- Carla, a Swedish used-EV retailer, analyzed 9,954 AVILOO battery diagnostics from 2022–2026 and found the Tesla Model 3 with CATL's LFP pack averaged 93.3% battery health past 62,000 miles — a five-point gap over the worst-performing Panasonic NCA version of the identical car.
- LFP chemistry tolerates 100% charges and high heat far better than nickel-based cells, which Tesla recommends limiting to 80–90% for daily use — a charging habit gap that compounds over tens of thousands of miles, per the source.
- Tesla originally moved Standard Range Model 3 and Model Y to LFP to cut cost and reduce nickel dependency; the new data suggests owners received a significant longevity benefit as a side effect.
- The Kia e-Niro and Hyundai Kona — mechanical twins on a shared 64 kWh pack — topped Carla's broader 20-model ranking at over 97% average battery health past 62,000 miles.
- Geotab, drawing on 22,700+ vehicles, found EV batteries now degrade about 1.8% per year, low enough that packs could last 20+ years and outlive the car around them.
- Tesla's own internal data shows Model 3 and Model Y Long Range packs lose roughly 15% capacity after 200,000 miles, with most degradation front-loaded before the curve flattens.
Why it matters: A used-EV buyer comparing two 2022 Model 3s at the same mileage and price could face a five-point battery-health gap with no way to tell from the window sticker which pack is inside — making third-party diagnostics like AVILOO's effectively mandatory before purchase, and reframing LFP from a 'budget' downgrade to the more durable option for long-term owners.
