How to prevent the misunderstanding of using battery

The first charge: It is necessary to charge for more than 12 hours. Nowadays mobile phones mostly use lithium-ion batteries. Unlike the previous nickel-hydrogen batteries, lithium-ion batteries do not have a memory effect (to be correct, the memory effect is very weak), and there is no activation. For one thing, long-term charging will cause certain damage to the battery. So what is the best time to control the first charging time? This depends on the battery capacity. Generally speaking, it takes 2 to 4 hours. After the mobile phone appears to be charged, it can be charged for another half an hour. Overcharging: It will cause the battery to burst. Lithium-ion batteries generally have safety maintenance circuits and a variety of safety devices to ensure that the battery circuit is actively cut off when overcharging and discharging and short-circuiting; excessive internal pressure of the battery will also trigger the decompression of the exhaust equipment; If the battery temperature is too high, it will trigger the hot melt maintenance equipment to stop the electrochemical reaction of the battery. Therefore, unless there is a quality problem, the battery will not burst due to being plugged in for a long time. However, if the battery is not unplugged after charging or overflowing, the battery will always remain fully charged. Although it will not burst, it will speed up the loss of battery capacity. In addition, there are rumors that answering the phone while the phone is charging will cause an explosion. Experts show that this argument is untenable. If such a risk really exists, the product will set up a procedure that does not connect to the phone while charging. However, it is best to unplug the power before talking. When charging, do not cover anything on the battery or put it on the bed to avoid fire. Almighty charger: It is omnipotent. Many people like to use the all-round charger, thinking that it is cheap and convenient. However, this kind of charger is not made by the original factory, its charging current is not suitable for all battery models, and the charger itself is of low quality The quality has caused many blasting incidents. Other problems ① Put the phone in the sun to warm the phone. Many old models of mobile phones show that the battery power is lower in winter than in other seasons. This is because the chemical reaction activity in the battery is reduced due to the coldness. Therefore, many people like to put the phone in the sun. Put it under the sun, or put it next to the heater. This approach is also wrong. Once the battery is overheated, it can easily cause explosion. ②The battery of the mobile phone can be restored after being frozen in the freezer of the refrigerator for three days. There are rumors on the Internet that the old battery of the mobile phone can be restored after being frozen in the refrigerator for three days. Many netizens have tried it and the results are really effective. In fact, this approach is also undesirable. The humidity in the freezer compartment of the refrigerator is high. Once the mobile phone battery gets damp, it is extremely risky in use. Experts indicate that it is not necessary to store the mobile phone battery for a period of time, and the power will be partially restored when used again. Freezing in the refrigerator will damage the internal structure of the battery. Although it will show a short-term increase in power, it will lose the effect after repeated use. And seriously affect the battery life. . ③The battery cannot be used again when the battery reaches the limit of the number of recharges. Manufacturers generally indicate the limit of the number of use of the battery in the mobile phone manual, while the customer calculates the battery life based on the number of times. In fact, the life of the battery depends on the use, storage, and There are no fixed values u200bu200bfor various factors such as charging. ④Battery cleaning is not emphasized. Among mobile phone users, few people pay attention to the cleaning of the battery. In fact, accidentally wipe the metal contact surface of the battery with an eraser, which can remove the rusty material on the metal surface and help the battery charge. And extend battery life. ⑤Mobile phones u003d game consoles. Some young people like gaming phones, holding a mobile phone to play wherever they go. However, gaming phones generally have higher chip functions and poor heat dissipation. Long-term use will cause the body and battery to overheat. A blast occurred. ⑥ The battery appears to be overcharged, but the mobile phone automatically shuts down after a while. In most cases of this kind of situation, the battery is charging abnormally, and it needs to be charged for eight hours before using it normally. ⑦If the battery is dead, the phone will not be charged after the phone is automatically turned off. This means that the power in the battery is completely used. Also, you need to use the all-around charge for a while and then use the direct charge after the battery is fully charged.
