I'm still using my crippled-up Guest charger (probably the most

Apparently it senses on one battery and charges all 3 accordingly.


That's not an uncommon design, usually termed an "echo charger."

So, since the Guest doesn't work correctly on even a single battery, I'm
looking for another. I see a modestly priced Truecharge20+ at
www.majorpower.com. It has 3 outputs but that's all they say in their
literature. No mention at all that they are independent. I suspicion
there are simply 3 output terminals, perhaps diode isolated, but sensing
on only one line.


We have a Truecharge 40+ and I've measured it's output
voltage as being different on the output 3 legs. Whether
that means it truly senses each batteries state of charge
independently, or if the batteries were just pulling a
different voltage from the same output, I don't know. FWIW
the difference was pretty small, like 0.25V or so.

I like the Truecharge 40+ and would recommend it. We use it
with a bank of 4 Gr-31 (usually interconnected) and 1 Gr-24
(always isolated) flooded type batteries, have used the
remote panel and the desulphating function, and it seems to
keep the batteries in good shape.

I tried a lot to get majorpower's attention to answer my simple question
but cannot get past a clerk which finally acknowledged my question and
sent me to a worthless url. I doubt anyone there even knows.


Oh, *somebody* knows but they might have had him snuffed
