I wonder how long these new electric mowers will last? When a Chinese motor controller fails on your E-lawnmower will a replacement be available? I doubt it. Not to mention, electronics combined with heat and vibration tend to fair poorly, and there not making these lawnmowers to the same quality standards of a car ECU at this price point, more like a cheap toaster.
You can bet there is planned obsolescence engineered right into every part of these machines. Maybe Milwaukee brand equipment will last longer but I would definitely buy the longest available extended warranty on electric mowers.
You'll know when the stores admit that these products are e-waste is when they stop selling the extended warranties. This happened to me on a halogen work light (they are flicker free when filming as compared to LED despite 60hz frame correction). Lowes and HD don't offer extended warranties on these because they are poorly built and appear have high return rates according to the reviews, the store won't take that gamble though the manufacturer most likely would refund you after the warranty period if you ask (as they have for me).
Then real battle that the save-the-planet crowd should be fighting for is against crappy products instantly turning into e-waste. With poor engineering and lack of available parts (i.e. Samsung appliances) a usable product ends up in a landfill. How's that good for the planet? No need to recycle if the machine doesn't degrade into garbage after 2 years.
How many of those late fall electric mower returns are actually getting resold or going to auctions? I bet a good amount gets trashed. All that energy, materials, and mining for a battery, controllers, deck, and motor magnets right into a dumpster.
The Macbook is a good example of e-waste ebcause you can't change the SSD. The SSD is part of the motherboard and not replaceable, the only way to change it is a with new motherboard which costs almost as much as a new MBP. Out of warranty this is instant e-waste.
If you are skilled and crazy enough to de-solder and re-ball the SSD, it might not even work because it is probably serialized, requiring proprietary software to initialize. Some of the newer MBP models have issues where a short in the power supply controls NEXT to the SSD fails and reverse feeds power right into the SSD, frying your memory.
