14500 lithium battery is a kind of lithium battery with a diameter of 14 mm and a height of 50 mm. It can be divided into lithium iron phosphate battery and lithium cobalate battery according to the cell material. The voltage of lithium cobalate battery is 3.7V, and the voltage of lithium iron phosphate battery is 3.2V. Since its size is the same as that of AA 5 # battery, one 14500 lithium battery and one space occupying barrel can be used instead of two AA batteries. Compared with NiMH rechargeable battery, lithium battery has the advantages of light weight, less self discharge and superior discharge performance. Therefore, it is widely used by photography enthusiasts in digital cameras and electronic cigarettes to replace NiMH rechargeable battery. How about the endurance? It should be OK. It depends on what appliances you use and the frequency, intensity and duration you use. Its nominal capacity is 1600mAh.

　　The industry-leading 14500 lithium battery manufacturer can customize 14500 lithium battery packs of various specifications according to customer needs. Here are three common questions about 14500 lithium battery:

　　1.14500 shopping problems

　　As the voltage of lithium battery is (2.5V - 3.7V), overdischarge or overcharge will damage the battery, so the battery with protective plate can be protected. I don't think so. Because the 14500 battery with the protective plate is about several mm higher than the ordinary No. 5 cell, some camera covers can't be covered, and the battery contacts that can be covered can also affect the camera. Over time, the elasticity will drop, causing poor contact. Another protective board can not play the maximum energy efficiency of the battery, because the protective circuit is at 2. When the power is cut off automatically at 5V, the camera will be cut off suddenly and will not shut down automatically, which may cause loss to the camera.

　　2.14500 over discharge

　　In the general question of minimum voltage without protective plate, some details should be noted:

　　*The voltage range of the camera. Generally, the camera voltage is 2.4V to 4.2V

　　Therefore, the camera will often shut down when the voltage reaches 2.4V. The camera has a choice of battery type (alkaline, nickel battery, lithium battery). The shutdown voltage is different when different battery types are selected. As long as lithium battery is selected, its shutdown voltage is 2.6V. The 2.5V battery without protective plate is a safe voltage, so there is no over discharge problem, and it can also play the maximum energy efficiency of the battery. (determined according to its own camera)
