The numbers on a battery typically indicate its size, capacity, and specifications. For example, in a battery like "18650," the "18" refers to the diameter in millimeters, "65" to the length, and the "0" signifies it is cylindrical. Other numbers or codes may denote the battery's voltage, capacity in milliamp-hours (mAh), or specific model and manufacturing details.
