The difference is that a bunch of trinkets have lithium batteries in them and are very difficult to remove, whereas it's mostly vehicles that use lead acid batteries and they're designed to be easily removed. Also you tend to replace lead acid batteries and continue to use the product while with lithium you tend to throw out the product when the battery is dead. This combination makes recycling much more difficult, although I'm sure you'll be able to catch most of this with general electronics recycling.
Well nobody tried to use lead-acid batteries for storage of anything on the significance of grid base-load and replacing a huge chunk of transportation energy capacity.
For decades we have used lead-acid batteries in close to every backup power solution of any size, plus at least one lead-acid battery per vehicle. Of course we expect lithium-ion to surpass lead-acid in market size and number of deployed batteries, but the amount of lead-acid batteries in the world is nothing to sneeze at either.
