Battery cell housing
 Described is a two-part housing for a battery cell having circuitry separate from the main body of the cell. Finger joints, blind dado joints, and edge joints with rabbeted edges are disposed in the mating region between the two halves of the housing. An insulating and alignment wall is integral with one half of the housing, and fits in the channel between the main body of the cell and the circuitry. The housing is dimensionally stable, provides mechanical protection for the delicate cell circuitry, and the two halves of the housing may be secured using only a label wrap.
