From Fleetworld. I could take the longevity if I had an EV.

Contrary to persistent concerns about battery ageing, the analysis of 24,000 state of health (SoH) certificates for electric vehicle batteries confirms a longevity far superior to market perceptions.

The research reveals that battery degradation is slow and progressive: following a slight initial decrease, batteries drop around 1% every 25,000km (c.15,500 miles).

At 70,000km (around 43,500 miles), the battery displays 93% remaining capacity on average.

And at 160,000km (c.100,000 miles) or after six years of use, SoH remains above 90%.
