Today, is my third trying to build a=20
universal battery charger.=20
I don't have one, that can charge
my pile of batteries!!!!

I tried lm3647, max713 both have=20
-dV termination. But I never got=20
even once to have my battery=20
fully charged! They seems always
terminated far early than 1/10 of
whole time.=20

After check and check, I realized that
-dV sensoring is such high demanding
circuit. There are plenty of -10mV signal=20
come as interference. To, -dV performance
of battery charging, only exists on paper.

I prepare to give up using -dV termination.
I can only try to build a pic time-current accumulating
charger. that should be better immune to noisy.=20

So, what are you guys using now?=20
never saw the question been raised,=20
or you all have never being bothered=20
by charging battery?
