Battery failure is unpredictable and the charge capacity can take an absolute nosedive over just a few months after years of being completely ok. There’s a reason there’s no standard model for battery wear
When we analyzed EV battery health in 2019, we found that EV batteries degraded, on average, at a rate of 2.3% per year. However, a new 2024 analysis reveals a significant improvement: EV batteries now degrade at an average of 1.8% per year. This improvement highlights ongoing advancements in battery technology and durability.
According to Geotab research, EV batteries could last 20 years or more if degradation continues at this improved rate. This is particularly encouraging for fleet operators under pressure to reduce CO2 emissions.
In all likelihood, the car will be replaced for other reasons before battery range drops too far.
Interesting, stark difference from lithium batteries then.
1.8% per year is still way too much over 10 years though, let alone 20. People only talk about EVs as new cars, but people forget most people can’t afford to buy brand new cars.

Nope not how it works at all. It drops off slowly:

Those are lithium batteries. This stuff isn’t degrading as fast in the real world as was initially found.
A 350 mile car would become a 280 mile car in 10 years. It’s sufficient for 95% of drivers.
