ABSTRACT:
A battery holder for a button-type battery (1) includes a holder body having a base wall (100) thereof for receiving the battery, and positive and negative terminals (20, 30) assembled to the holder body. The negative terminal has short and long spring elements (311, 315) defining first and second supporting point (311A,315B) respectively, such that in an initial released position, the button-type battery is lifted up by the first and second supporting points bearing against the base wall, and in a fully released position, that battery is lifted by the second supporting point against the base wall with the first supporting point leaving away from the base wall. The above spring elements provides two-stage elastic forces, for ease of the user to release the battery from the battery holder.
