Thanks for info. I started to read your technical section and the
lights went out but will do more studying later. I've always liked the
idea of a meter that showed amps in/amps out but never was able to
figure out a method of outwitting the time necessary for the chemical
changes to take place during the charging phase.

Hi,

Just google for 'battery conductance tester', that's basically what it
is.

Whether it's worth having or not IMHO depends largely on whether the
prospective user knows little about electrics and isn't able to use a
hydrometer.

cheers,
Pete.



Pete, do you propose using a hydrometer everytime you want to know your
state of charge? This could be a couple of times each day, or more.

It is, or used to be, the practice on submarines. Not much extra work
when you are checking/adding water. The original smart charger was a
sub sailor with thermometer, hydrometer, and voltmeter. Who knows what

those guys are doing now.
