A documented Model Y Long Range test reference
ADAC’s March 2023 report covers a Maximum Range AWD (Long Range AWD) test car first registered in September 2022, on 20-inch wheels. Its specification lists 79 kWh net; ADAC reports 415 km in its Ecotest and about 33 minutes for 10–80% DC charging under favourable conditions. The capacity is a specification stated in that report, not an EVVerity measurement or a verified factory preset for every Model Y.
| Item | Reference | Buying implication |
|---|---|---|
| Net capacity stated in report | 79 kWh | Confirm the installed pack before using a capacity baseline. |
| Ecotest range | 415 km | An 80–10% window scales to roughly 291 km on the same test basis. |
| DC 10–80% time | About 33 minutes | Compare the full session window, not a peak-power photograph. |
Home charging: UK electrical-supply reference
Tesla’s UK support table lists 7.4 kW on a 230 V single-phase supply and 11 kW on a 400 V three-phase supply for Model 3 and Model Y. These are the current UK references, checked 4 October 2026; match an older or imported car to its own specification. A 22 kW wallbox does not make an 11 kW on-board charger accept 22 kW.
Battery warranty: separate US contract reference
Tesla’s current US table lists eight years / 100,000 miles for Model Y Rear-Wheel Drive and All-Wheel Drive, and eight years / 120,000 miles for its listed Premium and Performance versions. Both require at least 70% capacity retention during the warranty period; the earlier time or mileage limit applies. Check an older car’s original terms. This US warranty example and the UK AC table above describe different markets; they are not one combined specification for a single vehicle.
A battery-contactor recall to check on newer cars
Tesla’s US notice covers certain 2026 Model Ys built 15 March–15 August 2025 with affected battery contactors. A connection defect can cause loss of propulsion. Tesla replaces the affected contactors without charge. Check current VIN status with Tesla; this specific campaign does not describe every model year or replace a complete recall check.
Check the journey that makes the car useful to you
Write down your longest regular journey, the charge available before departure and a reserve for an alternative charger. The worked 291 km window above is an illustration for ADAC’s tested car and cycle. It is not a promise for a different pack, cold weather, a trailer or roof equipment.
Ask for a dated battery-health record and a charging-session record before travelling. Keep the state-of-health result separate from the test report’s original capacity: one describes the seller’s car, while the other provides comparison context.

Battery options & usable capacity
A Long Range, Rear-Wheel Drive or Performance badge alone does not provide a verified usable-capacity baseline. EVVerity does not convert a battery marketing label into a capacity measurement.
Charging capability
Check local connector compatibility, home AC limits and a documented DC charging session. Record the battery’s starting charge and temperature alongside charging power.
A Battery Health screen and a Battery Health Test are different evidence
Tesla’s current Model Y manual distinguishes a battery-management estimate on the Battery Health screen from an optional Battery Health Test. Availability depends on the vehicle. The manual says the test can take up to 24 hours and recommends it only when there is concern about energy retention. It is not a quick check to improvise during a viewing.
Ask the seller which result they are showing, when it was obtained and whether the feature is supported on this car. If further testing is appropriate, let the owner follow the applicable manual or arrange qualified service. Keep the original report or screen record with the vehicle’s pack and repair history.
| Evidence | What to record | What it cannot establish alone |
|---|---|---|
| Battery Health screen or completed test | Date, method, feature name and matching vehicle | The status of every battery component or a guaranteed warranty claim. |
| Displayed range at a charge percentage | Charge level and the display’s basis | A laboratory measurement of usable capacity. |
| Recent trip consumption | Distance, speed, weather, tyres and heating use | Performance in a different season or journey. |
Arrange the evidence before travelling to view the car
Send the seller a short request for the available battery evidence, original market, variant, service history and charging demonstration. If a report is missing, record it as missing. Do not fill the gap with a universal Model Y battery capacity or infer a defect merely because a particular software feature is unavailable.

Plan a journey with this battery reference
This guide has no verified original usable-capacity preset. Use a matching documented value, or label your own estimate clearly, before calculating range.

Battery warranty
Use the warranty issued for this vehicle. Current Tesla warranty pages distinguish variants and markets; a used-car advert is not proof of remaining battery coverage.
Things worth checking before purchase
- Request the vehicle’s Battery Health screen or report if supported by its software and equipment.
- Ask whether towing, roof accessories or wheel changes were present during the range and consumption sample.
- Confirm pack replacement history and whether the reported SoH relates to the installed pack.
- Obtain the warranty start date and mileage limit directly from the supporting documents.
A Model Y viewing: match the evidence to the car
Ask for the exact version, original sales market and any battery replacement paperwork. Keep the specification reference, diagnostic report and the seller’s range screenshot as separate records. A Model 3 procedure or capacity figure should not be assumed to apply to a Model Y.
Check the actual charging arrangement you plan to use: vehicle connector, included cables and compatible home supply. During an agreed charging demonstration, record the starting charge and conditions alongside the observed power. A single momentary reading cannot establish the full charging curve.
Use recent consumption for your own city or motorway scenario. If the seller only has a dashboard range number, request supporting evidence before estimating usable capacity.
How to assess remaining usefulness, not a fixed battery lifespan
Ask for the installed battery’s history and recent evidence, then calculate a realistic journey with a reserve. Age, mileage and a warranty date cannot establish a fixed replacement date. A Model 3 health-test procedure should not be assumed to be available on a Model Y; follow the documentation for the actual vehicle.
Turn the evidence into a useful estimate
Use a documented usable capacity and consumption from conditions matching your trip. Keep original specifications separate from the seller’s current battery-health evidence.
