[ale] Where2Dispose UPS batteries ?



The chemical process erodes the lead from the plates, but when it's
reclaimed, they get some lead out of the electrolyte solution (minute
amounts, and some from where it has plated out on other components where
it isn't useful. The lead doesn't disappear, it essentially just becomes
"disconnected" from the grid, and so can't carry any current.

Once it's resmelted, it is not chemically pure lead (Pb), but is quite
usable for manufacturing batteries. It will be reformulated into lead or
lead oxide paste, and pasted into the grids, which are the support
structure. The grids are what need to be made of the better grades of
lead, and are the only real hard lead structures in a battery.
