The Fiat 500e battery: what it is worth, year by year
Fiat 500e, since 2020, pack of about 42 kWh. Versions and capacities, manufacturer warranty, expected state of health, possible battery lease and the cost of a failure.
Indicative estimate, excluding diagnosis.

Remaining warranty, expected state of health, battery lease and cost of a failure. All at once — and nothing you enter leaves your browser.
We check, we don’t certify. The date of first registration is shown in box B of the V5C logbook. The state of health given is a range calculated from the battery’s age, mileage and chemistry: only a measurement on the vehicle gives a figure.
Battery versions of the Fiat 500e
A model sold over several years does not have the same battery from start to finish, and two versions are often sold side by side. Identify yours: capacity and chemistry change the range, the expected degradation and the cost of a replacement.

The expected state of health of a Fiat 500e battery
Three model years of this car, at the average French annual mileage of 9,321 miles, each with its chemistry. These ranges describe where a comparable battery usually sits, not yours: use, climate and charging habits spread the fleet widely.
- 2020 model year81 to 90%6 years, 55,923 miles, chemistry not recorded
- 2023 model year88 to 95%3 years, 27,962 miles, chemistry not recorded
- 2026 model year98 to 100%under a year, chemistry not recorded
For a figure rather than a range, you need a measurement on the car. What state of health means and how it is measured.
What the energy costs per 100 miles
Charged at home, a Fiat 500e uses between £5.51 and £7.89 of electricity per 100 miles.
By comparison, a recent petrol car averages 38.7 mpg (7.3 L/100 km) in real-world use: about £20.30 of fuel per 100 miles, at the average price of unleaded petrol (£1.728 per litre on 2 November 2026).
Bottom of the range: the WLTP official consumption, from 4.2 to 4.8 miles/kWh depending on the version. Top: 25% more, the measured gap between official figures and real-world use. Electricity at £0.2632 per kWh, the Ofgem price cap.
Charging at a public charge point: prices vary too much from one operator to another to be given here.
Compare the cost of every modelSources: consumption from the manufacturer or the European registration database; electricity: Ofgem Energy Price Cap, 1 October to 31 December 2026, direct debit, Great Britain average, no VAT (announced 26 August 2026); real-world gap: TNO 2025 and ICCT 2025; petrol: JRC 2025 and weekly road fuel prices from the Department for Energy Security and Net Zero (DESNZ). Checked on 21 September 2026.
Charging at home: a night on a plug
Plugged in for 8 hours on a 3-pin plug, a Fiat 500e adds between 60 and 90 miles; on a 16 A commando socket, between 100 and 140 miles, depending on the version and how it is driven.

The Fiat 500e battery
Sold since 2020, with a pack of about 42 kWh.
The Fiat 500e pack can be repaired module by module. When only one module is at fault, the repair costs far less than a new pack.
Which battery does the electric Fiat 500 have?
The electric Fiat 500, or 500e, on sale since 2020, comes with two batteries: 23.8 kWh on the entry-level Action and 42 kWh on the others. Both packs have been built side by side since launch: the model year will not tell them apart, so check the version on the advert or the invoice.
The battery was never offered on lease: it always belongs to the car. The pack can be repaired module by module, which limits the cost of a fault out of warranty.
How long does the electric Fiat 500 battery last?
Nobody publishes a lifespan in years for these packs, and that is not the right question anyway. A battery wears with the number of cycles, with heat and with rapid charging. With an official efficiency of 4.2 to 4.8 miles/kWh, a 42 kWh 500e completes a full cycle every 175 to 200 miles, a 23.8 kWh one every 100 to 115 miles: at 6,000 miles a year, that is around thirty full cycles for the first and around sixty for the second. For the same mileage, the small battery works twice as hard.
What matters for a used 500e is the measured state of health: the section above gives the expected range by year. Before you buy, ask for a battery health check.
The 500e battery warranty
Fiat’s warranty booklet in Italy covers the 42 kWh battery for 8 years or 160,000 km (about 100,000 miles), whichever comes first, with a replacement if capacity drops below 70%, provided the scheduled servicing has been done: keep the invoices. The 23.8 kWh battery is not in it, and sources disagree on its cover (100,000 km, about 62,000 miles, over 5 or 8 years). Terms vary from country to country: the ones for yours are shown on this page.
