The Lead Acid battery is made up of plates, lead, and lead
oxide (various other elements are used to change density,
hardness, porosity, etc.) with a 35% sulfuric acid and 65%
water solution. This solution is called electrolyte, which
causes a chemical reaction that produce electrons. When you
test a battery with a hydrometer, you are measuring the
amount of sulfuric acid in the electrolyte. If your reading
is low, that means the chemistry that makes electrons is
lacking. So where did the sulfur go? It is resting on the
battery plates and when you recharge the battery, the
sulfur returns to the electrolyte.

1. We must think safety when we are working around and with
batteries. Remove all jewelry. After all you don't want to
melt your watchband while you are wearing the watch. The
hydrogen gas that batteries make when charging is very
explosive. We have seen several instances of batteries
blowing up and drenching everything in sulfuric acid. That
is no fun, and would have been a good time to use those
safety goggles that are hanging on the wall. Heck, just
break out your disco outfit. Polyester is not affected by
Sulfuric Acid, but anything with cotton will be eaten up.
If you do not feel the need to make a fashion statement
just wear junk clothes, after all Polyester is still out of
style. When doing electrical work on vehicles it is best to
disconnect the ground cable. Just remember you are messing
with corrosive acid, explosive gases and 100's amps of
electrical current.
