Tesla Model Y RWD Battery Degradation

Estimated realistic range of the Tesla Model Y RWD over ten years at typical UK mileage, against the usual 70% capacity warranty floor.

About these figures

Current UK base (CATL LFP pack). Earlier 2022-24 RWD cars used a 60.0kWh pack with 11kW AC and 311 miles WLTP.

What degradation looks like on a Tesla Model Y RWD

From a realistic 267 miles when new, a typical Tesla Model Y RWD still manages about 241 miles at 5 years (90% health), 227 miles at 8 years (85%) and 217 miles at 10 years (81%).

The first year usually shows the biggest single drop as the pack settles, after which the fade slows to a crawl. Batteries almost never fail outright; they just gradually carry a little less.

Most manufacturers warrant the battery for 8 years or 100,000 miles against falling below about 70% capacity. On this car, 70% health still means around 187 miles of realistic range.

Habits that keep the battery healthy

Charge to 80% for daily use and save 100% for long trips
Avoid leaving the car parked for weeks at 100% or near empty
Use AC charging for routine and rapid charging for journeys
Do not fear normal use: the management system protects the pack far better than folklore suggests

FAQs

How long does the Tesla Model Y RWD battery last?

Comfortably beyond the 8 year, 100,000 mile warranty for a typical car. At ten years, expect around 81% capacity, which still means about 217 miles of realistic range.

How much range does a 5 year old Tesla Model Y RWD have?

A typical example retains about 90% battery health, which translates to roughly 241 miles of realistic range against 267 when new.

Is the Tesla Model Y RWD battery covered by warranty?

Manufacturer battery warranties typically run 8 years or 100,000 miles and protect against capacity dropping below about 70%. Check the exact terms for the year and market of the specific car.

Should I get a battery health check before buying?

Yes. Individual cars vary with climate and charging habits, and a specialist can measure the true state of health in under an hour. For a used Tesla Model Y RWD, that number is worth more than any average.
