Chemistry

LFP

Warranty

8 years / 100,000 mi

Expected Degradation Rates

Like all lithium-ion batteries, your Model 3's battery will experience some capacity loss over time. Here's what to expect:

Year 1
3-5% capacity loss

Tesla batteries typically lose 3-5% capacity in the first year as they settle in. This initial break-in period is normal and expected for lithium-ion batteries.

Years 2+
~1% per 10,000 miles

After the initial break-in period, degradation slows significantly. Most owners see only about 1% loss per 10,000 miles with normal use.

200k miles
~85% capacity retained

Tesla's 2023 Impact Report shows Model 3/Y retain about 85% capacity at 200,000 miles. Real-world data from high-mileage Teslas consistently confirms excellent long-term retention.

Battery Chemistry: LFP (Standard Range)

Standard Range and base Model 3 use 54-60 kWh Lithium Iron Phosphate (LFP) cells, which handle 100% charging better. Long Range and Performance variants use 75-82 kWh Nickel Cobalt Aluminum (NCA) cells for higher energy density.

LFP Charging Tip

LFP batteries can be charged to 100% without the same degradation concerns as NCA batteries. Tesla recommends charging LFP batteries to 100% at least once per week to help the battery management system calibrate accurately.

Battery Warranty Coverage

Tesla's Model 3 battery is covered by a comprehensive warranty:

Duration 8 years
Mileage 100,000 miles
Retention Guarantee 70% minimum capacity

The warranty covers whichever comes first: 8 years or 100,000 miles. Tesla guarantees the battery will retain at least 70% of its original capacity during this period. If your battery degrades below 70%, Tesla will repair or replace it at no cost.

Additional Notes

Model 3 has one of the best-documented degradation curves thanks to its popularity. Tesla's 2023 Impact Report shows Model 3/Y retain about 85% capacity at 200,000 miles. LFP variants may show slightly different degradation patterns but generally perform similarly long-term.
