Okay.
1. It is easy to carry, lightweight and multifunctional. SM interface battery uses high-performance lithium battery for power supply to meet the continuous, efficient and stable operation of the product.
2. Strong durability. SM interface battery adopts super large capacity nickel metal hydride, which can be recycled, explosion-proof and has strong power.
Generally, cell phone batteries have three connectors. In addition to the positive and negative terminals, what is the other one for?
Make sure the current direction is correct.
Lithium battery plugs are different in the forward and reverse directions. Lithium battery plugs have specific polarities. One is the positive pole and the other is the negative pole. The two interfaces of the angle grinder. Lithium batteries are different in ensuring charging. The device or deviceit is correctly connected and provides the correct direction of current for the load or power supply.
What does the p interface of lithium battery with fingerprint lock mean?
This pole is the temperature detection voltage output terminal. Cell phones use lithium batteries. Lithium batteries pose certain safety risks, so a temperature sensor is added inside the battery to monitor the temperature inside the battery core at all times. When the battery temperature is abnormal, a temperature sensor appears on the screen. battery poles. Usually, it is easy to cause the battery temperature to be too high during charging. At that time, charging stops automatically. When the mobile phone is working, when it detects this voltage, it will automatically shut down. down immediately to protectmanage the cell phone and the battery. This post is very useful.
Usually place the cell phone battery electrode up and facing you, with the battery end facing outward. The left one is positive, the right one is negative, and the middle one is the temperature electrode.
It's pretty clear.
The P interface of the fingerprint lock lithium battery interface actually refers to the positive terminal of the battery. In the lithium battery interface, the P interface refers to the positive electrode of the lithium battery, and the N interface refers to the negative electrode of the lithium battery. Since fingerprint locks are generally powered by lithium batteries, the positive electrode of the lithium battery should be connected to the P interface during use to ensure the normal operation of the lock.
