[time-nuts] Tongue Testing battery charge levels....

Hello, TimeNutters--

I have used the "tip-of-the-tongue" test for determining
the state of charge of batteries for many years when
my bench meters are elsewhere.  The strength of the
bitter taste is proportional to the voltage and I have gotten
pretty good at estimating the charge condition of the
ubiquitus little 9 volt batteries as well as a few others
to within +/-  one volt or two.  I recommend not using
this procedure for anything over a 12 volt battery as
above that level the bitter taste turns into an unpleasant
bite.
