How to buy laptop batteries?

Notebook batteries with formal processing technology are generally difficult to cause problems, but the batteries that pass through the hands of second-hand notebook manufacturers in the computer city can be different. Perhaps many friends think that the notebook battery module is composed of 4 to 8 batteries about the size of the AA battery, but what is more important is a charging protection circuit that is a few centimeters square. There is a related experience of battery use that: due to long-term overcharge of the battery, the lithium battery may discharge a large amount of current instantly under special temperature, humidity, and poor contact conditions or environments, causing spontaneous combustion or explosion. The function of that small-sized charging protection circuit is to guard against the occurrence of the above-mentioned situation. The battery is composed of batteries and a control circuit. We can often see batches of refurbished batteries in the second-hand notebook market in the Computer City, but it should be said that although these batteries can restore a certain endurance, few of them are charged. Of the protection circuit. In other words, when your laptop is going to be used for more than ten hours a day, the battery overcharge will be inevitable, and the probability of explosion or fire will increase greatly. A group of battery cells may have friends who retort that it will be fine if I remove the battery while using the laptop. Regardless of the identity of the laptop that has lost the battery, the battery that is removed will continue to be discharged, especially after it is fully discharged (half a month to a month), your battery will be one step closer to being scrapped. . In addition, for batteries that have been brutally refurbished, there are still defects or internal short-circuits, and this is one of the reasons for the spontaneous combustion and explosion of the battery. In fact, many laptop users have experienced re-purchase after battery failure. Although the original battery works well, it is somewhat expensive. My proposal is that if you really want a battery with effective battery life, then whether the replacement battery can be used safely for your use becomes the first consideration. However, while passively accepting the original high-priced batteries, we also hope that third-party battery manufacturers with real technical strength can emerge as soon as possible. By then, the era of high-priced notebook batteries is believed to be eliminated. According to inaccurate third-party sources, the mobile phone battery that exploded and caused serious injuries came from some copycat manufacturers, and this is somewhat similar to refurbished or self-made laptop batteries. This is just like what I said at the beginning of this article. The technology of lithium batteries is very mature, but there are still certain rules for its use!
