Swappable batteries resolve this issue pretty well. The energy density is far from comparable, but if you're already hauling a van or trailer to the job site, then a dozen spare batteries isn't an issue.
Except being very expensive, wear out after a few years (at best), and being sensitive to being in the hot sun all day every day. All in a profession mostly worked by under privileged people where frugality is a necessity of life.
Most batteries have 5 year warranties.
I can run a decent small engine for a decade and when it finally breaks I can rebuild it for $50 and get another decade out of it.
I have battery powered stuff for my home but for commercial use, literally thousands of work-hours, the battery tech isn't there yet.
