I had always used 2 stroke chainsaws but kept an eye on the development of the battery saws. It was enlightening to purchase a Makita battery powered impact gun for lug nuts and big jobs around the place, since it was more powerful than my air tools and way more portable.
I had the chance during "snowmaggedon" the winter of 20-21 here in Texas where it got too cold for my 2 stroke saw to run well, and we needed more wood. Went down to Ace Hardware and picked up an EGO saw to go with my blower and proceeded to cut over a truckload of dry wood with ease. Not sure what was wrong with my Stihl, since it usually runs well and I was running good non-ethanol fuel, but it just didn't work.
Since that time, I've used the snot out of the EGO saw, since it is way lighter than my farm boss, quieter, easier to use, etc. Cleared a bunch of cedars behind the house and cut a bunch of firewood. It's amazing actually.
And if it quits working in a few years and I can't get a new battery for it, I'll either go back to using my 2 stroke or buy whatever new improved saw that has come out to replace it. The labor and hassle saved is already worth the price I paid, not to mention the fact that I was able to heat my home for several days when I really needed it. It works fantastic for me.
It is interesting how many different kinds of battery saws people have mentioned using, and almost all are happy with their choice. That would indicate battery power is a superior technology for at least one segment of the saw market.
