Do you know the general correct use of lithium batteries?

1. The correct charging method of lithium battery: The safe working voltage range of lithium battery is 2.5~4.2V, lower or higher than this voltage range, the lithium ions in the battery become very unstable, and even cause accidents. To ensure that the battery is in a safe range, a dedicated charger is required. These chargers will automatically adjust the charging method according to the current state of the battery. 2. To prevent over-discharge: Lithium batteries have no memory effect. They can be charged as you use them. Don't wait until the battery is completely discharged. Try not to use it when the battery is below 20%, especially when it is below 5%. 3. The lithium battery should be prevented from overcharging: it is best not to continue charging the lithium battery when it is fully charged. Although most mobile phones now have overcharge protection, there may be situations where the battery is damaged or there is no overcharge protection, then continue charging It can cause the battery to overheat or even explode. 4. Lithium battery activation: Before the charger starts charging, it will supply the battery with a small current, and at the same time detect the battery voltage change, and gradually increase the current until the set value. This process can be regarded as an activation or test charge. V. Lithium battery storage conditions: The most critical storage conditions for lithium batteries are temperature and humidity. Generally, room temperature has little effect on the state of the lithium battery, but there should be no direct sunlight. High temperature will easily cause the model lithium battery to swell or explode, so Generally, the model lithium battery is stored in a metal box or plastic box that is protected from light and air.
