What should I pay attention to when using mobile phone batteries?

What problems should we pay attention to when using mobile phone batteries? The news of the explosion of the mobile phone battery is broken. It is better to be careful about this product that we carry every day. It is not so safe whether it is placed on the chest or in the pocket of the pants. I have some exchanges with relevant people in the industry, and combined with a little knowledge I have accumulated, talk about things that should be paid attention to, and make a reminder about friends. 1. Use original batteries or batteries from big-name manufacturers as much as possible. Speaking of it, this issue should be criticized by those cottage manufacturers and small manufacturers, but I still want to talk about it. The battery is a dangerous product, and its craftsmanship and protection are required to be higher. This is not like the mobile phone itself, but the quality is not good, and there is no harm. There are several aspects of battery quality assurance. First, the materials used are aluminum alloys or other metals. High-quality materials are expensive. The second is whether there is a good over-voltage protection, a good sensor chip, there are also many particulars in the circuit design. Some low-priced batteries, in order to save costs, use cheap materials, or even no overcharge protection chip at all, the probability of problems is much greater. 2. Be sure to buy a good charger. Nowadays, mobile phone chargers are cheap to 20 yuan, or even 10 yuan. More than 70% of the chargers on the market are substandard. Maybe this ratio is even higher. Substandard chargers have no overcharge protection function. , When the battery is fully charged, it cannot be automatically powered off. Long-term charging will easily cause the battery to overheat and the possibility of battery explosion is even greater. 3. Do not charge repeatedly for a long time. Many salespersons will tell you that a new battery should be sufficient for 12 hours the first three times. In fact, the current lithium battery has a small memory effect. Don't charge it for a long time. If you are a better charger, the battery also has a good protection chip. After the battery is fully charged, it is powered off and will not be charged for a long time. If the charger used is not good, the battery is not good, so charging can easily cause overheating. It bursts or even explodes. 4. Be careful not to put other metal objects in your mobile phone pocket. Everyone can pay attention to it. Many of the metal pieces of the charging ports of our mobile phones are exposed. If these ports are accidentally touched with metal objects, it is easy to cause a short circuit. If the battery is fully charged, this kind of short circuit. A large amount of heat will appear in a short time. If the quality of the battery is not very good, and the sealing material has problems, it will be easier to burst. 5. It's best not to buy a large and easy cell phone battery. The current copycats are often called long-term standby, not to save power, but to make the battery very large. At present, the general mobile phone battery is 1000mAh, and even the largest mobile phone battery is below 1500mAh, but some cottage phones can make the battery 3000mAh or even 4500mAh. Although the standby time is long, this battery stores too much energy. Inappropriate, improper use, short-circuit occurs, this huge energy is released quickly, even if the material is good, it may burst, not to mention the closed material is not good.
