18650 Battery is originally referring to a nickel-hydrogen battery and a lithium ion battery. Since nickel hydrogen is more useful, therefore, a lithium-ion battery is now referred to. The 18650 lithium-ion battery single-section sign voltage is generally: 3.

6V or 3.7V; minimum discharge termination voltage is generally: 2.75V.

The common capacity is 1200 ~ 3000mAh, which is very likely to be dummy. Since Sony launched since the 1990s, 18650 batteries have been done. 18650 battery is widely used in industrial fields and laptops, walkie-talkies, instrumentation and other electronic devices, etc.

Why does the lithium ion battery explode? 18650 Battery Most of the steel shell package, the battery is not high, because there is no protection function, in the case of overcharge (overcharge), the internal pressure increases, when it exceeds the tolerance, it will explode. The short circuit, too high, or the battery is extruded or even piercing, etc.

may cause the battery explosion. Good quality 18650 bathing is no problem (do not imitate, unless you have a mine) What is a lithium-ion battery safety valve? After 30 years of development, the 18650 battery preparation process has been very mature. In addition to performance, its security is also very perfect.

In order to prevent the sealed metal housing, the 18650 battery is now equipped with a safety valve at the top, and the safety valve is the standard of each 18650 battery and the most important explosion-proof barrier. When the internal pressure is too large, its top safety valve opens the exhaust pressure to prevent explosion. When the safety valve is turned on, the chemical that is disclosed inside the battery will chemically react with oxygen in the air, and there may be a very low probability that the cruises are fire.

In addition, some 18650 batteries are now self-contained, with overcharge and short-circuit protection, with high security performance. Safety valve is broken, the previous power explosive event is basically due to unscrupulous manufacturers to save costs of inferior 18650 batteries.
