How much do you know about batteries?

Many friends have a habit of charging the mobile phone when it is out of power, but in fact, this habit will seriously affect the health of the battery. If the battery level of the mobile phone is lower than 20% for a long time, the activity of chemical substances in the battery will be reduced Shorten the service life of lithium batteries! ! If you use the shutdown every time, congratulations, your battery life has been greatly shortened by you. So? How to keep the battery active? We can think of the battery as the stomach of the human body. Too hungry and too supportive is unhealthy. In medicine, eating small meals and frequent meals is one of the means to treat stomach problems. For batteries, eating small meals and more meals means charging less frequently, which can keep the battery life longer and keep the battery level between 25% and 80%, which is beneficial to the health of the battery. great help. 03Computer battery Computer is also a daily tool that is difficult to discard for office workers. Compared with desktop computers, more friends will choose laptops, which are convenient and easy to carry. However, if you don't protect the battery properly, you will also encounter the embarrassing situation of looking for sockets everywhere when the battery is out of power on a business trip. The most correct way is to maintain the laptop battery on a daily basis to make the laptop more battery life. It is a wrong way to use the notebook with the power always plugged in. Because the notebook charging cycle is 0%-100%, but the cycle will be blocked if the power is always plugged in, which affects the battery life. After the laptop is fully charged, unplug the power supply and maintain a 50%-80% power level. Use a black background to save power. Choose a beautiful picture as the background picture of your laptop. It looks good and eye-catching, but this choice is very power hungry. Because the OLED of the notebook screen allows each pixel to emit light independently, the more colors the picture, the more power it consumes. On the contrary, if you choose a black background, the screen pixels are turned off, which saves more power. Hibernation≠sleep In notebook computers, there are two modes of hibernation and sleep. Some users may think that they are the same mode. This is wrong. Sleep mode will make the laptop still use its memory and run out of power when it is turned off; while hibernation The model is not like this. Mobile phones and computers have something in common. Frequent cleaning up of mobile phone and computer memory can not only make the system run faster, but also help the device save power. The slow operation of the device will affect the life of the battery, so it is necessary to develop regular cleaning of computer garbage. 04 A discarded mobile phone battery can pollute 60,000 liters of drinking water, which is equivalent to the daily drinking water of 20,000 people, and its pollution intensity is 100 times that of ordinary dry batteries. Electrolyte solutions such as waste acid and waste alkali may pollute the land, acidify and salinize the land, and cause long-term damage to the ecological environment. Such soil and water enter the human body through agricultural products, causing serious consequences such as visceral damage, bone deformation and bone pain, and liver and kidney damage. So untreated used batteries are a time bomb buried around people. We must put waste mobile phones and laptop batteries into hazardous trash bins, and do not throw them away.
