You can use a thin piece of wire to instantly short the positive and negative terminals of the battery. Remember, if you see sparks, unplug it immediately. This activates the battery and increases its capacity.
This method is very effective when the battery is discharged and an emergency is necessary. Generally, the phone cannot be turned on if the battery is discharged. Using this method, the phone can continue talking for almost 10 minutes.
But do not use this method frequently, because this situation is similar to cardiac activation.
What should I do if the lithium battery cannot be charged? Let's take a look below.
1. When using lithium batteries, it should be noted that the battery will enter a sleep state after being left for a period of time.
2. Self-discharge will cause the battery to discharge. At this point, thecapacity is lower than normal value, which will make the battery too weak and unable to charge.
3. However, lithium batteries are easy to activate. The battery can be activated and restored to normal capacity after 3-5 normal charge and discharge cycles.
4. Due to the characteristics of lithium batteries themselves, lithium batteries have almost no memory effect, so the new lithium batteries in users' mobile phones do not require special methods and equipment during the activation process.
5. This is not only true in theory, but from my own practice, the "natural activation" method of loading using standard methods from the beginning is best.
What is the reason why lithium batteries cannot be charged?
There are many types of lithium batteries, includingincluding batteries made of round cells like 18650 and lithium batteries made of polymers. divided into two main categories, lithium metal batteries and lithium ion batteries. Charging methods basically include constant current charging, constant voltage charging, pulse charging, etc. Different charging methods are used at different stages if charging does not arrive. , There are several situations:
1. The lithium battery is in an over-discharge state
That is, the lithium battery is discharged very weakly, is in a deep discharge. state, and the energy is almost exhausted. As low as the cut-off voltage of the lithium battery, activation methods can be used at this time, but this is not necessarily effective;
2. a problem with the charger or charging line
First, you need to check the charging. If there is a problem with the device, the method is very simple. You can directly measure the output voltage or connect a load. with the corresponding voltage and observe. If there is a problem with the circuit, then you need to put in some effort. After all, it involves circuit hardware and other issues. If necessary, just open the scan.
3. The lithium battery will fail after prolonged use
The possibility of this happening is relatively small, but it cannot be ruled out. You need to know your own battery. How long does it take to replace the battery?
4. There is a problem with the battery charging IC or BMS system
Due to cell imbalance and other reasons, the battery management system has problems, leading to the integrated management circuit to incorrectly evaluate and not detect the voltage or current.
The batteriess of Cameronsino mobile phones, fourteen years of attention to battery manufacturing technology, are safe and stable, without the risk of explosion, continuedIt has strong navigation ability, lasting power, charging conversion rate high, does not heat up, long life and is durable. This is a battery brand worth choosing.
