How battery figures are labeled

Every EV listing shows a battery figure, labeled so you can tell them apart:

• Tested is a battery capacity test on file for that exact VIN. 0 of the 1 EVs shown here have one.
• Estimated from displayed range (shown as “Displayed range”) compares the range that exact car shows at a full charge with its original EPA rating. It is a calculation for that VIN, not a lab test. 0 of 1.
• Typical estimate (shown as “Est. ~X%”) is the typical figure for a car of that model, age and mileage from published fleet data (TeslaTracker for Teslas, sharpened with its per-trim figures; Geotab for other EVs). It is not a measurement of the car itself, and you can request a report. 1 of 1.
• Similar Teslas display is the full-charge range comparable used Teslas show (same trim, year and mileage), from TeslaTracker, with how many cars it is based on. It describes similar cars, not that one. 0 of 1.

Questions shoppers ask

How do I check a used Tesla's battery health?

A battery capacity test is the only measurement of the battery itself. Without one, compare the range the car displays at a full charge with its original EPA rating. Each EV page shows a test result, the displayed range we recorded, or a labeled estimate for its age and mileage, and you can request a report for the exact VIN. Neither a displayed range nor an estimate is a battery test.

Does a used Tesla still have warranty?

Tesla's battery and drive unit warranty is 8 years with a mileage limit of 100,000 to 150,000 miles depending on model and year, and it transfers to the next owner. We'll confirm the remaining coverage for any specific VIN.

Is a used EV eligible for a federal tax credit?

The federal used clean vehicle tax credit ended for vehicles acquired after September 30, 2025. Some utilities and California programs still offer EV rebates, so ask our finance team what applies on the date you buy.
