It is actually not that easy to discharge the battery. This is mainly related to the type of battery. For example, it is easier to discharge the battery if it is dry. Even if it is short circuit at most, it will burn or explode on a small scale, and there will be no big problem. ☆→, but some batteries are not so safe.

There are four batteries we have to deal with, among which the lead-acid battery has the largest storage capacity, but it is the safest, because just by letting the acid inside be removed, the remaining three batteries will be a little troublesome.

After our careful inspection, these three batteries seemed to be a hybrid battery, and they were quite advanced. This battery looked like a whole, but in fact it looked like a package. It was actually divided into three parts and a small number of lines inside the battery.

These three parts are one circuit board and two batteries. Yes, they are two batteries. The outside looks like a whole battery actually has two completely different batteries inside, which are connected to a circuit board through wires. The current output from the battery to the outside is also derived from the circuit board rather than directly from the battery.

This packaging mode is generally used only for rechargeable batteries, but generally there will be no situation where two different types of batteries are sealed. This is obviously modified into this structure because of special needs.

Among the two parts sealed in the battery, the larger part located at the bottom is not a big problem. It is just a relatively conventional lithium-ion battery with good power storage and safe discharge. The problem lies in the battery close to the circuit board on it.

This battery, the size of a one-yuan coin stacked together, turned out to be a hydrogen metal battery. The hydrogen metal battery is as famous as its super large capacity because of its unstable characteristics.

Basically, in our understanding, hydrogen metal battery can be considered a battery or a bomb. It would be fine if this thing is out of power. If there is electricity, once the discharge speed is too fast, it will cause the power protection to become faster and faster. In the end, it will completely lose control and explode, and its explosion power is mainly related to its own energy storage. The power of a fully charged hydrogen metal battery is about 8 to 9 times that of the same volume of TNT. Its power is slightly better than a nuclear weapon. If you just get a few kilograms and throw it out, people who don’t know will think it is a small nuclear weapon explosion. From this, you can imagine how unsafe this thing is.

Of course, instability is unstable. In some cases, this thing is actually quite useful, and the self-discharge acceleration characteristics of hydrogen metal can be used to fight against low temperatures, which means that if there is a suitable environment, it is easy to suppress explosions. For example, some civil power stations use hydrogen metal batteries to dump power for a short period of time, and in order to suppress explosions, a special liquid nitrogen cooling tank will be prepared to soak the battery directly in liquid nitrogen. At this temperature, hydrogen metal batteries will absolutely not explode directly. Even if they want to explode, they must first evaporate the surrounding liquid nitrogen.

However, it is rare to use hydrogen metal batteries on mobile devices. After all, if a mobile device is not done well, it will fall and other situations. It will explode if you accidentally explode. I don’t know what such a dangerous thing was used for before.

Anyway, what we have to do now is to remove these three hydrogen metal batteries and the lead-acid battery below, and not to lose pressure on the outside oil seal.

"Yefrit, I'm leaving this to you." I said, pointing to the lead-acid battery.

Everett quickly approached, then lay on the ground, then moved his arms to the position where I pointed it out, spreading the multi-functional auxiliary arms at the front of the two robotic arms, and then took out two drill bits from the tool box on his carry-on. This type of drill bit is different from a normal drill bit, that is, it is hollow. There is a hole in the middle like the needle of the syringe, of course, the thickness is not the same as the syringe. This thing is much thicker than the syringe, with a diameter of more than three millimeters.

Insert the drill bit into a small clip at the tip of the finger, then YiFreit put his finger to the position of the battery, and then the drill bit suddenly began to rotate rapidly, and YiFreit's fingers began to move forward slowly and steadily. The most important thing in this process is to be steady. YiFreit's fingers cannot move at all. In this way, the hole drilled out can maintain a perfect fit with the drill bit, so that the oil inside will not flow out when drilling through the outer shell, and naturally there will be no pressure relief.

If it was a human to accomplish this, it would probably be difficult to do, because no matter how stable the human hand was, it would have slight tremors. However, Effrete's body was purely mechanical, and it was as stable as an electric machine tool. As the fingers slowly advanced, the drill bit quickly passed through the pipe shell and then entered the oil seal. However, the drill bit did not stop working, but continued to move forward and quickly touched the inner lead-acid battery shell. The plastic lead-acid battery shell was also penetrated quickly, and the drill bit controlled by Effrete quickly entered the interior of the lead-acid battery.

After confirming that the drill bit had entered the acid liquid, Effrete immediately pinched the drill bit with another hand to stabilize it, then loosened the clip at the tip of the finger with the drill bit, and then used the small clip at the tip of the finger to reduce the aperture and clamp a small metallic feeling inserted in the hole in the middle of the drill bit. Effrete's finger began to rotate in the opposite direction and quickly retreated. A thin metal rod with thread was quickly pulled out, and almost the moment the thing was pulled out, a light yellow acid flowed out immediately, but there was very little flowing acid, and it was obvious that it could not shine the acid in the battery pack.

Of course, we know that it is impossible to release a lot of acid by just one hole, because the battery itself is sealed. If you open a hole, it will form a pressure balance and the acid inside will not flow out by itself. But we have to wait a little while, because once the lead-acid battery emits the current first, the three batteries there will directly detonate the bomb, so we need to discharge them together and ensure that the battery capacity difference is not large, so that the bomb will not be detonated in advance because a certain battery suddenly loses power.

After Yifrit got a hole, he immediately grabbed the drill bit with the auxiliary robot arm, and then used his free arm to start slashing his eyes again. However, this time he did not rush to open the passage, but he just drilled the hole first without pulling out the metal seal in the middle.

After Everett got it done, we started to solve the three more troublesome batteries.

Although this thing is quite troublesome, it is not impossible to find a way. The method we used is actually similar to before. First, hand over the drill bit that Everett made to others to stabilize. Then let Everett come to open holes for these three batteries, but cannot directly open holes in the battery itself. Instead, the two drill bits are used as conductive electrodes to contact the metal contacts, and then start to let the battery quickly release some. During this process, frost and snow also need to cool the oil inside the oil seal next to it, because the battery discharge will heat up, and the hydrogen battery cannot heat up too high. Otherwise, it will explode. However, the bomb has a countdown, so we cannot discharge slowly and can only speed up the discharge. This makes the temperature difficult to control and must be cooled externally.

Fortunately, Frost and Xue have a good temperature control ability. Soon we completed the electrode docking of three special batteries, and then took charge of one battery and pinched two drill bits with both hands. Using our own electromagnetic control ability to control the battery to discharge at the verified speed.

After so much trouble, the numbers on the counter have become only more than five minutes left, but after the previous preparations have been completed, the rest is simple. After more than three minutes, we finally let most of the batteries light up. Although the countdown on the monitor is only more than one minute, it is obvious that the numbers on the monitor have become very dim. This is the result of the battery voltage drop. It is estimated that the bomb battery will be completely out of power in more than ten seconds.

The facts are as accurate as we calculated. After more than ten seconds, the numbers on the bomb suddenly turned completely black, and then we heard that some electrical components inside the bomb seemed to have moved a little. But in the end, we could only hear a clicking sound and there was no trace. This sound was actually because a battery was out of power first, causing the control system in the line to think that the line was cut off, so it began to detonate the bomb. However, because the remaining batteries were out of power, the power gathered by the circuit could not activate the igniter at all. As a result, the relay was just trying to supply power there, but the result was that there was no power supply at all. After a few jumps, the last bit of electricity from the remaining batteries was finally evaporated, and the entire bomb completely failed.

"Ok, this thing is fine."

"Are you here to help me if you have done it?" Jingjing, who is responsible for forming the shield, shouted: "We can't handle it anymore!"

"Just come, come, wait." As soon as I saw the situation around me, I found that there were people everywhere here. I quickly gathered together to reduce the area of ​​the attack. Then I completely dismantled the bomb and took out the core representing the nuclear bomb. I ignored the other parts and started to move towards the stairs not far away.

The people around were shooting at us, but they always felt that they could not penetrate our shields. But now they saw us moving and found that there seemed to be something wrong with the previous battle.
