We need to have one of the electric gurus take the plans and scale them up
so that we can pulse in less time.
http://www.homepower.com/download2.htm has the free plans for a mid-sized
unit.
We need a more powerful unit like the large Pulse Tech units.
Anyone out there that can scale up the pulser circiut so that we can polish
a big bank all at once?

Arild comments:
Increasing the power of the pulse is not necessarily a good solution.
The pulse technology device is in effect a very small transmitter which
produces RFI.
When you increase the output power you also increase the range of any RFI.
This RFI can cause interference in any number of other elecrtonic equipment
such as radios, navigation gear, your Differential GPS beacon receiver and
even your entertainment radio and TV reception.
I have a Guest charger which totally wipes out my television reception, and
causes noise in the background when I turn on my radio. This charger
appears to use some form of pulsation in its normal mode of operation. It
certainly wouldn't be my first choice as a battery charger. However it is
part of my ongoing test setup.
Don't make the mistake of equating power with speed. As far as I can see
the bigger PulseTech units are for dealing with more batteries in parallel
at a time and also to provide a charging current. The basic pulse unit does
not charge but can desulfate a big battery as well as smaller units.
PulseTech told me that they do not have an interference problem now,
precisely because of the low power output.
From another source I learned that early PulseTech units did create some
interference.
That characteristic would prevent the device from meeting FCC Class B
requirements.
Once you have brought a battery back up to full capacity, you only need a
very small amount of power to maintain the battery in a sulfate free
condition.
If you install the pulsator on a fresh battery, a small unit will keep that
battery desulfated.
It is the impedance of the connecting cables and the electrical harness that
necessitates installing the desulfators directly onto the battery terminals.
While you can connect two 6 V batteries in series to make one 12V cell, and
then use one 12V desulfator; you cannot get good results by hooking many
12V batteries in parallel and then hooking one desulfator across the
whole bank.
