A battery cell module (10) comprises a battery cell having an outer case (11, 12, 13, 14) and terminals (16, 17) accessible from outside the case whereby the cell is electrically connectable to an external circuit. The outer case comprises key formations (14, 15) by means of which a plurality of the modules (10) can be held in place in a housing by interengagement of the key formations (14, 15) with further key formations of the housing. <IMAGE> |
