Well, do you easily find a refueling station in the middle of the forest? If you brought spare fuel containers, why wouldn't you bring all-the-same spare batteries?

Energy density is probably quite important for something handheld like a chainsaw. I doubt batteries are able to replace that except for some light garden use.

This. A 5l can of fuel is easier to drag along and I suspect current battery tech won't be good enough for professional use.

I have a chainsaw that runs on mains power. It's really nice (and quiet) for smaller tasks close to the house, but it doesn't help once you get outside extension cord-range.

40 volt electric chainsaws are fine for anything under 6 inches in diameter. That covers almost all household use cases as well as many trail thinning situations.

Yeah, the current offerings just won't cut it for professional use though, which I suspect account for much of chainsaw emissions.
