18650 배터리의 수명을 늘리려면 어떻게 해야 하나요? Posted by batterymanufactory.com
18650 batteries are widely used in various electronic devices due to their high energy density and long cycle life. However, the number of cycles of a battery is not fixed and is affected by many factors. This article will analyze these factors in detail and provide practical suggestions for extending battery life. I. Definition of the number of cycles of 18650 batteries The number of cycles refers to the process of a battery completing a 100% charge and discharge. For example, a battery is used from 100% to 50% and then fully charged to 100%, which is only counted as 0.5 cycles. II. Factors affecting the number of cycles of 18650 batteries Battery quality: High-quality batteries use high-quality materials and advanced processes, and the number of cycles can reach more than 500 times, while inferior batteries may only have 200-300 times. Depth of charge and discharge (DOD): Deep discharge (such as less than 20%) will accelerate battery aging, while shallow cha...
