Housing for a Replaceable Stored Energy Source with a Connection Option for Supplying Power to an Electronic Device That Can Be Connected Thereto, and Wireless Hazard Detector

Various embodiments include a housing comprising: a shaped receiving compartment for receiving a stored energy source in the housing interior; a connection option for supplying power to an electronic device connected to the stored energy source; a main body; and a closure part movably attached to the main body. The main body is configured to be removably mounted on a mounting surface. When the main body is mounted and open, there is an access opening to the receiving compartment to allow removal of the stored energy source and insertion of a replacement. The housing includes a retaining device for removably attaching the stored energy source to the retaining device. The retaining device is configured so the stored energy source can be removed from the retaining device in a direction away from the mounting surface and can be attached to the retaining device in a counter-direction towards the mounting surface.
