta A7: AGM, 70 Ah and 760 A; without Start-Stop, the Varta D24 (conventional, 60 Ah). The Seat Leon II 1P (2005-2013) almost always takes a battery like the Varta E11: conventional, 74 Ah and 680 A, case size L3. Below you will find all 4 generations, each with its battery.

### Do all Seat Leon generations take the same battery?

No. The battery changes with the generation, the engine and Start-Stop: the Seat Leon III (5F) mostly takes the Varta A7 (AGM) and the Seat Leon II (1P) the Varta E11 (conventional).

### Since when has the Seat Leon had Start-Stop?

It became widespread with the Seat Leon III 5F (2012). Those versions need AGM and EFB; if your Seat Leon is older or has no Start-Stop, it takes a conventional battery.

### How do I know which generation my Seat Leon is?

By the years of manufacture (Seat Leon I (1M): 1999-2006; Seat Leon II (1P): 2005-2013; Seat Leon III (5F): 2012-2020; Seat Leon IV (KL): from 2019) or, more easily, with your number plate: our search identifies the exact model and engine and shows you only the batteries that fit.
