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.
