Shhh... Don't confuse Larry with facts...

Nope...solid lead. Drill a hole in one some time....

Great conductors. Don't think so? Take a short piece of #000 welding
cable and just short out the terminals and watch it melt the wire, if the
battery's good. Takes 50-150 amps to crank the car...more in cold weather.

If the lead had any appreciable resistance, it would melt the terminals and
the inter-cell jumpers, also made of lead inside the plastic between cells.
Lead melts at quite a low temperature...it's soft to start out with.

<http://www.enviroliteracy.org/article.php/249.html>:

Lead is a naturally-occurring chemical element that is toxic to humans.
Known as (Pb), lead's scientific name and symbol are derrived from the
Latin word plumbum meaning "liquid silver." A malleable, bluish-white metal
with POOR ELECTRICAL CONDUCTIVITY ... [emphasis added]

Because lead is such a poor conductor, in electrical applications it's
commonly alloyed with copper; i.e., that's not pure lead.

I called the person who asked me about this question in the first place.
His line has been disconnected. I never got to give him an answer, but best
was for him to fwd his calls to the landline wired into the lead room. That
will work all the time. Thanks for the dialogue... learned some. dr
