Abstract
Described is a battery cell housing comprising a battery cell compartment and a latching compartment separated by an inner wall, where the battery housing is made of metal formed by combination extrusion or dual impact extrusion. This permits battery compartment wall to be thin, so that the maximum size battery cell may be inserted into it, and the latching compartment wall to be thic,k so it can be securely fastened to an electronic device. The inner wall provides an impenetrable barrier to moisture migrating from the latching compartment to the battery compartment.
