Abstract

A vented filling plug for an electric storage cell has a vent path including a flame trap through which gas may enter or leave the cell arranged so as, in use, to communicate with the interior of the cell at a point above the normal electrolyte level. The flame trap includes a liquid trap defined by a trough 31 and a tubular partition 30, and a ceramic partition 33. The plug also has a filling path through which electrolyte may be poured into the cell arranged so as, in use, to communicate with the interior of the cell at a point below the normal electrolyte level. The filling path includes a liquid trap defined by trough 40 and partition 34 below the normal electrolyte level. <IMAGE>
