Bill, sorry, but I think this is too simplistic. For this analysis to apply, you'd have to assume that essentially every lead battery manufactured replaces an existing lead battery. Obviously that's not the case, so of course some newly mined lead has to enter the manufacturing stream. To name only one reason, each year the vehicle population worldwide increases about 3.5 percent. The vast majority is ICEVs, but almost every one of them has a lead battery. At the same time, the 98 percent figure has always struck me as implausible. I've seen too many explicit counter-examples, such as the coast guard workers I read about who (at least used to) regularly tip spent buoy batteries into the deep so they wouldn't have to haul them back to port. Do you work in an office? In the years I worked in a place that had a UPS at every computer workstation, the number of batteries I rescued from the trash and took home to my own recycling pile numbered in the dozens. I'm sure I probably missed the majority of them. It's also shocking to read the harrowing accounts of third-world battery recycling. Apparently it's cheaper to export some batteries and other recyclables to low-wage countries for dismantling. In many cases these nations have weak or nonexistent environmental laws, or the laws can be bypassed with a small cash payment. Thousands of dirt-poor people work in these gigantic festering scrap piles, with no protective gear, poisoning themselves and their air, water, and ground day after day. How is this accounted for? Do we ignore it because they're lead-polluting some other country, not ours? And shouldn't we consider the impact of shipping the batteries over, and the reclaimed materials back? Sure, there's a well developed recyling infrastructure for lead batteries, and thank goodness for it. But what are the consequences for not using it? Nobody is checking your trash. In the end it's down to individual responsibility. Good luck finding much of that, outside of folks on this list. I've seen this 98 percent battery recycling figure many times over the years. While (as the song says) data is not the plural of anecdote, my own observations, reading, and experience make me skeptical about it.
