hi . please forgive my ignorance . i see three wires connected to capacitor . two on one end i have no idea where they go . can anyone explain how this is wired . and how it leads to battery . we desperatly need to save batteries here in a our secluded area in high atlas morocco . we can't afford new ones . thank you so much .
I made one on 220v it ok I charged two cord rill battery, and few car battery. Today I gona bild one with 10mf. BTW I conec to him 1000hz desulfator and is ok its work ok no problem so far. Once I had electrical shock 315v 16mf=1,3A and suvave. BE VERY VERY CAREFFUL use protection and fuse. I only use to trickle charge the battery to have enough energy for 1000hz desulfator.
i tryed to get the sealing lit of my sealed coldax battery to fill the acid level but i cant get the fricking lit off!!! i have to fill it cuz its half full with acid but it doens't wanna get open i tryed with screwdrivers but its stuck! do you have any idea how???
6 car batteries with different amp hours should be in series, NOT parallel. The worst battery will "suck" the other ones down. You can keep it hooked up for two weeks as long as the voltage doesn't go too high. About 1 amp or less will usually work for the current. At 15 volts max each, if the voltage gets above 90 volts or so, you will need to disconnect it.
i found a battery a week ago and its not really old a year or so and when i put my volt meter on it it gave 0,01v so i puted it on my charger and 0.00 amps current but after 3hours i had 3amps and after 3days charging with 6amps it was charged.. and give 13v+ is a Q-cell t8-orange do i have to desulfate it or is it fine?? and when i hold it upside down i hear :blublub blablab.. its maintainece free. so is it possibe the acid levels are low??? plz comment back!=D
@KRAYSLiCK999 i think he has put a capacitor on mains ac 120volt in series on +eve. by which he controls the current and voltage, smaller the capacitor smaller voltage and current it passes ahead, this way by changing capacitor he can change voltage,
after lowering voltage through capacitor in series he has diodes from old wan which ratify ac in to dc, this way he can directly charge a battery just by using single capacitor and diodes.
This is frustrating as hell. I bought a desulfator off ebay, but I can't figure out how to supply a trickle charge to the battery using a wallwart. I try 12vdc 500ma + to +, - to -, and as soon as I hook the wall wart up to the battery I heart bubbling and boiling, and I get sparks, and sometimes the wires smoke. I can't use my regular digital charger because it shuts off with a red light and won't charge if the damn battery voltage is under a certain level. Bats at 10.9v,11.04,11.91v
@cobrachoppergirl The transformer type usually are very simple and don't have any smarts. That wall wart may be designed for something that is really 13 volts, and since the battery is so much lower, more current flows. You need to use my circuit and use a capacitor that will provide 250 mA or a little less.
how can you tell if a battery is sulfated? because i have 6 eight volt golf cart batteries that wont charge all the way and runtime is low. how would i diagnose them?
Excellent ! If you look at the first battery chargers, they are not much different.
Lead acid prefer choppy charge current to smooth anyhow, and the modern pulse chargers are little more than PWM power supplies without a smoothing capacitor.
I agree with most of your video, however from my experience the heavily sulphated batteries need extremely low current at first. What seems to happen is that the current density on sulphated plates is not uniform, so some localised areas may be gassing early. Over here in the UK the mains is 240v single phase in typical resedential properties so this does get a bit dangerous. Power factor correction capacitors out of old flourescent light fittings are ideal for this though.
the power supply is 120 vac. It then goes through a Run capacitor and then to a full wave bridge. To see more, go to my blog (poormanguides(dot)blogspot(dot)com)and go to May 14th posting called Updated Charger/Desulfator
good job. I always hook up one of those timers to it and let it run. The cool thing about the charger is that it will put the amps through the battery even if it has to put out 170 volts DC to do it. 120 volts AC is really 170 volt peak, so DC can go that high. I've never seen it go that high, but once it shot up to 70 volts and then went back down.
Richard, I built your Charger/Desulfator and it works great! I used a 45mf in parallel with a 10mf capacitor. My goal was to recover 9 Dewalt cordless drill batteries and it did the job. The batteries were 7.2v to 14.4v. These were batteries I had given up on. They had all been dead for over 2 years in my shed with the heat and cold. I finished the charging with the Dewalt charger cause I don't know how to tell when they are fully charged with your charger, I didn't want to burn them up. Thanks!
I don't think so. These are the "run" capacitors that hook to AC induction motors. They have metal cases and are filled with oil. They are usually about 20 to 30 MFD but can go up to 100 MFD (microfarad)
Capacitors found in microwave ovens are similar in that they are also oil--filled capacitors, but they are rated for a much higher voltage and less capacitance than motor run capacitors.
As such microwave caps should work but you'll have to put several in parallel to obtain enough capacitance.

@rclewis01 yea right, connected in series each battery will be fully charged with only 2V...

Hi Richard Lewis I made one of this for 220v my question is can I live it to battery permanently linked for 2 weeks.
I have six 12v car battery in parallel with different Ah is it safe to leave all the time ON for 2 weeks

if i use a 24 mfd capacitor I get 1 amp. If I use a 2 mfd them i get 1/12th pf an amp. AC + capacitor = comstant current

hey MAN I NOTICED THERE IS NO TRANSFORMER THERE?? how is it possible 115vac to 12vdc?
KRAYSLiCK999 11 months ago
@KRAYSLiCK999
thats right.. you are charging the battery with 120v mains power.. just rectified and current limited

Best method in your case would be take a parallel out of your Computer UPS to charge any 12V Battery.

Are you using 117v to charge a 12 volt lead acid battery? I hope your life insurance is paid up.

Why not just use a solar panel as your power source? would be a little more interesting. Greetings from sunny Jamaica.

so U can charge the 12V battery you R using in the system? therefore your 12v batteries r always charged?
