The subject of what happens to old lead acid batteries applies of course to everyone with a car, not just EV owners.
But since EV owners go through so many more PBA batteries than the average person (well, in most conversions anyway - not counting other chemistries), what happens to those batteries is a topic that interests me.
I don't know if people outside of Canada will be able to view this, but I found a video from the program "How It's Made" that shows the car battery recycling process at Exide.
It gives the impression that the battery is nearly 100% recycled: plastic is reformulated into new battery cases; the acid is chemically neutralized; the lead is recycled into new plates for more batteries.
This may only work for Canadian IP addresses. Let me know!
