Capacity fade

Capacity fade refers to the gradual reduction in a battery's ability to hold and deliver charge over time. Just like a sponge that becomes less effective at soaking up water after repeated use, a battery experiences chemical and physical changes with each charge and discharge cycle. This leads to a decline in performance, meaning it won't power devices as long as it used to. Factors like temperature, cycling frequency, and charging habits can accelerate capacity fade, impacting the battery's lifespan and overall efficiency. Understanding this phenomenon is crucial for better battery management and maintenance.
