18650 batteries, how much lower the discharge voltage will affect the life
The minimum end-of-discharge voltage of the 18650 battery cell is generally: 2.75V. Under normal circumstances, when the voltage drops to 0.875 times the rated voltage (3.24V), it should be charged. If you continue to use it, the voltage will drop rapidly, and it may be damaged due to over-discharge, which will affect the life.
18650 is the size model of the battery, which refers to a cylindrical battery with a diameter of 18mm and a length of 65mm. According to the type of battery, it can be divided into 18650 for lithium ion, 18650 for lithium iron phosphate, 18650 for nickel metal hydride (rare), and the common 18650 is lithium ion.
The 18650 battery used for notebook computers usually has a capacity of 2200mAh (mAh), the voltage is: 3.7V, the current is 2200mA, and it can be used for 1 hour. The battery cell usually refers to a single cylindrical battery.
