The numbers on a battery typically indicate its size, capacity, and specifications. For example, common designations like "AA" or "18650" refer to the physical size and shape, while numbers such as "1500mAh" indicate the battery's capacity, meaning how much charge it can hold. Additionally, you might find voltage information, such as "1.5V" or "3.7V," specifying the battery's electrical potential.
