How to fix the lithium battery? The lithium battery is not like a Nickel-chromium battery, which can be followed. For lithium battery discharge, a minimum will be set, and the battery is overlapping is irreversible, that is, our battery will not rush in, this is this. So how to fix the lithium battery? Xiaobian for everyone.

What is over-discharge, what is the impact on lithium battery performance? After the lithium battery is put on, the voltage reaches a certain value, the discharge will cause over-discharge, usually determined according to the discharge current to determine the discharge cutout voltage. 0.2c-2C discharge typically set 1.

0V / branch, 3C or more, set to 0.8V / support, battery excess may bring catastrophic consequences to lithium batteries, especially large currents, Or repeated overlapping the battery effect is greater. In general, the over-discharge will increase the pressure of the lithium battery, and the positive and negative active substance can be reversed.

Even if the charging can only be partially recovered, the capacity will also be significantly attenuated. If you use different capacity or new old batteries, there is a possibility of leakage, zero voltage and other phenomena. This is due to the charging process, the capacity difference causes some batteries to be charged, and some lithium battery is not fully charged, and the battery has a high capacity of high capacity, and the capacity is low.

Such a vicious circle, lithium battery is damaged while leakage or low voltage. How to fix the lithium battery? There are two situations of the lithium battery, one is that the single-chip voltage is zero, one is that the voltage dropped to the charger can be detected. After the single-chip battery decreases to zero, the lithium battery is completely broken, only if all the cells are around 3V, can save back.

At this time, everyone needs to prepare a piece and plate. This battery, after connecting the charger, no voltage is detected. Explain that this battery is over.

In order to save this battery, we need to prepare a normal battery. The voltage of this lithium battery is normally displayed, and the over-the battery is saved. First insert the two batteries onto the plate, connect the charger, adjust the charging current to 0.

3A. Note, you want to bring over the battery, you must charge a small current. When the battery is full, the charger will prompt, remember to pull the lithium battery! Lithium battery charging is generally adopted by "constant current-constant pressure", that is, the start time is a standard current for a while, when the battery voltage reaches the charging deadline, use constant voltage charging.

Therefore, it can be charged with a DC power supply for a period of time. When it arrives until the cutoff voltage is used to charge the original charger, although this method is time, it is not possible, after all, the battery has affected the performance of the battery, but There are also phenomena that have been activated for a few years of lithium batteries. How to fix a cell phone lithium battery? 1.

Gently wipe the metal contacts on lithium batteries and metal contacts on the phone on the phone using clean eraser or other materials to help charging status and power. 2, will use the old mobile phone lithium battery with automatic shutdown to cover it firmly, and we will pay tried to pay for the post when the package is wrapped, ensuring that the battery is in a vacuum. Then, the three-layer newspaper is added outside the plastic wrap, so that the lithium battery is completely sealed.

Add the refrigerator freezer, after 48 hours, remove the battery, remove the six-layer paper film outside the package, and the lithium battery does not cause surface expansion or deformation due to freezing. After a while, then charge. 3, let the lithium battery close to the scrapped completely discharge, then recharge the activation battery.

The specific method is to discharge the phone, which is to achieve a deeper and reproduction by depleting internal energy, which requires some unconventional methods. How to properly keep lithium batteries? 1 Due to the self-discharge phenomenon of lithium batteries, if the battery is not used, the battery voltage cannot be lower than its cutoff voltage, preferably 3.8 to 4.

0V; 2 suggest that the lithium battery is charged for half a year, it is battery Keep it above the cutoff voltage or more; 3 battery storage ambient temperature and humidity should be appropriate, to operate according to the specification;. The above is a method of repairing the lithium battery and the correct lithium battery. After years of development of lithium batteries, there is already a brand in lithium battery maintenance technology.
