How Battery Degradation Impacts Resale

Battery degradation in EVs in the U.S. affects resale—buyers worry about range loss and replacement cost. Here's how battery degradation impacts resale and what to expect when buying or selling a used EV.

TL;DR Battery degradation (range loss over time) can hurt used EV value—buyers discount the risk of lower range and future replacement cost. EVs with strong battery warranty and proven durability can hold value better. When buying or selling used EV, check remaining warranty and expected range. Use autopremo.com price checker and depreciation calculator.

How Battery Degradation Impacts Resale

• Range loss — batteries lose capacity over time (often 1–3%/year); after 5–8 years, range can be 10–20% lower. Buyers discount that—so resale can be lower than a gas car with similar age/miles.
• Replacement cost — out-of-warranty battery replacement can cost $5,000–$15,000+. Buyers factor that risk into what they'll pay.
• Warranty — remaining battery warranty (e.g., 8 years/100k miles) can support resale; buyers pay more for warranty remaining. When selling, highlight remaining warranty and current range.

What to Do When Buying Used EV

• Check remaining battery warranty — years and miles left. More warranty = less risk and often higher value.
• Check current range — if possible, see state of charge and estimated range (or get a battery health report if available). Factor degradation into what you'll pay. Use autopremo.com price checker to see comps for that model and year.
• Factor replacement cost — if warranty is short or gone, factor potential battery cost into total cost of ownership. Use autopremo.com total cost of ownership when planning long-term.

What to Do When Selling Used EV

• Highlight remaining warranty and current range (if you have data). Price to comps for same model, year, and similar mileage. Use autopremo.com price checker.
• Disclose known degradation — if range has dropped significantly, disclose it; price accordingly.
