Model 3 capacity and range: two independently tested versions
Green NCAP measured usable battery energy in the two rear-wheel-drive cars below. These are results for the tested vehicles, not universal factory specifications or measurements of a car offered for sale.
| Tested version | Measured usable energy | Range in the cited tests |
|---|---|---|
| 2022 Standard Range Plus, RWD | 61 kWh | About 450 km in standard real-world conditions with moderate climate-control demand. |
| 2024 Rear-Wheel Drive | 60 kWh | 475 km on the mixed on-road drive at 20°C on a dry, sunny day; 324 km in the BAB130 highway test. |
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 3 Rear-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 2025 Model 3s built 8 March–12 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.
What the test results mean for a used-car shortlist
Using the 2024 test ranges only as an illustration, an 80% to 10% charge window represents about 333 km of that mixed route, or 227 km of that highway cycle. This is 70% of each full-range result, not a separate road test. A 250 km motorway journey therefore needs a different charging plan from a 250 km mixed trip, even before allowing for age, cold weather or diversions.
For an actual purchase, compare the seller’s dated battery report and a journey resembling yours. A Long Range or Performance car needs a different reference; the two RWD test results above are not suitable denominators for its degradation calculation.

Battery options & usable capacity
The independent RWD tests above measured 61 and 60 kWh in their respective vehicles. For a degradation calculation, match the installed pack and software to an original usable-capacity baseline; a test of another car is comparison context.
Charging capability
Confirm the AC limit and DC specification in the manual for the car’s market and build period. A charger’s advertised power is not a promise that the vehicle will sustain that rate.
Three different warranty questions for a used Model 3
A seller saying “still under Tesla warranty” leaves three questions unanswered: which cover remains, when it ends and whether it applies to this transaction. Tesla’s current US support page separates the basic vehicle warranty, the battery and drive unit warranty, and additional cover for qualifying cars purchased directly from Tesla. Tesla says the warranty supplied with the car is authoritative; a current webpage is not a replacement for it.
| Seller’s claim | Evidence to ask for | What it does not establish |
|---|---|---|
| “The car is under warranty” | The original market, in-service date, mileage and the applicable warranty document. Ask the owner to show Specs & Warranty → Warranty in the Tesla app. | That every component or type of damage is covered. |
| “The battery warranty lasts eight years” | The exact variant and both the time and mileage limits in its own terms. | A fresh eight-year period from your used purchase date. |
| “It has Tesla used-car cover” | Proof of the eligible direct-from-Tesla purchase and its cover dates. | That the same additional cover accompanies every third-party sale. |
A range claim needs a consumption figure
Consider a seller’s illustrative claim of 250 miles at a full charge. At an assumed 250 Wh/mile that implies 62.5 kWh; at 300 Wh/mile it implies 75 kWh. The 12.5 kWh difference comes entirely from the consumption assumption, not a change in the car. Neither result verifies this Model 3’s capacity or state of health.
At a viewing, keep a dashboard range prediction, trip consumption and any diagnostic result as separate records. Ask when and how each was obtained. If a diagnostic percentage is supplied, ask for the report date, method and matching original usable-capacity reference. An unidentified “Long Range battery size” from an advert is not a sound denominator.

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
Tesla’s current US warranty lists different mileage limits by variant and a capacity-retention condition. Do not apply today’s table automatically to an older car; obtain its original warranty terms and start date.
Things worth checking before purchase
- Ask for a dated Battery Health result where the feature is available; Tesla notes that not all vehicles have it.
- Check whether the installed pack is original or a documented replacement, and use the correct capacity baseline.
- Compare the charge-port connector, available adapters and local network compatibility for imported vehicles.
- Record tyre size, temperature and recent consumption before interpreting the displayed range.
Checking battery health on a used Model 3
Tesla’s current Model 3 owner’s manual describes Battery Health under Controls → Service. Availability depends on the vehicle. The displayed evaluation and the optional Battery Health Test should be distinguished from the everyday range display. Ask the seller which screen their screenshot shows.
The optional test may take up to 24 hours and has specific charging, connectivity and starting-charge requirements. Follow the manual for the actual vehicle rather than trying to reproduce the process during a short viewing. Tesla advises using the test when there is concern about energy retention.
If Battery Health or its optional test is unavailable, consult the manual for that exact vehicle and ask Tesla about supported features. An absent menu is not itself evidence of poor battery condition. EVVerity cannot enable the test.
For your viewing notes, retain the result date, odometer, exact variant and method. Request repair documentation if the installed pack has changed. An advertised trim name is not enough to choose an original usable-capacity denominator. If that baseline cannot be established, keep the capacity comparison blank and discuss the available diagnostic evidence instead.
Tesla battery life and warranty: two different questions
A battery-health assessment describes energy retention at a particular time. It does not predict how many years a used Model 3 has left. Keep any warranty end date separate from present condition and future repair expectations. Check the original contract, actual start date, distance and exact version with the warrantor; current terms for a new vehicle may differ.
For a cost comparison, separate a battery-test fee, an actual repair quote and electricity bought for charging. None can be inferred from an odometer reading or a full-charge range screenshot alone.

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.
