Explanation of lithium battery parameter names
I. Fundamentals: Capacity, Energy, and Density Many people’s first confusion about lithium batteries is the misconception that “large capacity = long battery life.” In reality, both capacity and voltage together constitute the battery’s energy. 1. Capacity: Unit: Ah (ampere-hour) or mAh (milliampere-hour), 1 Ah = 1000 mAh. Defined as the total amount of electricity a battery can output under specific conditions, the physical formula is Q = I × t (current × time). The capacity varies significantly depending on the
