battery datasheets always recommend three phase chargers as the best
type of charger. Approximately...

Phase 1: constant current until 14.5 volts is reached
Phase 2: constant voltage 14.5 until the charge current drops off to 2%
of amp-hour rating (e.g., 7 AH x 2% = 0.140 amps)
Phase 3: constant voltage at 13.7 volts

But, I'm not aware that they do any harm, either.

Hi Eric,

I'm curious, what brand and model number charger do you use that offers
those 3 charging phases. I may be interested in selling them if I can find
a good product at a good price.

I sell the Xenotronix charges. They have proven extremely reliable and seem
to take good care of glider batteries. I think they are 2 stage (phase)
chargers.

I sold the BatteryMINDer desulphating chargers for a while, but they didn't
sell well. They are more expensive and it is unknown whether they really
make batteries last longer.

I sell the Power-Sonic batteries and have had good results and feedback on
them.

I've been using the Power Sonic dual-rate, automatic charger
(PSC-12800A-C) with satisfactory results. Ultra-simple, inexpensive
and foolproof with the automatic float/trickle mode. Over-charging is
impossible. Although I don't take my batteries down very far and they
never sit in a discharged state. So a lot of my success is due to my
use/maintenance habits, not necessarily the equipment.

Hi,

Those Power-Sonic A-C (A.K.A. "C") series chargers do look interesting. I
like that they work with a variety of AC input ranges. I found a different
(newer?) version of the same brochure he
http://www.power-sonic.com/images/po...s_10_Dec_1.pdf

It is also interesting that the Power-Sonic A-F Series charges includes
charges that look identical to the Xenotronix chargers I sell. I which
brand private labels them from the other manufacturer.

I need to check into pricing with my Power-Sonic rep.

Very reasonable prices, many choices for batteries and chargers.

Free shipping if you order over $75

I use a Xenotronix 4 amp charger - 10 years now. They say they are "two
stage", but their operation is usually called "three stage" or "three
phase". They have the phases I listed: constant current, charge, float.

The Batteryminder 12 volt, 2/4/8 charger seems good, and though I
haven't used one, some motorglider pilots like it. I like the selection
of currents, which fits the different batteries I have.

Hi Eric,

Thanks. I'm a little surprised you use the 4A charger. The largest one I
sell so far is a 2 A charger. Are you charging multiple batteries with the
same charger at once? Or do you have a very large capacity battery?

Best Regards,

Paul Remde

Yes, the PowerSonic "A-C" chargers work the same way. There's really
three "phases" even though they call them dual rate.
