All this was initiated by Ji Dongqing. Although he was a little passive, Liu Fuzhi still completed it brilliantly.

People from the local organizational department said, "This college student is really responsible!" The county had already prepared a promotional video and was waiting for Liu Fuzhi to graduate.

"Work hard. At least you won't have to worry about finding a wife. There are little nurses everywhere. They're pretty and good at taking care of people. They're close to the water!"

"Go, go, go, I think, my family has stipulated that you can't touch many things within a few years, otherwise you will die. How are you preparing for the postgraduate entrance examination? If not, you will come to our county in the future. We have connections there.

There are still many mines, so I can just let you have your share of car repairs!"

What Liu Fuzhi says now comes from his heart. People's hearts are in the face of big issues. When Liu Fuzhi went home, he told his experience to the old man at home, and the old man said: This person is trustworthy.

"I'll wait and see. I still want to stay in the big city for a longer time. I feel a little unwilling to do so. Although it's not necessarily right, I'll wait for two years. If it doesn't work, I'll find you!"

"I haven't mentioned it yet. If I didn't have family connections, I would have tried my hand at it just like you. After all, I'd rather not try my luck after going to college!"

After they finished their work, Ji Dongqing returned to the repair shop.

I checked the work as usual and made arrangements for the unreasonable parts. Xiao Hu is now in a good shape. After working intensively in the past few days, Xiao Hu has grown very fast.

When San Pao saw Ji Dongqing, he was like a mouse seeing a cat. He was much more disciplined than before.

“Jianping!“

"Brother Dongqing!"

Hearing Ji Dongqing's call, San Pao trembled and hurried over.

"Wear this hat from now on!"

Ji Dongqing gave Sanpao a white helmet in his hand, which Ji Dongqing bought at a huge price.

"okay!"

"Do you know what it means? In the north and even in every place in our country, wearing white on your head proves that there is a funeral in the family! Do you understand that you are wearing a white hat to prevent funerals from happening in our family? Security officer!"

"Eh……"

Although Sanpao was unwilling, Ji Dongqing was right. Before turning around, Ji Dongqing directly stuffed an ID card into Sanpao.

"Damn it, security officer, recognized by the country, that's it Brother Dongqing, next time if anything happens I'll fill it in myself!"

"Go to work and don't make anyone annoying!"

Originally, Sanpao was just wandering around the factory, but now that he has the certificate of safety officer, he is officially on duty, which is equivalent to becoming a mother-in-law after being a daughter-in-law for many years. Ji Dongqing ignored him.

Invite Xiao Hu and Xiao Gao to come over and bring over the lead-acid batteries that were recently replaced, especially the big batteries for trucks.

"I'm looking for Valta's mainly, and then the sails. I don't want batteries from other small families!"

After putting on protective gear, Ji Dongqing and his two young apprentices began to work.

"Pour out the electrolyte inside first, be careful!"

Ji Dongqing marked several types of batteries and made a simple tool. Xiao Gao was responsible for removing the cover, and Xiao Hu was responsible for pouring the electrolyte.

These scrapped automobile lead-acid batteries basically have the anode lead plates inside burned out, so it is not difficult to renovate them.

These scrapped electrolytes contained heavy amounts of free lead. Ji Dongqing asked Xiao Gao to get a large plastic bucket and pour all the electrolytes into it.

"You must wear rubber gloves. There is sulfuric acid on this lead plate. Use the hot water here to wash it..."

After separating the lead plates inside the anode and removing the asbestos plates between each piece, Ji Dongqing began to teach the two of them.

It has not been very profitable to renovate car batteries in recent years, especially for small workshops like this, where it is difficult to dispose of used electrolyte.

The procedures at Huang De's place were relatively complete. Someone came to pick up the waste engine oil regularly. Ji Dongqing dumped the electrolyte directly to him. He had the documents to dispose of the waste, so he dared to do this.

All the anode lead plates were damaged to varying degrees, and there were actually some on the cathode side as well. Ji Dongqing just picked up some of the more damaged ones and threw the less damaged ones directly inside.

I'm just using it as a backup power supply, not for long-term use, so I don't need to worry too much.

"Cut these!"

Pointing to the anode lead plate connecting block, Ji Dongqing asked Xiao Hu to do it himself. Although he smoked, he still kept an eye on it, worried that something might go wrong.

All the lead plates fell apart, and Ji Dongqing asked both of them to put on gas masks.

The crucible was brought over and the acetylene was plugged in. Xiao Hu cut all the lead plates into pieces and threw them inside.

Ji Dongqing asked Xiao Hu to get the mold again. A few days ago, Ji Dongqing made a simple mold using internal wire cutting, and now it is basically completed.

"puff!"

The flame was lit, the lid was closed, Ji Dongqing looked at his watch, and when he was done, he took out the crucible furnace and removed the dregs on it.

"Pour it in!"

Pointing to this row of molds, Ji Dongqing whispered an order, and Xiao Gao and Xiao Hu began to work.

After one row of pouring is completed, the mold is taken out, and the lead blocks continue to be melted here, and all the work is done in an orderly manner.

The work of trimming the flash on the surface of the lead plate was left to Xiao Hu. Now that the flash was no longer adhered to by the sulfuric acid electrolyte, Ji Dongqing let him start the work with confidence and boldness.

I trimmed the asbestos boards myself and soon the first anode lead plate was ready.

"Bang bang!"

"It must be stronger, like this!"

All the lead plates were tightly connected, put on rubber bands, and Ji Dongqing stuffed the neatly cut out ends into the mold.

He waved a small crucible filled with lead solution and poured it in. After a while, the anode terminal exactly the same as before was completed.

The next step was assembly and welding, which Ji Dongqing and Xiao Hu completed.

All the terminals were connected in series. Ji Dongqing closed the cover. The remaining welding work was what Ji Dongqing was good at.

The battery module with a clean surface is not difficult to weld. The plastic welding rods are quickly welded together under the wash of the hot melt gun. Ji Dongqing cannot afford to miss any point.

"Add acid!"

High-concentration sulfuric acid slowly flowed into the plastic funnel, and every space was filled. Ji Dongqing placed the cylindrical mold and completed the battery connection terminals with a little bit of solution.

"Are you ready?"

"Well, let's make the lead plate first. It doesn't matter if you take it slow. Just be careful and you won't make a big mistake!"

Ji Dongqing sat aside and stared at the two of them closely. The rest was repetitive and monotonous. Only the last job was for Ji Dongqing to weld by himself.

Strictly speaking, this kind of renovation is not allowed, but few people in China really care about this.

The north is stricter, while the large, medium and small workshops in the south renovate batteries in large numbers. There is one place that Ji Dongqing forgot about. It seems that it is the largest car battery refurbishment base in China.

You can use any kind of battery you want, as long as you want it, and the price is cheap.

Because the waste electrolyte contains heavy metal lead, once it leaks into the soil, it will pollute the environment and pose a threat to the safety of surrounding drinking water.

Heavy metal ions are particularly harmful to the human body, especially lead ions.

"This is good, Dongqing, do it well, if you do this our business will grow!"
