I will order infinitum desulfator for 12v battery.. cause my tractor battery 12v dead.. but wanting to look inside what they made cirucit stuff.
sorry speak bad english cause i'm deaf..

This is a well regarded desulphator which you might be able to
build yourself from components:

Yeah I saw that website earlier but it may not same cause desulfator infinitum Diffence than ever however it give unlimited amp, not needed fuse and so
Hi,
This circuit is not called specifically a desulfator but still does a good job and very simple and explained:

Very interesting. Can u give me part lists? I will learn basic circuit quick. Used to repair mobile power & tv cause bad caps
Hi,
René made this circuit and I found his post at another forum where he showed separately the schematic as in his video. This is the link to his posts: http://www.energyscienceforum.com/alternative-energy-general/322-re-emf-charger.html (http://www.energyscienceforum.com/alternative-energy-general/322-re-emf-charger.html) and I attached the schematic below from the other forum where you cannot see it unless you become a member there but you can read his posts.
In the schematic you can see the components, basically the circuit is a Joule thief, you need to get a toroidal ferrite core and wind a bifilar coil onto it. See this photo how the bifilar coil on the toroid looks like: http://www.overunity.com/6123/jule-thief/msg141376/#msg141376 (http://www.overunity.com/6123/jule-thief/msg141376/#msg141376) René suggested about 30 turns bifilarly onto the core. From the different wire colors you can figure how the wire endings should be connected.
You can get toroidal cores from discarded computer power supplies or from different sources like this:
http://www.goldmine-elec-products.com/prodinfo.asp?number=G16214 (http://www.goldmine-elec-products.com/prodinfo.asp?number=G16214)
The transistor can be 2N3055 and the 3 diodes can be UF4007 types. If you need to use the diode bridge shown on the left hand side, use 1N4007 or any rectifier diode good for 12V AC max 1A. The puffer capacitor for that diode bridge can be at least 1000uF 35V.
In the transistor base circuit you need a 330 Ohm at least 0.5W resistor in series with the 1 kOhm potmeter (this latter can be linear or log).
By the way if you have wall plug-in power supply with 15V to 18V DC output voltage and say some hundred mA current rating it will be good for feeding this circuit. Or if it has AC ouput, you may use the diode bridge and the 1000uF puffer capacitor.

can you give me make ready to order list parts. please thank :P
Well, can you tell which of these or other component sellers work in your country?
for instance http://www.farnell.com/ (http://www.farnell.com/) http://www.digikey.com/ (http://www.digikey.com/) http://www.rs-components.com/index.html (http://www.rs-components.com/index.html)
http://www.mouser.com (http://www.mouser.com)
and of course there are many others. IF you can locate any such component seller in your local area or in your country, you may wish to name it?

Can u give me all of it number part lists. It will save me time cuz I'm at work
Hi,
Here it is
1 quantity 2N3055 npn transistor
1 quantity 330 Ohm resistor 1/2 Watt
1 quantity 1 kOhm variable resistor or potmeter
3 quantity UF4007 diode
1 quantity toroidal ferrite core OD 12mm to 25mm
IF you do not have a wall plug-in mains power supply with 15V or 18V DC output you also need such. OR if you have a mains transformer with 12-15V AC output, max 500mA load current it is also good, for this latter you need rectifiers:
4 quantity 1N4007 diode
1 quantity 1000 uF /35V DC electrolytic capacitor

Thank you very much I think do have old power supply Pc & will find few more old wall plug

can you give me link parts all is digskey .. cuz there too many number diffence just wanted to make sure right you know what i mean? :P.
i found core on broke tv lcd i think
Hi,
1 quantity 2N3055 npn transistor http://www.digikey.com/product-detail/en/2N3055/497-2612-ND/603637
1 quantity 330 Ohm resistor 1/4 Watt http://www.digikey.com/product-detail/en/2-1625875-6/A105936CT-ND/3477500
1 quantity 1 kOhm variable resistor http://www.digikey.com/product-detail/en/93R1A-R22-A10L/93R1A-R22-A10L-ND/2564718
3 quantity UF4007 diode http://www.digikey.com/product-detail/en/UF4007/UF4007CT-ND/965732
Should you not find toroidal ferrite core, here it is:
1 quantity toroidal ferrite core OD 20mm http://www.digikey.com/product-detail/en/B64290L0632X830/495-3864-ND/1830194
Should you have no wall plug-in mains DC supply but with 12V-18V AC output only, you need these to rectify AC output:
4 quantity 1N4007 diode http://www.digikey.com/product-detail/en/1N4007/1N4007FSCT-ND/965481
1 quantity 1000 uF /35V DC electrolytic capacitor http://www.digikey.com/product-detail/en/ESY108M035AL4AA/399-6120-ND/2712532
OF course you need enamelled copper wire to wind about 30 turns bifilarly onto the toroidal core, roughly at least 2 meter in length, wire diameter could be anything from 0.3mm to 0.6mm (roughly awg #29 to #22).
(You may also try this as I indicated earlier: http://www.goldmine-elec-products.com/prodinfo.asp?number=G16214 )
good luck.
