Default Battery Electrolyte..

95% of the batteries no longer have openings to pour it into, which is a

I don't know about VERY, but gloves and goggles are called for, and a
plastic apron isn't a bad Idea. Stuff is harder on clothes than on
skin.
Adding acid to a dying battery is NOT a solution as all it does is eat
holes in the already eaten away plates that are left...give you a false
gravity reading without the real capacity to back it up.


You add acid to only to replace spillage. Add stuff just like what is
there, same specific gravity. Cover the tops of the plates.

The original acid load always disappears due to lead sulphate
crystallizing, making the acid unrecoverable...which also makes the lead
unrecoverable. Acid is not consumed, unrecoverably, for any other reason
unless you boil it out.


It has a pretty high boiling point. 338 C, 640 F, for the pure stuff,
[which does not help this discussion much]. The water lowers the
boiling point. Is boiling the acid common? That has to be bad . Lot
of corrosion around many batteries in cars, so acid does seem to
escape.

It does not need "replacing" like water, that is
converted into hydrogen gas, is.


And they make them so you can't add water. *******s.
