てたもので使用前において電解液を注入し、初充電を行
わずして所定容重を確保できるようにした電池である。Conventional technology and its problems Ready-to-use lead-acid batteries are made by drying and assembling the electrode plates in a charged state, and by injecting electrolyte before use, it is possible to secure the specified capacity without initial charging. This is a battery that has been made into a battery.

歪のため極板変形を生じ、電池性能の劣化を招くおそれ
がある。Therefore, storage batteries have traditionally been stored in an airtight manner to prevent the electrode plates from coming into contact with the atmosphere and causing the active material to oxidize and lose its ready-to-use performance. As a result, the oxygen in the air inside the battery is consumed by the oxidation of the negative electrode plate, and the inside of the battery becomes depressurized by approximately 0.2 cm/- during storage, causing the battery case to become strangely deformed and deteriorating its aesthetic appearance as a product. . Furthermore, the distortion caused by the deformation of the battery case may cause deformation of the electrode plate, which may lead to deterioration of battery performance.

提供するものである。Means for Solving the Problems In the present invention, instead of making it completely airtight using an adhesive tape as in the past, the oxygen permeation rate at an oxygen partial pressure of 0.2 to 9/- is adjusted to the nominal capacity for one battery cell. II△0.01cc per h
/h or less by providing a gas permeable part made of a pinhole, porous material, or plastic sheet to slowly draw in outside air to prevent the battery from becoming excessively negative during storage, and By suppressing the amount of air intake within the permissible limit, the above-mentioned drawbacks of the conventional technology have been solved, and the ready-to-use type has been developed without significantly impairing the ready-to-use performance and causing almost no deformation of the battery container during storage. The company provides lead-acid batteries.
