(For reference, phone batteries are more like 20 watt hours)
Every other source I found talks only about EV batteries (including scooters and bikes) regardless of capacity + industrial batteries >2kWh.
Edit: Given the discrepancies and vague wording of the article, it sounds like corp-blog slop (doesn't matter whether it was hand-crafted or AI written, slop is slop) that shouldn't be relied upon. HoldMyBill is some kind of receipt management app, not a web site that explains laws as I initially thought.
I have mixed feelings about this for scooters. They started out as low friction, low regulation, very low cost means of transport. Adding bureaucracy to them might create more friction/harm (by increasing cost/reducing accessibility) than the benefit of reduced friction when selling used ones. OTOH being able to buy a used one with some confidence that the battery is still usable would be a huge benefit of course.
