The numbers on a battery typically indicate its size, capacity, and specifications. For example, a battery might have a number like "AA" or "18650," which refers to its size and shape. Additionally, other numbers such as voltage (e.g., 1.5V, 3.7V) and capacity (measured in milliampere-hours, mAh) provide information about the battery's power output and how long it can last under specific conditions.
