Thanks for sharing this video. Without making any modifications to my charger (older version of the one in the video), I got the chager to start electrolysis with a 9 volt battery. All you need is a little jump start and the charger will go on.
I don't know if anyone is reading this thread anymore, but I thought I'd leave this for posterity: I got the 2022 version of this battery charger to work. I'm using it for resistance soldering, but it doesn't matter what the end use is -- you'll get 12v out of the clamps. The circuitry in the 2022 version is indeed different from what's shown in the video. How I got it to work: there's a red wire that's attached to one side of the internal circuit breaker and runs to a circuit board on the other side of the charger. (The circuit breaker is wired in series through the meter and is mounted on the unit's base.) Remove that from the circuit breaker. I used an old Radio Shack wall wart transformer set to 4.5 vdc. I attached the positive lead of the transformer to the red wire that goes to the charger's circuit board, and attached the negative lead to the grounding plate that's at the back of the inside of the charger. That fakes the charger's circuit into thinking there's a battery attached to the clamps. That's it. The charger LED will light and you'll get 12vdc from the clamps. If you attach the wall wart backwards the red "wiring connection" LED will light. To make the unit do double duty, I added a single-pole double-throw switch and two external contact points to the plastic portion of the front of the charger. When the switch is thrown one way, the red wire inside is attached to the circuit breaker, same as normal, and I can use the unit as a charger. When it's thrown the other way and the external wall wart transformer is connected to the external contact points (simple bolts), the charger works as a transformer for m resistance soldering. The center pole on the switch is connected to the red wire inside that goes to the circuit board. One side is connected to the circuit breaker, and the other side is connected to the + external terminal for the wall wart. The other external contact for the wall wart is wired directly to the grounding plate. Works great!
Thanks man! I was getting frustrated with same charger, specifically for electrolysis, and you helped me out totally.
I got Bob Ross vibes watching this. Thanks for the video.
very nice solution to bypass the safety feature of the charger. thanks for sharing
Thanks for the video. I used a little 9 volt battery instead of the DC converter, worked great!
I was wondering about that. Thanks for the update!
Love the permanent solution and the work around is AWESOME! Thanks!
Thank you for a cheap way to get electrolysis because I have so many broken 12v chargers that I can repurpose to clean some small bolts or car parts that are rusty
How about installing the
12vdc wall wart adapter in the charger box.
Then connect the positive and negative of the wart to the pos and neg thick wires main charging cables. But have 1 of the little wart wires go through a switch?
Momentary or latching, depending on what works best for your unit
Trickle charging with the part 2 video method: Are you able to change amperage (2, 10 or 50)? Or does it only go to its lowest amperage which is 2?
what liquid are you using. is it just water.
Not water. Many people use a solution of wash soda also called soda ash, not to be confused with baking soda. It’s a 1/2 cup soda ash to 5 gallons water. There are other electrolyte solutions as well. Hope that helps.
So I did a dry run in this and a 9v did trigger it,but it would hold in the charging mode when I opened the circuit, now could this be because I wasn't hooked up in electrolyte?
I seen another guy he was inside and disconnect black wirer + to a small circuit board did the same thing just sayin.
What is the connector called that you use to separate the polarities of the 12 Volt Adapter and where did you buy it.
How many amps does the adapter have to be? I have one that is 1.5 amps, should it work? Will a 9V battery work?
I'm using the latest version of this centech harbor freight charger. The circuit board is smaller and different, I tried this trick with a 7.5V DC adapter and it did not work.
BallsonPHACE same here
Anyway, just put it in parallel with any car battery and then you can do electrolysis
7.5 may be too low, may need 9-12v
