Fiat 500 — two different cars. The 500 Hybrid (series 312) takes a 207 × 175 × 190 mm battery (UK 012 case), EFB or AGM, 50–55 Ah, 530–540 A EN. For the 500e (series 332) 12V auxiliary battery we have no verified data and will not publish a figure. Search on Amazon
Fitment varies by engine and build date — the full breakdown and our sourcing notes are below.
Battery Specifications
| Car | Battery | Technology | Capacity & CCA | Case |
|---|---|---|---|---|
| Fiat 500 Hybrid (series 312) — 1.0 FireFly mild hybrid petrol | UK 012 case | EFB or AGM. The car has stop/start and a belt starter-generator, and every listed product is a start-stop unit flagged for brake energy recovery. | 50 / 54 / 55 Ah; 530–540 A (EN), individual products to about 560 A | 207 × 175 × 190 mm, B13 hold-down, T1 terminals |
| Fiat 500e (series 332) — battery electric | No data available | No data available | No data available | No data available |
- Correction. This page previously published a single answer — type 063, standard flooded, 40 Ah, 340 CCA in a 207 × 175 × 175 case, with “start-stop not required”. That is wrong for the 500 Hybrid on every field, and a plain flooded battery should not be fitted to a stop-start car with a belt starter-generator.
- We are not publishing a figure for the 500e. Fiat’s own handbook gives no Ah or CCA for the 12V auxiliary battery, and the catalogue returns an unusably broad set spanning three case lengths, 42–65 Ah and 390–640 A. That is a compatibility superset, not a specification. Check the label on the battery in the car.
On the 012 type code. The 207 × 175 × 190 mm footprint is the UK 012 case, but we established that by dimensional match rather than from a UK retailer listing 012 against this car by name. Treat the code as indicative and the dimensions as the reliable figure.
Confidence in this data: Medium for the 500 Hybrid — dimensions, capacity and cranking figures come from the catalogue at engine-code level, but Fiat publishes no Ah or CCA of its own and we found no Fiat statement mandating EFB or AGM. No data available for the 500e.
Checked against the TecDoc-derived application data at engine-code level, cross-referenced with Bosch, Varta, Exide and Yuasa product listings. Where the catalogues disagree, or list nothing, this page says so.

Frequently Asked Questions
What battery does a Fiat 500 need?
It depends which Fiat 500 you have. The 500 Hybrid (series 312, the 1.0 mild-hybrid petrol) takes a 207 x 175 x 190 mm battery — the UK 012 case — of 50 to 55 Ah and 530 to 540 amps EN, as an EFB or an AGM. For the electric 500e (series 332) we have no verified specification for the 12V auxiliary battery and will not publish one.
Is the Fiat 500 electric?
Only one of them is. Fiat sells the electric 500e (series 332) and the petrol 500 Hybrid (series 312) side by side in the UK, and has done throughout this period. They are separate vehicles in the parts catalogues and share very few service parts. An earlier version of this page said the Fiat 500 is a fully electric vehicle, which was wrong.
Does the Fiat 500 Hybrid need an EFB or AGM battery?
In practice yes. The car has stop/start and a belt starter-generator, and every battery the catalogue lists against it is an EFB or AGM flagged for stop-start and brake energy recovery. We could not find a statement from Fiat mandating it, so we will not attribute the requirement to Fiat — but do not fit a plain flooded battery.
Will a 063 battery fit a Fiat 500 Hybrid?
No. A 063 is 207 x 175 x 175 mm and this car takes a 207 x 175 x 190 mm case, so the 063 is 15 mm too short to clamp correctly. It is also the wrong technology for a stop-start car.
Can I change a Fiat 500 battery myself?
Usually yes, but a stop-start car often needs the new battery registered to the vehicle so the charging system treats it as new. Check whether yours requires that before you buy, and factor in a garage visit or a suitable diagnostic tool if it does.

How we check fitment for this guide
We cross-reference fitment figures against manufacturer specifications and OE-supplier catalogue data where available, and matched to the standard codes that actually govern fit — battery type/group sizes, wiper lengths and fitting types, bulb fitment codes, tyre size markings, and oil specifications. We work by make, model, year, engine, and build date, because a single model can take different parts across its life. Where the right part depends on your exact vehicle, we tell you to confirm by registration or VIN. More on our method →
