What’s the replacement wires In case I couldn’t get one

Is it really heats the body

Make your own flux paste. Dissolve rosin in 99% isopropyl alcohol then add petrolatum. Mix well with low heat until homogeneous then add the solder wire as per your method.

But does it also recharge the battery? That is, when the battery is not used but there is only the power supply, does this recharge the battery? Because I have not seen any tp4056...

Batteries go down and even die every year especially during winter and rain. Only valid way to revive them is to use a low amp charger and perform a full charge discharge. Nowadays good chargers are available which try to repair batteries and give them a better charge. I have to revive my batteries every this and that time. They get charged easily and surprisingly don’t actually die as people think. Revival of dead batteries is though time consuming endeavour and need patience. They also need to be fully charged and then discharged fully a few times before putting them on actual use. This happens every year so it’s common. Users as well as merchants both prefer replacing the batteries instead of charging them for restoring. Good luck!!!

Your method is wrong. First of all you never wash an AGM battery, simply because this cannot be done. Then, after filling in the cells with distilled water only, you let the battery to stand for a day and absorb the water fully. If there is need you add more water. After that you put the battery in charging process, but with very low amperage. You need to keep tags on the battery. Note the rythm of the voltage rise. This will be very slow anyway. If you try to charge a heavily sulfated battery with high current, you will very soon see that its temperature is getting high, while the voltage across it is not increasing. This is the common indication of a heavily sulfated battery. All the charging energy is transformed (i.e lost) in heat. So the charging current must be slow. For the battery of this video, the current should be constantly limited to about 150mA. In order to achieve this, you need a bench power supply, not a wall pack. Adjust the voltage to a high level until you see the current rising to the desired level (150mA) and then let it stay there no matter if it is high in level (say 25V or even more, for example). As the battery charges, the voltage will drop and it should stay very near to 12V, if all the cells of the battery are still healthy. If, instead, the voltage stays at about 10V, then one cell of the battery is shorted and the battery has almost no chance to recover. The entire process is inherently slow and it needs time and periodical inspection. Do not expect to recover sulfation, which is a cumulative result of long time use, within a few hours. It needs its own time and therefore a lot of patience on one's part. The point is that it works in many cases, depending on the heath status of each battery to be treated. If there are no internal shorts, in most cases the battery can be saved. Keep on charging, until the voltage reaches 14,7 or 15V. Stop the process, when the charging current drops below 100mA. The battery voltage should then drop slowly and stay to 12,7 volts or thereabout.

@ElectraBoost - Use search engine. Type battery desulfation.

You do not need to add more acid. The Sulfur gets deposited on the Lead Plates. This is called Sulfation. You need to make sure that the cells in the battery are covered with DISTILLED WATER. After that you have two options, one is more dangerous than the other. You either need to use very short pulses of high voltage, for example 100 volts for 5 milliseconds, for a period of several hours to several days depending on how large the battery is and how much sulfation has occurred. Or the following dangerous method. YOU CANNOT USE THE AMP METHOD WITH A SEALED BATTERY, IT WILL EXPLODE! YOU MUST ONLY USE THE AMP METHOD WITH THE FILL CAPS REMOVED SO THE GASES CAN ESCAPE BECAUSE ELECTROLYSIS WILL HAPPEN. You need to use high amps instead of voltage to force the sulfur back into solution, for example a CAR BATTERY (12 volts 200 amp hours), you need to use 14 volts-ish and 50 amps up to 200 amps while monitoring the temperature of the battery and how much gas is being produced. You will destroy a smaller battery than a car battery if you use 200 amps! Use your brain. You must keep the cells below 150 degrees F and make sure the cells are covered with water. Any part of the cell that is not covered in water will not have the sulfur removed because the water is needed to make sulfuric acid and the exposed cell will simply overheat just like any other piece of metal attached to an electrical circuit.

QED!

Water only dilutes the acid more, epic fail

too much water not enough acid. you should charge it with the caps open, and should have added suphuric acid.

You should do a video on the desulfurization charger. I've got one I've just started to use on some AGM batteries I will let you know how it works.

You can get volts back, but not amps.

try i teaspoon epsom salts per cell

Het is goed maar u moet de voeding bron laten zien lhitium 3,7 volt

I think the proper name is cream solder or paste solder rather than solder paste.

There's no point to the 100 mA fuse. The 50k resistor will limit the max current of the whole thing to under 5 mA anyway, so the fuse would never blow, even in a dead short. For better safety, you should put the resistor on the hot line instead of the neutral (it would also be better to use two resistors in series instead of just one, and cover the hot conductor and the resistors in shrink tubing so they're all insulated and you can't accidentally touch them. Reducing the resistor to 4.7k will allow it to charge up faster, but will not increase the maximum amount of voltage or charge it can reach. For that you will need more multiplier stages (for more voltage = longer spark), or larger capacitors (for more charge = brighter / longer-lasting spark). Also note that using a 4.7k also makes the circuit *considerably less safe* as it allows enough current to pass that you can actually cause sustained electrocution if you touch across the lower stage of the multiplier circuit by accident.

Is it safe??? What what about in rain?

Awesome!

Nice video, I think that I would need to know the modules that you used at the end for the power supply, cause in my case Im just starting with the electronics hobby so I dont have any idea how to ask for that in my store hahahahhaha. I'll try to do the same but using the 110V AC that way I can use it as a homemade ringcamera

Ask your questions in the comments

If you put 2 in supercaps series (although the package already has some of the same capacitance in series), it is wise to match the same value of capacitance. Otherwise you end up charging the capacitors with the lowest capacitance negative. Which will shorten their live dramatically. From an endless live to (almost) one-time use. I charge my phone every day (using an USB 12-24 V car adapter)) by charging up supercaps with my electric bike. The caps still have the same capacitance. (ps: I have to peddle on the electric bike to generate power, the motor is used as a generator). This way I keep my phone between 20 and 80% charge for a prolonged life of the (non replaceable) battery.

still don't know how much energy does a supercapacitor store.

Put salt in a cup, get a 24v or higher voltage power supply, put the solder in the positive and some metal in the negative, this will sinterize the solder into nanoballs far smaller than what you can get mechanically, it will let you make the expensive kind of solder paste this way. You're welcome.

same😂

Super!

can i put it 4 dc motor here

Good job bro

reported this video as very danger open high voltage risk careless presentation ...

I feel like it would be better to put flux core solder into a motorized tumbler. I don't see any practical use for solder paste this corse. But maybe I'm wrong.

3 minutes I won't be getting back,,,,

I did not understand anything

probably the car burned down :D

Wondering if any custom PCBs are required for any upcoming projects? If so, would love to sponsor and reach any collab together. (PCBWay zoey)

What kind of wire are you using for the coils?

The heartbeat module used in the video is MAX30102.

Danke!!

Tnx bro for making this vid.

Upgrade ur cutter please

😮

May i have your E-Mail adresse, because i have some questions about this video.

Tnx 4 making this video for us.
