Several Key Factors That Affect the Cycle Life of 18650 Lithium Batteries

Depth of charge and discharge: Generally speaking, deep charge and discharge cycles will cause the battery capacity to decay faster, thereby shortening the cycle life. Therefore, controlling the depth of charge and discharge and avoiding excessive charge and discharge will help to prolong the cycle life of the 18650 lithium battery.

Charge and discharge rate: High rate charge and discharge will lead to drastic changes in the internal chemical reaction of the battery, accelerate the process of battery capacity decay, thereby shortening the cycle life. Therefore, operating the battery within a reasonable range of charge and discharge rates can prolong the cycle life.

Temperature: Temperature is one of the important factors affecting the cycle life of lithium 18650 rechargeable battery. Controlling the operating temperature of the battery within an appropriate range helps to prolong the cycle life.

Charging management system: A reasonable charging management system can provide proper charging control and protection functions to prevent abnormal conditions such as overcharging and overdischarging, thereby protecting the battery and extending cycle life.
