16 Volt?

[Ed Van Scoy <edvs@idt.net>]

One of my problems at Speed Week was a weak battery. I don't run an
alternator, just a fresh-charged 12V Optima battery. Some of the 1/4
milers use 16 volt batteries & I was wondering if this was a good choice
for my Vette and would welcome opinions.  The electrical components I
run off the battery are fuel pump, MSD and electric fan. As a side, I
have gone through 3 "gel" batteries in the last 7 years, coincidence?
