Zusammenfassung:	PURPOSE:To reduce the decrease in the amount of electrolyte so as to improve the life of a sealed lead storage battery used either in a trickle charging state or in a floating charge state by coating the surface of the battery jar with metallic foil having a very small steam permeability. CONSTITUTION:When constituting a sealed lead storage battery which is used in a trickle charging or floating charge state and in which oxygen gas produced during charging is absorbed by the negative plate, a member formed by affixing films 1 made of a polyester resin or similar material to the surfaces of metallic foil 2 with a thickness of 10-200mum made of aluminum or similar material is stuck to the surface of the battery jar by means of an adhesive 3. Therefore, due to the very small steam permeability of the metallic foil 2, the decrease in electrolyte can be suppressed even when charging is performed under a condition of high ambient temperature. As a result, the increase in the internal resistance and the deterioration of the capacity of the battery are alleviated, thereby improving its life.
