Is there a good set of things to check when buying a used electric car?

There are what look like good deals on lease return Leafs and Fiat e500s. Range isn't a concern since it would just be for local errands. I just want to know what to watch out for.
Update: Some of these electrics and hybrids look interesting : https://www.autoblog.com/photos/best-used-hybrids-ev-electric/#slide-7443479
