Or when Dyson screws their batteries in and makes them part of the handle on the older models, then offers batteries that sensibly slide in on newer models as an upgrade? Meanwhile, all my Milwaukee M18 batteries sit in a drawer in the garage while the stupid Dyson one that is a different voltage charges and only lasts about 7 minutes (not an exaggeration) due to age / high power draw. You can get adapters for M18 batteries that work on Dyson V8 models, but not the newer stuff that has >18v batteries. enter ebikes, stage right I really dislike owning a dozen products that have the same damn rechargable lithium cells inside that I cannot move batteries between in any realistic or practical fashion. Even laptops and Teslas used to use 18650s! It's infuriating that there is zero incentive for companies to develop any kind of modular interoperable rechargeable battery under our current economic system, leaving us with only the trite solution of "just don't buy any modern electronic device, then".
