This is maybe getting tangential but one of my pet peeves is that the industry doesn't establish standards for large batteries, like lawnmowers and leafblowers.

This is maybe getting tangential but one of my pet peeves is that the industry doesn't establish standards for large batteries, like lawnmowers and leafblowers. If they were serious about electric transition they would make batteries transferable like AA, AAA batteries etc. I understand the issues involved and that there are nontrivial obstacles (see: IoT), but it is really frustrating to deal with manufacturer lock-in. I also think it adds to confusion of the sort in the linked piece because there isn't a discussion of standards per se along the lines you're mentioning. I suppose safety issues are magnified a hundredfold compared to the problems that people have run into with USB product standard mismatch but that's probably another reason why people might actually buy brand-name OEM batteries even if there were standards. I guess in general I wish there was some open industry discussion of this, even if it meant a white paper where they throw up their hands and decide it's too risky.
