The lithium iron phosphate battery cannot be used when it is bulged. The bulging battery will affect its use and cannot be placed in mobile phone or digital camera. Additionally, the presence of gas between the battery plates will also affect the battery. battery charge and discharge capacity. After deflation, it can be restored to its original size and used normally.
Choose the top of the lithium battery close to the bottom edge of the sealing cover (be careful not to drill holes at the bottom of the battery, there is no space there) , and avoid drilling holes for the electrodes. If the two electrodes are on both sides, you need to drill a hole in the middle. Now they are all aluminum shells. You can drill them by hand with a very fine instrument screwdriver. After drilling, be sure to go deep to avoid any danger. to touch the plate'electrode.
If you're lucky, you'll hear the sound of gas escaping after being penetrated. If you're unlucky, there will be no sound at all. Such a battery can no longer be used and must be replaced. . After pricking the eye, you can squeeze the bulging area with your hands appropriately to help the gas between the plates escape. Finally, seal it with tape to prevent air from entering. You can also use 705 silicone sealant.
You can see that there is a placeholder on the front of the lid. Note that if the battery is attached in the wrong position, there may be a partial short circuit, ignition and heat. This position is not suitable for attracting attention. The battery itself is damaged (the battery mentioned here is the cell itself). The interior of the cell is a vacuum structure. Once the exterior is damaged, the battery is not far from beingbe damaged.
Most people know that the battery is overcharged. The cause of overcharging is a bad charger. The cell voltage will increase if it exceeds 4.25V. The cell with good performance can be discharged for a while. the voltage drops, there will be no problem. In severe cases, he may not be able to recover. Even if it is flattened by an external force, it will be useless (and it is generally difficult to flatten by an external force. It is). due to the vacuum we just mentioned, or it is more accurate to say it is completely sealed.) means the battery is over discharged. The standard for over-discharging is that the cell voltage is below 2.7V. The cells will bulge once the voltage is below 2V. If it is below 1V, they will essentially be discharged. scum.

1 Place the electronic scale with its back. face down, expose the battery box cover and snap the plastic baffle into the cavity.
2. After exposing the battery inside, pay attention to the small iron buckle on the side of the battery and push it in the opposite direction of the battery.
3. Without the pressure of the iron buckle, the battery will fall.
4. Take a new battery and place it in the battery box, being careful to squeeze it under the iron buckle.
5. Install the plastic battery baffle and you will hear a slight “pop”.
6. Turn the electronic scale upwards again. A number appears on the screen to indicate that the battery has been successfully replaced.
