After reading WA1MIL's wonderful article on modifying NTN4633B chargers
(reducing the trickle rate and reverting to trickle on power-up with a charged
battery), I have a coupl of questions for the group:
(1) The article stated that this mod essentially
upgraded chargers from a "B" model to a "C"
model. I was wondering what the difference
between the "A" and "B" models were.
(2) I attempted to duplicate the "power-off" conditions
with a "C" model I have (fully charged battery on
"green" trickle charge, pulling the plug, and
expecting it to revert to "green" trickle when
power re-applied) but the charger goes into
quick charge more.
So, are these mods really more that what a "C"
model has in it or what?
..do I make sense, and thanks in advance for your responses.
(Also, great article, by the way!)
