NMC fleet average at 100,000 mi

Based on real-world fleet data across Long Range and Performance Model Y vehicles.

World's best-selling EV

Largest fleet data sample

The Model Y's popularity means more real-world degradation data than any other Tesla — making benchmarks more reliable.

8 yr / 120k mi

Warranty period (all trims)

All Model Y variants: 8 years or 120,000 miles, minimum 70% capacity retention.

Model Y NMC variants (Long Range and Performance) show gradual, predictable degradation that settles into a long plateau after the first 25,000 miles. Owners in hotter climates or who rely heavily on Supercharging tend to see slightly faster degradation, but the overall fleet average remains healthy well into six-figure mileage.

NMC (Nickel Manganese Cobalt)

Trims: Long Range RWD, Long Range AWD, Performance

Long Range & Performance

Charging tip

Set your daily charge limit to 80–90%. The Long Range AWD holds capacity well — consistent charging habits matter more than peak mileage.

LFP (Lithium Iron Phosphate)

Trims: Model Y Standard (some markets), Model Y Juniper RWD (2025+)

Standard / RWD (select markets)

Charging tip

LFP cells tolerate 100% daily charging. A monthly full charge helps the battery management system maintain accuracy.

Cell chemistry determines how you should charge. LFP owners can charge to 100% daily; NMC owners should stay at 80–90% for daily use.

Cell format

Model Y: 2170 (most trims), 4680 (some variants from 2022+, Juniper 2025). Battery capacity ranges from 57.5–79 kWh depending on trim and model year.

Model Y battery health FAQs

How much does a Tesla Model Y battery degrade?
Aggregated owner data puts the nickel Model Y (Long Range and Performance) near 88% capacity at 100,000 miles. As the world's best-selling EV, the Model Y has a larger degradation sample than any other Tesla, so the benchmark is unusually reliable.
Which Model Y trims use an LFP battery?
Select Standard / RWD variants and the 2025 Juniper RWD use LFP; Long Range and Performance use nickel cells (NCA/NMC). Charge LFP to 100% daily, and keep nickel packs at 80–90% for everyday use.
What is the Model Y's battery capacity?
Usable capacity spans roughly 57.5 kWh on the Standard trim to 79 kWh on the 2025 Long Range AWD and Performance, with most Long Range cars around 75 kWh. See the table above for each variant.
What is the Model Y battery warranty?
Every Model Y trim is covered for 8 years or 120,000 miles, with a minimum 70% capacity retention guarantee.
