An upright battery seat for a button battery includes a base and positive and negative terminals each having an elastic arm located in a slot and electrically connected to the battery, a positioning portion positioned with the base, and a pin portion extending out of the base. The base has a circumferential wall and a longitudinal placement surface to form the slot. The wall is formed with an opening and first and second engagement portions. The first and second engagement portions engage with two side edges of the battery. The first engagement portion has an engaging surface substantially perpendicular to an inner surface of the wall. The arm of the positive terminal projects over the inner surface and enables one side of the battery to engage with the engaging surface. When the battery is pressed down, the side edge of the battery can escape from the engaging surface without locking.
