Abstract
A battery operated device is equipped with one or more batteries each including a positive electrode, a negative electrode, a separator, and an electrolyte in a battery case. In this battery operated device, the battery has a gas vent that is opened due to an increase in pressure inside the battery case, and is configured to dispose the gas vent at a lower position thereof when installed in the battery operated device. Therefore, the battery function is ceased due to actuation of the gas vent.
