I also would like to learn more of the pulsing
technique -- technical details such as pulse
width, frequency, and amplitude.....
If anyone knows a patent number I can look up
it might be handy also.
Thanks........... Andy in Dallas

Its been around for a while, although not quite as long on the alt
energy front. I have seen AC battery charger/conditioners with pulse
charging for some time now.
It does make sense though, after all why can't one frequency break down,
I know a range of frequencies can weld materials together (worked in the
ultrasonic welding and cutting engineering field for a little while).
Although, I would wonder about that frequency shifting leaking thru the
whole power system as some kind of noise.

Pulse Frequency Sweep: 10,000-100,000 Hz
Pulse width @12V: 50%
The Power Pulse is fixed frequency and I think the exact freq. is
patented. I don't know what it is though.
Please note that these pulse desulfators have nothing in common with the
PWM(pulse width modulation) concept in battery charge controllers.

Have you had an actual negative experience with either PowerPulse or
DeSulfator to indicate that they only provide temporary relief? If so I
would like to hear more about it. Also, when you said "temporary
relief", it could mean a year, 2 years, 3 years, or a month, 2 months,
etc. You know what I mean? Just what exactly did you mean by
"temporary"?

My only complaint is that I think the units are over priced. They aren't
that complicated, and I would guess the profit ratio is quite high.
Possibly with competition that will change.

If you are happy with your current de-sulphation cures use them and ignore my
previous post. My comments are based on 23 years experience designing,
installing and maintaining Marine Radio Navigation solar power supply systems
and Solar Radio Telecommunication power supplies. I have never been able to
satisfactorally recover sulphated batteries. (By this I am referring to
batteries that are approximately 25% or greater sulphated ).
Also for general info I run the bulk of my house on a combination of solar and
wind power. I have 700 watts of solar panels and a 200 watt wind turbine that
charge a 660 amphour battery bank (660A/H @the ten hour rate), which feeds a
pure sinewave 24V to 240Volt 3.5Kilowatt inverter. The batteries and inverter
are Australian made (although I have modified the inverter to lift the
efficiency from 93% to 97%). The wind turbine is British and the solar
regulator is my own design.
How much does your de-sulphation product cost? and how do you determine value
for money?

You got 97% out of a pure sine inverter at 3.5 kilowatts??? DUDE! Let me
guess, inductors the size of a briefcase and about 100 paralleled
MOSFETs? Could you share the secrets?

The units I'm looking at cost around $75 each, whereas my new car
battery only cost me $40 at Costco. From a strictly cost point of view
there is never any reason to buy a sulfate remover for cheap car
batteries. I'm not going to argue with that. On the other hand, many,
if not most, people who are fans of renewable energy sources care more
than just costs. I want to be able to keep my car battery in operable
condition for many years, not because I want to save a few bucks, far
from it, but because there is a sense of experimentation, a sense of
suspense, a sense of excitement, a sense of anticipation, and even a
sense of accomplishment in seeing that a battery that can normally last
an average of only 4 years can possibly be stretched to 6, 7, 8, or even
10 or more years. To me, all of those things(experimentation, suspense,
excitement, anticipation, accomplishment) readily justify the $75
cost. It's a totally illogical decision, but human beings are rarely
always logical, are we? Hopefully, with competition, the cost for these
sulfate removers will come down drastically in the next few years.
