(1) Do not short circuit: There are many reasons for short circuits, which can be divided into positive electrode material leakage, poor battery quality, internal crystallization, positive and negative pole contact, etc. For us, what we often encounter is a short circuit in contact between the positive and negative poles, which is caused by an operational error. The positive and negative poles of the battery are directly connected through conductors, and the result is very dangerous. Depending on the short circuit situation, many dangerous situations can occur, such as liquid leakage, spontaneous combustion, explosion, etc. Be sure to pay attention to safety in daily use, and keep conductors away from power lines, etc.

　　(2) Do not damage the battery with sharp objects: Sharp objects can puncture the surface of the battery and cause liquid leakage, which can lead to the combustion of the lithium battery.

　　(3) Correctly grasp the safety status of lithium batteries: As mentioned earlier, each individual has a significant impact on the overall situation, so it is required to correctly grasp the safety status of lithium batteries during use. It is recommended to connect a voltage alarm (BB sound) when using it, and remember to connect it correctly. The ground wire and voltage wire should correspond separately. This type of voltage alarm can be set to a lower operating voltage to remind users to charge in a timely manner. It can also display the voltage situation of each battery, allowing users to have confidence in safety.
