## Description

Compact L0 car batteries of 40–44 Ah: compare cranking current and terminal layout, then order online with the final price including VAT.

## The smallest European car battery case

The L0 case measures 175 × 175 × 190 mm and is the shortest format in the European L series. It is used in small petrol cars with modest electrical demand, so capacities stay between 40 and 44 Ah and cold cranking current between 320 and 420 A. This section lists 12 models, two from each of Varta, Exide, Tudor, Kronobat, Fulmen and Deta, all of them conventional flooded lead-acid.
- **44 Ah options:** Varta B36 (420 A), Exide EB440 and Tudor TB440 (400 A), Kronobat PB-44.0 (420 A).
- **40 Ah options:** Varta A16 (340 A), Exide EC400 and Tudor TC400 (320 A), Kronobat SD-40.0B (340 A).

Measure the space in your battery tray before ordering: if your current battery is 207 mm long, you need an L1 instead. You can also check the whole range of [car batteries](https://bateriasonline.es/en/car-batteries) or filter by capacity among the [40 to 45 Ah car batteries](https://bateriasonline.es/en/car-batteries-40ah-45ah).

## Frequently asked questions

### Can I fit a 44 Ah battery where a 40 Ah one was?

Yes, as long as the case and terminal layout are the same. A slightly higher capacity and cranking current do no harm to the alternator or the electrics.

### Is there an L0 battery for a car with stop-start?

Not in this size: every L0 model here is conventional flooded lead-acid. Stop-start cars need EFB or AGM, which start at the [L1 car battery](https://bateriasonline.es/en/l1-car-batteries) format.

### How do I find the right L0 battery for my car?

Search by number plate (Spain, Portugal and Italy) or by VIN, or compare the reference, Ah and CCA printed on your current battery.
