It’s a similar problem to lead acid batteries. 2V cells are arranged in a way that will deliver 12V at sufficient current for a particular application. However the solution we have landed on is completely different to li-ion because you can take any suitably sized car battery from one brand of vehicle and put it in another. The reason for that is the interface is common to virtually all cars. This technology pre-dates enshitification. There is no good reason to tie any battery to any device other than it helps the shareholders. They are busy inserting barriers to re-use and modularity everywhere in technology, particularly software.






Those are some good examples, more of that please. Most of the lithium powered devices I’m using currently are power tools and they are exclusively repackaged 18650 and 21700 cells. It’s really not much of a technical challenge to make these things standardised but if there is no regulatory pressure it’s easy money for the OEMs and more toxic waste for us.
