Abstract
Disclosed is a battery casing comprising a diametrical can, a recoverable sealing ring, sealing material and a central member. The diametrical can has a flange portion which defines a can opening to be sealed. The can opening is filled by insertion of the central member and sealing material into the can opening. The recoverable sealing ring, which surrounds the flange portion, applies a compressive force so as to decrease the space between the flange portion, sealing material and central member and seal the can opening.
