There are many things that can cause the battery to get hot
Causes of heat caused by lithium batteries:
1. When the battery voltage is 0, the internal resistance of the battery will become very large, and it will consume a lot of current when charging, and even the current of your charger is not enough for it to consume.
2. After the battery reaches 0 voltage, the liquid inside the battery becomes dry. During the charging process, the dry material reacts violently and generates heat.
3. After the battery voltage is 0, there may be a micro-short circuit in the internal pole piece, which makes the battery self-discharge continuously and emit heat.
The main reason why the flashlight is hot is due to the lamp bead and the IC or capacitor.
The lamp beads commonly used in flashlights are CREE lamp beads, Jingyuan and other brands. Like the lamp beads used by our company are all CREE lamp beads,
First, the brightness is strong. withstand high current.
Second, the lifespan and performance of lamp beads are better than other brands. If the current of the lamp bead is 1.2A. If the flashlight achieves 1A, the current is too large. He needs to dissipate heat from the outside. If a 350Am current is used, the flashlight will not be hot. However, the effect of brightness also decreased. It is a normal phenomenon that the flashlight is hot, but if it is very hot, it should be turned off and let it buffer.
In the process of using the flashlight, some flashlights will cause the body to become hot. This is also a normal phenomenon. Whether it is an explosion-proof flashlight or an LED flashlight, the principle of its composition is the same. The performance of the lamp beads and other components causes the flashlight to become hot. The flashlight is hot because the realization of the highlight function requires high-power energy to drive, and the LED will generate a certain amount of heat when driving, which is a normal phenomenon.
