The Tesla Model Y battery: what it is worth, year by year
Tesla Model Y, since 2020, pack of about 75 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 Tesla Model Y
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 range estimate drifts until the car has recently been charged to 100%: until then, the displayed range says nothing about battery health.
- Charging noticeably slower in cold weather than on the nickel versions.

The expected state of health of a Tesla Model Y 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.
- 2021 model year83 to 92%5 years, 46,603 miles, NMC chemistry
- 2023 model year88 to 97%3 years, 27,962 miles, LFP or NMC depending on the version
- 2024 model year91 to 99%2 years, 18,641 miles, LFP or NMC depending on the version
For model years where two chemistries appear, the range covers both: LFP holds up better over time than nickel, and the gap widens with age. The battery checker will ask for your version to give an estimate that covers yours alone.
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 Tesla Model Y uses between £6.65 and £9.16 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 £19.75 of fuel per 100 miles, at the average price of unleaded petrol (£1.681 per litre on 14 September 2026).
Bottom of the range: the WLTP official consumption, from 3.6 to 4.0 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).

Specifications and price ranges given as an order of magnitude, still being confirmed with garages. Only a price given after diagnosis is binding.
The Tesla Model Y battery
Sold since 2020, with a pack of about 75 kWh.
The Tesla Model Y pack does not lend itself to module-by-module repair. A diagnosis is still worthwhile: the fault often lies in an ancillary component rather than the pack itself.
Faults reported by garages in France
- Bonded structural pack: repair limited to full replacement.
- Diagnosis often points to an ancillary component rather than the pack.
