rechargeable batteries. They are a staple in the world of electronics because they pack a lot of energy into a relatively small, standardized cylindrical shape.
Based on the image, here is a breakdown of what those specs actually mean:
What the Labels Tell Us
18650: This refers to the physical dimensions. The "18" is the diameter in millimeters, "65" is the length in millimeters, and the "0" indicates it is cylindrical.
3.7V: This is the nominal voltage. When fully charged, these usually hit about 4.2V, and they shouldn't be drained below 2.5V to 3.0V.
2200mAh: This is the capacity (milliampere-hours). It tells you how much energy the battery holds. A 2200mAh battery can theoretically provide 2200 milliamps of current for one hour
