convert atx power supply to car battery charger

[@tndaryl840]

*This battery reconditioning program exceeded my presumptions. It worked on any drill battery, several AA and AAA batteries, **batery.repair** and any camera battery. The steps are simple and the act itself is exciting to do. No matter what type of battery you`ve got, it is sure to function again!*

Despite the language barriers, you did an excellent job that everyone, except the average american, can comprehend. Thx

Oh, I really thank you

Alfred increíblemente sencillo tu tutorial, gracias por compartirlo. Para los que les interes y tengan una red domestica de 110V reemplace la resistencia de 7ohns por una de 14ohns. Alfred incredibly simple your tutorial, thanks for sharing. For those who are interested and have a 110V domestic network, replace the resistance of 7ohns by one of 14ohns.

[@AlfredH]

thank

[@abidinismailov9158]

Does the size of resistors (watts) matter? because I put small watts and when I plug 55w halogen lamp and the power stops. ?

[@genesisrobles3426]

I feel thankful this reconditioning plan kzbin.infoUgkxcJ22tnHH9l1vjdIdEIG27iOG55P7LXI8 was founded. I was just about to throw out Three old batteries that I thought were completely dead. Having said that, I tried reconditioning them and it took me less than an hour to acheive it! No matter what type of battery you like, the procedure will work.

i dont know what you saying but understood what you doing great video !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I use 27k Resistor on my Salpido 500W power supply and I got around 13.5v 24A

[@AlfredH]

ok

[@chetan26726]

Which pin ? I have 7520 ic

[@amabonds]

Using the 10k alone enough?

[@chetan26726]

Which is two resistance add on ic wt7520 pin number 16 ?

[@amabonds]

Will using the 10k alone be enough to increase the voltage to 13v

Although I am late viewer of this video but its very informative, THANKS a lot.

hi alfred...i have a psu and the ic is J04M82 but no manufacturer's name on the ic. what video do i follow to charge an APC psu battery? the battery is completely dead. help me. thanks.

[@AlfredH]

You follow another ATX video in my channel

[@newvaper3794]

@@AlfredH can you be specific alfred on what site?

[@gadyetkho877]

can i ask you if you remove any components or parts before you add those resistors? i ask you this because i saw a similar video like yours, but he removed some of the original parts of the PSU. i'm planning to make this because i have the power supply (with TL494 i.c.), thanks.

[@AlfredH]

Can you tell me what you use?

[@gadyetkho877]

....what do you mean what i use? what i have right now is a psu with TL494 i.c. which i'm about to convert it as a 12volts car battery charger just like what you did in your video. and what i would like to know from you sir is, do i just solder 7k ohms resistor to pin #16 and 2.2k ohms each to terminals 1,2 & 3. without any other alterations on the pc board of the psu, thank you very much for your reply.

[@terrymore]

What should I do for TL494L? I did not try.

[@AlfredH]

Can you ask more clearly?

[@jaymemendonca6075]

very good!! I do not understand the 2 ohm ceramic resistor to test the source. Is this resistor connected to 5V or 12V so as not to trip the protection circuit PWM ? If that is possible, I would have the. download subtitles. thank you!!

[@AlfredH]

ok, use resistors 2 OMH is to check the source of ATX. To see the number of volts can be down low?, Before providing it to the charging

[@AlfredH]

I will try to download subtitles

[@AlfredH]

you can also use to mount resistors 2 OMH serial battery charger, it will not be overloaded

[@jaymemendonca6075]

I really liked your video. Thank you very much for the instruction. Health peace and long life !!

nạp bình axit nước thì khi nạp đầy bình nguồn atx có tự ngắt ko a Hải? cảm ơn

[@AlfredH]

muốn tự ngắt thì thì phải làm thêm mạch tự động cắt điện. có ở trong kênh

[@judapitec]

yo cambie un poco el diseño y observe que al incrementar la resistencia en el pin 16 tambien se incrementa el valor del voltaje de salida, por lo tanto lo unico que hice fue eliminar la primera resistencia que va conectada al circuito desde el pin 16 y remplazarla por una de 20K espero les sirva

[@limestežika-nuli]

Can you tell me how to convert ATX with IC2003 in car battery charger. Thank you

[@vatroslavmikula]

Really good job, I have this type with TL494, I ask are the resistors on pin 1 and 4 of TL 494 connected to the minus pole or ground (black wire) ? After that completed is short circuit protection works normaly? I would charge car battery 55AH with max 5,5 Ampers. Thanks for answer!

[@AlfredH]

if circuit protection is still active then you can be connected in series via a resistor 1-2 OMH 5-15w for charging batteries

i want to charge my car bettery with computer power suply.

i successfully modify my computer power supply but i am facing one problem when i connect power supply with battery(12 volt 80Ah) terminals (power supply positive red wire with battery positive and black wire with battery negative) fuse blows (which is connect with positive wire 13.4 volts). i tried 2amp, 5amp, 10amp and 15amp rating fuses. how to control charging current. i think there is no current limit in charging that's why fuse blows. thanks.

[@AlfredH]

You can use a small round ferrite core, use 1mm copper wire wrapped on 2 or 3 mounting rings to reduce the number of Amp as you want.

can i use 2 10k resistors and 1 5k resistor for 25k at least will 25k work anyways?

Can I use only the 10k ohms

ok you can use 10K ohm. If the output voltage is not satisfactory, you can add a resistor in series

Hello; Tthank you.

That runs by 12v 200w. My idea is generate electricity with mown engine. Whitout use convertor 12v dc to ac 220. I would like to use 14v for power on asic directly whitout power modules. (220v 1600w) Can i use Atx to convert 14v to 12v with 20A or higher? I need a circut for this convert. For lower cost. My asic has 4 of hashboards. Are the voltage and Current damage hashboard? Is it possible? What is your proposal?
