Abstract: A button-type battery including a package assembly and a cell assembly is provided. In actual application, as part of a sealing wall is recessed inwards in a direction to a battery reservoir so as to form a locking boss, as such, when a battery cover is being assembled, the locking boss is pressed against part of a sealing plastic ring so that the part of the sealing plastic ring is in tight contact with a sealing edge, and a battery cup can be locked to the battery cover by means of the locking boss, thereby preventing easy detachment of the battery cover from the battery cup to cause exposure of a rolled cell. The battery cover is applied with a strong locking force from the battery cup, greatly improving the safety of the button-type battery.
