Mine's a fancy-pants Stihl battery mower, but it works quite well and has been doing so without problem since I bought it ~4 years ago. The other battery stuff from the same brand (trimmer, chainsaw, kombi-tool) have the same story.
What matters is the amortized cost per year, I think - more expensive up front but cheaper in the long run.
For instance, the MS182 [0] is a $270, 2.2cu in saw with a 16" bar listed "For homeowners and light duty work".
Meanwhile, the MS201 [1] is $1100 for a 2.1cu in saw with a 16" bar listed as "The lightest professional gas chainsaw from STIHL Perfect for delimbing work in forestry".
Service interval on the 201 will be much longer, and it's expected to last longer but is priced accordingly. I ended up having to buy one of their homeowner grade saws 10 years ago when I was up in the mountains and my saw died, that was all that was available locally. I'm certainly not a professional, but at the time my primary heat source was wood and I had always used the stihl pro-grade saws. However, that cheap stihl was an absolute piece of junk, it was half wore out after cutting 2 cords of firewood that first time. Terrible ergonomics and poor power to boot, even after reserving the saw for light-duty work it only lasted 2 years and was miserable to start and run the entire time.
At least they explicitly say that they are for light duty though, a less honest company would market everything as pro-grade. But don't just buy the name, while they make good quality products they also sell cheap crap under the same name. It also isn't that clear in a retail store besides the price which ones are the homeowner grade saws.

My battery mower is quiet enough that I don't feel terribly rude mowing at twilight.
