Aspirin in auto Batteries?

Aspirin in auto Batteries?

Aspirin in auto Batteries?

(OP)
There is a lot of folklore about an aspirin in each cell of a dead battery giving it new life.

Does anyone know of the scientific explanation for this?

RE: Aspirin in auto Batteries?

Folklore.
Auto batteries are lead acid.  Specifically lead (pB) and lead oxide (pBO2) and dilute sulferic acid (H2SO4).  Two units of acid combine with 1 each lead and lead oxide to form lead sulfate and water, releasing electrons.  Charging reverses the chemistry.  A depleted battery therefore has used up both its acid and its lead.  Addition of more acid, either battery acid or aspirin, can give a temporary boost.  But since there is no additional lead, it is TEMPORARY.
