A patina appears on the copper sheet of the mobile phone battery First aid!!

It's a copper problem. This copper is very important for the battery, it is a part of the battery protection board, the battery protection board is to ensure the safe use of the battery, the protection plate is not good, it is easy to cause the battery. You still ask the merchant to change a copper sheet, that is, to change a protective board.

The protective board is also not expensive, that is, 1 to 2 yuan. But you said that the current battery has a short period of time, which means that the battery must be damaged and the life span is shortened. As a newly sold battery, you can also ask the merchant to replace a battery.

Generally, the batteries of the brand are replaced every six months, except for garbage batteries.

It is evident that the copper sheet is oxidized, resulting in copper oxide.

It's green, this patina.

will affect electrical conductivity and must be treated:

Use a blade to gently scrape off the patina.

On the patina, use a welding torch to spot a drop of tin, and then flatten, and deal with it quickly to prevent the battery case soup from melting away.

If there is no condition, you can only send the mobile phone to the repair point and ask the master to deal with it.

That's because of the aging of the battery, it is recommended to put the battery in the refrigerator to freeze for a while, which can prolong the life.

Patina is alkaline copper carbonate, you can consider using a cotton swab to dip a little weak acid to wipe it, but don't get too much, otherwise the battery will be scrapped if the battery enters the water, short-circuit and leakage. Just to give you an idea, because no one has tried this method, so don't try it lightly. Huh

This problem should not occur when you buy a new one, this situation is because the chemical elements inside the battery begin to liquefy, which generally takes a long time for the battery to appear, you can ask the seller to change the battery, or buy another one, there is no other way.

Where to buy the battery, find that store to ......Just bought this problem ......It's obviously a rotten ......And ......The patina may appear due to contact with water or high humidity in ......the environmentDo you often keep your phone in a damp place?

Hello, the newly bought one can be exchanged.

If you are not short of money, don't use it, because in this case, the battery is very easy to explode, and the gains outweigh the losses.

You can't spend a lot of money to buy an electric Huai pool, and Pisen's batteries are all commercial battery chips, which are very good to use potato dust.

Just wipe it with sandpaper or use something to scrape the copper sheet, don't waste money and protect the environment.

If it's a good phone, maybe it's not so fast to break, if your garbage phone is broken, it's okay, wipe it with pants and dry it to dry. Stove. Agree and get extra points...

You still change the battery handle to avoid danger.

It is copper sulphate, which is green in color, while copper oxide is black. The appearance of green copper sulfate indicates that your battery pile head is loose, and the sulfuric acid is seeped out of the pile head, and the sulfuric acid and the copper clamp of the battery pile head have a chemical reaction.

The green thing is patina, which is formed after copper is placed in a humid environment for a long time, and its formation will affect the conductivity of copper, so that it will decrease, the resistance will increase, and the heat will be generated by a large current, and danger will occur.

Therefore, it should be disposed of in time, rubbed off with an abrasive cloth or filed with a file, and moisture-proof measures should be taken!!

It's copper oxide, and the battery has been exposed to the air for too long, so it should be worn off.

Confirm which contact (copper sheet) is broken.

The three contacts of the mobile phone battery are the positive and negative terminals, and the other is the temperature sensing voltage output.

The mobile phone is a lithium battery, if the contact of the positive and negative poles is broken, there is no way to charge and discharge, and the lithium battery has certain safety hazards, so a temperature sensor is added inside the battery to monitor the temperature inside the battery cell at any time, and when the temperature of the battery is abnormal, a specific voltage will be generated on the battery pole. Usually, it is easy to cause the battery temperature to be too high when charging, at this time the charging will automatically cut off, which is to rely on this pole, when the mobile phone is working, when the mobile phone detects this voltage, it will automatically shut down immediately to protect the mobile phone and the battery. This pole is useful.

Nokia mobile phone is low level start, the middle one and the left is the positive pole, the right is the negative pole, and it can also be turned on to indicate that the click is not completely broken, there are many reasons for the crash, it is recommended that you go to the local Nokia after-sales processing center to repair. The address can be found on the official website.

It means that you are going to buy an N97, and then you can cut off the battery, throw away the rest, and put it on your 95.

Bend the end of the staple and squeeze it into the broken hole.

Electrode It's good to buy a new battery

Like this, you might as well change it! If you really don't want to change it, you just use a little toothpaste to wipe it with a cotton swab, and it will be fine in a while!

The more you wipe it, the easier it is to rust, you don't have to wipe it, and you have to replace the battery after a certain number of years.

Change the battery, you look like you're damp.

Touch a little bit of our usual caustic soda water, and then wipe it dry after a while.

Take it to the repair shop, ask the master to help you weld it, if it is broken, you have to find a replacement, generally 20 yuan Follow-up: It is the three copper sheets on the mobile phone. Can it be repaired?

How much does it cost if it breaks? Answer: I know, it's those battery contacts, I often help others change, are 20 (some contacts are particularly difficult to find, it's a big deal to collect 30), acquaintances 10 yuan, 15 are receiving.

Those who don't understand, don't talk nonsense, 100 have said it, do you want to harm others to be slaughtered. Rest assured to take it to the repair shop to repair it, about 20 yuan, if you don't have one, just go to two more, that thing is easy to find. There is also a few dollars that say that the thing is only a few dollars to get the goods, but the repair shop has to pay rent, eat, can repair a few machines a day, how much money can be made, everyone will count Ask:

Uh-huh. Thanks.

The landlord is very attentive, hehe. However, it is only a problem of electric shock, there is no need to worry, as long as the contact is picked out, there is no false leaning on the battery. It won't crash.

Don't worry about leakage or anything. You can use it with confidence. If the landlord is still not at ease, if you are free, you can go to the maintenance center to test the customer service for free.

The lithium battery comes with a protection circuit, and the landlord can rest assured that the problem is overcharged.

Just pick the contact, there will be no leakage or anything.

First of all, you need to make sure that there are any other places besides the reed that also have this phenomenon (such as the edge of the label), and then do you smell any pungent smell? If there is, then it is possible that the battery is leaking, please do not use the battery again. If the above problems can be ruled out, either you have come into contact with the sweat eggplant filial piety liquid on your hands when you store it, and then there is water on the reed sheet, the copper sheet and the oxygen in the air are oxidized, but it is generally displayed as green, you wipe it with an eraser or wipe it with alcohol, and the battery can be used normally, thank you!

Rust is formed, and the copper sheet and the oxygen in the air are oxidized. Clean it up and use it normally.

It's okay, just wipe it with alcohol.

That's that serious. The battery will not be short-circuited until the positive and negative poles touch together, do you see that they are possible to connect together?
