PURPOSE:To increase the life and the performance of the retainer battery by pouring electrolyte into a storage battery, which is assembled by installing a positive or negative plate in each sack-like retainer formed by a nonwoven fabric of inorganic or organic fiber, until the plates are immersed up to their specified height. CONSTITUTION:After each retainer 1 consisting of a nonwoven fabric of inorganic or organic fiber is formed into a sack, a positive or negative plate is installed in the sack thereby assembling a storage battery. Electrolyte 3 is poured into the battery until 1/10 to 1/2 of the height (H) of the plates is immersed so that the lower part works as a liquid-type battery and the upper part works as a retainer battery. By using the sack-like retainer 1, any short circuit of the negative plate 5 which might be caused due to production and growth of dentrite is prevented and free electrolyte 3 is held in the retainer 1. As a result, it becomes possible to decrease the specific gravity of the electrolyte 3 and increase its amount. Additionally, by adjusting the height (h) of the liquid level of the free electrolyte 3 to 1/10 to 1/2 of the height of the plate, the efficiency of sealed reaction is maintained at a level of at least 90% and therefore it is possible to increase the cycle and the trickle life performances. |
