How to protect the lithium battery during travel?

Don't put electronic equipment in the backpack. When traveling, we usually put laptops or other portable devices in the backpack. But putting electronic equipment in a closed, unventilated space can easily cause the body to overheat and damage the battery. Even if the device is turned off, the heat emitted by the battery will be trapped in the backpack and cannot be discharged, causing thermal runaway and leading to dangerous situations. Prior to this, some manufacturers had recalled the lithium batteries of their own products because of the risk of fire or explosion due to overheating. If you plan to put an electronic device in a closed backpack, you must ensure that its battery is cool, even when it is turned off. In addition, you can also check your backpack to prevent the battery from overheating due to body heat or sunlight. Preventing charging in an unsafe environment Charging electronic devices is a hassle during travel. In the survey, many participants said that they had charged equipment in gas stations, shopping malls, restaurants and even public toilets. As mentioned at the beginning of the article, charging electronic devices in these unconventional environments may cause various unexpected problems. While traveling, you should prepare extra batteries and store them properly to deal with the situation where the device is dead. If your device cannot replace the battery, a mobile power bank is also a convenient choice, especially when there is nowhere to charge it. Don’t listen to the so-called battery maintenance method. Don’t charge it overnight. Make sure to fully charge it before using it. Once in a while, use up the battery completely. We always see these so-called best charging methods in our lives, but have you ever questioned them? Accuracy? The fact is that most of these suggestions are wrong, at least with regard to today's lithium batteries. For example, completely depleting the battery will actually shorten the life of the battery. However, according to the survey, about 33% of users will wait until the remaining power is below 10% before charging. When using electronic equipment, you should try to keep the remaining power between 40-80%, and prevent frequent and complete discharge. In addition, keeping the device charged (overnight charging) is not necessarily a bad thing, because most devices will automatically stop charging after being fully charged. Finally, you should ensure that the device is in a cool environment when charging. If the battery generates excessive heat, stop charging immediately. No need to shut down and charge. On the issue of whether to shut down and charge, there are currently two important points of view: one group believes that shutting down and charging can prevent the loss of equipment parts, and the charging speed will also speed up; while the other group believes that switching off the machine is more likely to wear parts, and Charging faster when turned on. In fact, the switch machine will not have much influence on the components of modern electronic equipment. However, for devices that use lithium batteries, charging in the off state allows the device to reach a low saturation current when it is fully charged, thereby preventing the battery from sustained stress. However, in the power-on state, the current will bypass the battery and directly power the device after most devices are fully charged. All in all, when to shut down and whether to shut down frequently is not important for electronic devices.
