A deflectable battery retaining member in a battery powered unit blocks the improper insertion of a battery into the unit. Further, the same member in the absence of a battery inhibits engagement of the cover of the unit thereto providing a visual indicator of the missing battery. |

DETAILED DESCRIPTION In accordance with the invention, an electrical unit which can be powered at least in part by a battery includes a battery missing indicator.
The unit, which for example could be, but is not limited to, a battery powered smoke detector, has a base with an openable cover.
The cover can be hinged or completely removable from the base.
The base includes a deflectable member which is deflected from a non-locking position, in the absence of battery, to a locking position in the presence of the battery.
A blocking member is carried by the openable cover.
When the cover is placed in position on the base, assuming that the battery is present, the cover can be locked thereto.
When the cover is placed in position on the base, and the battery is missing, the location of the deflectable member keeps the cover from being locked to the base.
In one embodiment of the invention, the deflectable member urges the battery into contact with the unit's battery terminals.
The location and orientation of the deflectable member make it virtually impossible to improperly insert the battery.
In the absence of a battery the cover cannot be latched to the base and provides a visual battery missing flag.
In another embodiment, a blocking member carried on the cover will engage an improperly inserted battery and block closure.
If the battery is properly inserted, the cover can be closed and latched to the base.
Numerous other advantages and features of the present invention will become readily apparent from the following detailed description of the invention and the embodiments thereof, from the claims and from the accompanying drawings in which the details of the invention are fully and completely disclosed as a part of this specification.
