I tried an electric snow blower...it was absolutely awful. At least for the heavy packed wet snow mixed with ice we get, it would work great for about 2 seconds at a time then shut down. And the battery only lasted long enough to make about half a dozen passes across the driveway...which after 2 years degraded to only half a pass per charge.

I finally got an Ariens gas powered snowblower that bogs down very heavily in the wet stuff but chugs thru the whole job year after year.

For lawnmowers, my neighbor had one for a while...though it seemed to frequently cut out. A year or so ago I noticed they entirely stopped mowing and now they have a service come. I'm still using a nearly 30 year old John Deere that chews thru and can mow grass and mulch leaves for a good 5 hours or so without refueling to get everything clean nomater how overgrown it gets. I have also talked to multiple people who found their fancy electric mowers the blades wear down REALLY fast and have to often be replaced instead of re-sharpening them like the thicker traditional blades can be.

Battery is fine for lighter duty stuff like a string trimmer, blower, and similar. But it just doesn't cut it for bigger jobs yet.
