Melt in warm distilledwater 10 teaspoons Epson salts, distrubute equally into cells of a 850 amp hr battery    cook   2amp   discharge to 9volts  recharge at 2 amps    lead sulfation is GONE!   can repeat this around 5 times over the years       ))   GL  if your battery is different size  multiply diminisions and compare to 850 amp battery to get a ratio that is correct for your battery.  ))   Your battery sounds like it is shorted in one cell (prob is normally in most negative cell, perhaps a total dumping and refilling will remove that crap in the bottom that can short your plates, then clean the plates with the mag sul (epsom salts), BEWARE!!!! Your fluid is an acid!!! Treat it like poison dont get it on you or anything you want to keep!  Filter the fluids and reuse or replace with fresh electrolyte

@All,

Sorry, I have not been monitoring this thread for a while.

@totoalas,

I have sent you a email.

@luishan,

The arrow on the resistor means that this is a variable resistor (potmeter).

Hi,

I am new at forum and i searched for good battery charger and i found that topic. I saw a drawing that added "groundloop" (at first page of this topic) with trifilar air coil and one thing interests me most - do i need some oscillator or other device to get some frequency to charge or just by using 1 k pot?

Hi Topper,

Build the circuit as described in the drawing. Do not change anything.
This circuit will self oscillate, no need for anything extra. The BUX80
is hard to find these days, but the BUX98 is still in production (as
far as I know) and can be used instead. Other power NPN transistors
on heat sink can also be used.

Hi,

I searched in Poland for bux80 and i found that tranny about 5 $:).
http://inelsc.pl/pl/p/Tranzystor-BUX80/2448

I like ure design of charger its simple. I builded a circuit below but the coil is hot as hell so i abandoned it.
http://i291.photobucket.com/albums/ll303/TEEP_photos/DSSC.jpg

I read that u use 1mm thick wire so u can charge higher current.  I have three spools of wire 0,6 mm for making trifilar coil. I will be using plastic tube but at other dimensions as u posted about 160 mm diameter and please advice what should be resistance of single wire of trifilar coil to work properly. If i know resistance of coil i will know how many turns i should make?

Topper,

If you use two strands of your 0,6mm enameled copper wire in parallel
for each of you three coils, then you will have thick enough wire in total.
I do not remember the dc resistance of the coils now, sorry, but if you
use approx. the same number of turns as posted in the circuit drawing
then the circuit will perform fine. It is not a critical design at all.

Hi,

Ok i understand trifilar coil with 3 wires that every has two strands of 0.6mm give us 6 filar coil and lot of work:). Two strands for carry the bigger current.
But bigger current wont cause the coil or transistor very hot? I thought to use only tree wires of 0.6 mm not doubled for lower heating. Will it work with that circuit?

And this circuit i cannot control how fast and how big current the battery is charged. Lets say i want to charge smaller batteries than 60 Ah ( 7 ah, 18 ah). Could be worth of putting instead of "R2" -500 ohm 4 watt potentiometer?

Any help is very appreciated:)

Topper,

Use a heat sink on the transistor. You can increase the value of the potmeter
to 1k to get a lower output from the circuit. You can use 0,6mm wire if you want
but there is a probablibility for wire heating at higher power. (Thin wire will heat more
than thick wire if you send high current through them.)

The BUX80 is hard to find these days...

There still arround though,
I just got four off of eBay for $5,
$10 for all four delivered actually.

They are out there as NOS (New Old-Stock),
mine were from a retired repairmen as example,
they are even the good (RE: original) Philips ones.



EDIT:
I have written Fuji Semiconductor about another part.

You can find them on eBay as this:
"300V 20A Super High Speed Rectifier"

They come as a common cathode diode pair
in a handy TO3-P sinkable casing style.

Their simple name is roughly D92-02, D92-03, Etc.,
but they come with up to four letter prefix's,
and a few letter's worth of special part suffix's too.

I have written them asking for the part numbers for
the complimentary-opposite common-anode version
that would allow simple (two part) FWBR's for us.

These are slick,
and catch more of a coil collapse spike than many...



Your's are a good pick too (BYV29-500),
and only $1.37 each at Newark as example:
http://www.newark.com/jsp/search/productdetail.jsp?SKU=70R3667&CMP=AFC-GB100000001
But they are mid 60's in nanosecond recovery, pretty good,
but the D92-xx series is mid 30's of nanosecond recovery.

They are also the same buck-and-ahalf (US) or so in price...

Every bit helps.

Hope this helps.

Attached is a image of my unit.
As you can see I use two transistors in parallel
so that I do not need a very big heat sink.

Um,
how the heck did you squeeze a 12 centimeter coil in that box, heheh ?

CompuTutor,

I did not take a photo of my first prototype. This is the second
unit I did build. In this unit there is a ferrite rod with coils. So less
turns and more compact coil/core. I posted the first circuit drawing
because it is less fuzz to make a air core coil and most people
does not have any Ferrite. Soooo........................heheh

Groundloop

Been scratching the web for a decent battery charger, thanks for a simple yet effective design,

Do you get the same radiant type spikes as with the Bedini systems ?

Would you bewillig to part with the specs (core diameter, wire gauge and turns, etc) on the ferrite core on your second charger in the photo, would just make for a much neater/smaller setup. I have some lengths of ferrite core laying around that I can utilize.

@Virus,

It been a long time since I made this circuit but if my memory servers me well then
the L1 and L2 coils was approx. 100 turns of 0,5mm enameled copper wire. I did
drill holes in the metal top cover of the box to fit two MJE15003 TO-3 NPN transistors.
I did open up the box today and made the attached circuit drawing based on the
the way it was soldered together. I did measure the Ferrite rod and found it to be
10mm in diameter and 25mm long. The finished coil was approx. as wide as
it was thick. Everything was soldered together in a "rat nest" fashion inside the box.
I run my circuit from a mains power supply that gives 9 Volt at maximum 1 amp
to the circuit. The output diode is a 1000 Volt 10 amp diode. It is like a 1N4007
on steroids. :-) The circuit do make a lot of high voltage spikes at the output and
I have found the circuit to do a good job of de-sulfate batteries. I did build this circuit
to charge my 12 Volt 7 amp gel batteries. There is not much output when you try to
charge larger batteries, it will take too much time. But for smaller batteries the circuit
works very well. Hope this answer your questions.

GL.

Thanks for the effort that you put into getting the info from your system, very much appreciated, I think a lot of other people will also benefit from it,

What would be the biggest battery (you think) that can be charged effectively with this circuit, from my little research it seems the bigger the coil the bigger battery/bank you can charge?

I want to build up a battery bank system (systematically) that will eventually supply enough to run the whole house, and is currently looking at different charging option, Bedini, solid-state, magnetic/rotory systems etc, any idees from your side, what would be the most effective?

Thanks

@Virus,

The largest battery you can charge in a resonable time frame,
for the circuit posted, is a 12 V 14 A/h battery.

I can't give you an advice for a battery charger at that size. But I recommend
you look at the net. There is many good inverters that has a built in battery
charger. These inverters will give you a true sinus mains power.
