Despite decades of evidence on the toxic effects of lead battery recycling, companies opted not to act and blocked efforts to clean up the industry.

Misleading headline making it sounds like all battery recycling poisons people. Half assed battery recycling is half assed.

Also sodium ion or some other lead-free formulation will likely replace lead acid 12v batteries over the next few years.

The advantage lead acid has for ICE is that it can dump a lot of current all at once. The C output rate on sodium ion isn't that high, IIRC.

There have been lithium batteries used for the purpose. The original Miata used one because standard lead acid cells caused corrosion issues in the chassis. But lithium has its own supply chain issues.

Ultimately, this goes away because ICE cars go away.

Me wondering how ICE is tracking people through their car batteries when I first read this 🤔

I thought they meant that the rapid high current output of lead batteries was better for torture.

12 volts doesn't really hurt much is my understanding. I think movies exaggerate it. It tracks because people literally lick 9 volt batteries to test them. The 120 volts AC in the wall would be more useful for that.

It's the additional amperage that makes the 12v worse

[–] JackbyDev@programming.dev 4 points 3 weeks ago (1 children)

Batteries don't have amps, they have volts. The resistance of the things they're touching determines the amps.

A shocking revelation!
