FIELD: electrical engineering.
SUBSTANCE: invention relates to perfectly tight storage battery. In compliance with this invention, the storage battery incorporates electrode terminals tightly fitted into the storage battery casing and partly extending there from, and polymer films arranged between the storage battery casing and electrode terminals. The said electrode terminals have preselected sections on their surfaces, whereon polymer film is applied, with irregular sites increasing adhesion between the said electrode terminals and polymer film and increasing the path of moisture contained in air or of storage battery electrolyte.
EFFECT: longer life of storage battery.
