Battery Degradation: How Much Range You Really Lose
EV batteries do fade, but slower than most buyers fear. Real-world data shows about 1–2% capacity loss per year, and that gradual slide matters far more for resale than for daily range.

Key takeaways
- Expect roughly 1–2% capacity loss per year of typical use.
- Heat and frequent DC fast charging speed degradation.
- A 64 kWh pack at 85% health still covers most daily driving.
- Battery state of health is now a core resale factor.
The actual fade rate
Long-term fleet data puts most modern EVs at about 1–2% capacity loss per year. A car that showed 250 miles of range new might show 215–225 after eight years. That is a real drop, but it rarely strands anyone — daily driving is far below max range.
What wearing down really feels like
| Year | Est. state of health | Usable range (250 mi new) |
|---|---|---|
| 1 | 99% | 248 mi |
| 4 | 93% | 233 mi |
| 8 | 86% | 215 mi |
The habits that age a pack faster
Keep charge between 20% and 80% for daily use, avoid leaving it at 100% or 0% for weeks, and limit DC fast charging in summer heat. None of this is magic, but it measurably slows the slide.
Why resale cares more than you do
A buyer cannot see degradation, so they assume the worst. Two identical cars — one at 90% health, one at 80% — can sell $1,500–$3,000 apart even when both cover the same commute. Battery health reports are becoming as normal as a Carfax. See our <a href="/guides/used-ev-buying-battery-inspection-guide">used-EV battery inspection guide</a> before buying used.

A used EV lives or dies by its battery. Pull a health report, check charge habits, and watch for cold or crash damage before you sign — the pack is the whole deal.
EV Depreciation Is Finally Calming Down
Early EVs lost value fast — tech moved quickly and the federal credit hid true cost. With the credit gone and the market mature, depreciation is converging toward gas-car norms, though battery fear still weighs on price.
What Happens to an EV Battery at the End
Very few EV batteries are truly "dead." Most retire from cars with 70–80% capacity and move to storage or get recycled for their metals. The "landfill" fear is mostly myth.
