We made the switch to all battery yard equipment a couple of years ago (Ego brand). Mower, string trimmer, blower, edger, tiller head for the string trimmer. I've had to replace the string trimmer head (40 bucks) 'cause Mrs. P has a tendency to run it along the ground so the plastic wore down. Other than that, I'll never go back. The battery has enough juice to get through the entire sequence of mow, trim, edge, clean up with the blower...and then some.
If my Cub Cadet snow thrower ever dies, I'll get an Ego snow thrower too.
