Analysis of the correct maintenance and use of lithium batteries

1. Frequent deep charging and discharging: Lithium batteries have almost no memory. When using lithium batteries or lithium-ion digital products, many friends like to use up the power (protection board protection) and then recharge, and in many people’s eyes , This is also a way to activate the battery. In the use of lithium batteries, we call the state of recharging after running out of power as deep charging and discharging. In fact, deep charge and discharge is a major misunderstanding of many people when using lithium batteries. Scientists have concluded through experiments that the number of deep charge and discharge is directly proportional to the battery life under other environmental conditions. Will cause the battery life to end prematurely. Lithium batteries with a long service life can easily cause battery swelling and other situations, which can cause an explosion. 2. Overcharge and discharge and excessive charging and discharging current: This situation often occurs when the protection board is designed to be unreasonable and charging. We often like to charge for a while after the power of the device is overflowing, so that our device can The resistance time is longer, but what many people don’t know is that long-term overcharge and overdischarge will cause serious damage and damage to the performance of the lithium battery, and the serious will cause extreme conditions such as explosion, so the battery will overflow It’s fine, if you keep plugging in the charger, it will lead to tragedy sooner or later. 3. When charging and discharging, the current of the charger and the general current load of the electrical appliance should be within the specified range. Excessive current load can easily cause the internal short circuit of the battery, which will damage the lithium ion and cause the safety of the circuit. The same applies to the voltage of the rechargeable charger. So when we use the charger, we must also pay attention to see if the charger is qualified. 4. Working environment. Lithium batteries are extremely sensitive to temperature. If they are used below freezing for a long time, they may have a great impact and harm on battery life. Long-term exposure to an overheated environment will greatly reduce the life of the battery. In severe cases, the internal pressure will increase and cause an explosion. Even if there is no explosion, the battery will quickly be scrapped in high heat. I feel that in some cases, it is unfortunate because of the explosion of the pool Most of the disasters were caused by the high temperature of the working environment.
