Abstract: A battery seat has a base, a positive terminal and a negative terminal. The base has a bottom, a sidewall, a positive terminal seat, a negative terminal seat and a battery cavity. The sidewall, the positive terminal seat and the negative terminal seat are formed on the base, extend up from the base, are connected to each other and form the battery cavity. The positive terminal is mounted on the positive terminal seat. The negative terminal is mounted on the negative terminal seat. Because the sidewall, the positive terminal seat and the negative terminal seat are connected to each other and to the bottom of the base, the battery cavity is strong and robust. Even a significant crack in the sidewall will not degrade the integrity of the battery cavity, and the battery cavity will still hold a battery without letting the battery fall from the battery seat.
