I used to think battery life span would be the achillies heel of electric vehicles, I think because the earliest models were overly cautious and had you lease the battery as an option with some talk of 7-year life spans. No doubt the right-wing newspapers and shows like Top Gear trumpeted this at the time.
Fortunately, battery technology has come a long way, and is massively outperforming some early expectations.
Tesla on the road have batteries that are on course to last 300,000 to 500,000 miles before they need replacing.

It's hard to find figures for refuse lorries mpg but here's an article:

Also, my £65k estimate for a new lorry was probably way off, I noticed after posting that figure was on a basic model from 2006. The modern sort a council probably needs with seperation is more likely to be triple that from another article I saw.
