On the other hand, button top 18650 batteries have a small protrusion or "button" on the positive terminal. This button serves as a raised positive contact point, allowing the battery to make contact with spring-loaded battery compartments or devices that require a button top battery. Button top batteries are commonly used in certain flashlights, some older portable electronics, and certain types of power tools.
