がある。Prior art and its problems In recent years, in order to prevent self-discharge and gas generation at the end of charging, a positive electrode plate using a grid made of a lead-antimony alloy, as shown in E3 Dai in Japanese Patent Application Laid-open No. 49-133841, has been developed. Lead Wv & Ponds, which have a negative electrode plate using a lead-calcium alloy lattice, have come to be used. When employed in a sealed lead-acid battery having an electrolyte that is almost retained and substantially non-fluidized, there are the following drawbacks.
（１）放電深度が８０襲を超える深い放電をともなう充
放電を繰り返すと寿命が短かくなる。(1) Repeated charging and discharging accompanied by deep discharges with a depth of discharge exceeding 80 cycles will shorten the lifespan.
（２） 放電深度が８０％を超える深い放電を行なま

It is equipped with a positive electrode plate using a grid made of a lead-antimony alloy containing antimony and a negative electrode plate using a grid made of a lead-calcium alloy, and has a density of 2.5 to 5.59/d. This is a sealed lead-acid battery that uses an active material of this type for the positive and negative electrode plates.

Most of it is retained in the negative electrode plate and the separator made of fine fibers. Therefore, 1! The solution is substantially non-fluidized. Moreover, the positive and negative electrode plates have 2.5 to 5.
It is filled with an active material having a density of 59/-.

が改善されると寿命も改善される。Next, a comparison will be made between the sealed lead acid battery of the present invention and a conventional sealed lead acid battery. Table ta1 shows the results of a deep discharge life test and a JIS charging acceptance test for the sealed lead acid battery of the present invention and the conventional sealed lead acid battery. As is clear from the fJ1 table,
Even after repeated deep discharges with a depth of discharge exceeding 80%, the sealed lead-acid battery of the present invention is superior in both the number of life cycles and charge acceptance performance compared to the conventional example and comparative example (1).O General sealed lead-acid battery The cause of the lifespan is due to sulfur VB of the electrode plate due to deterioration of charge acceptance performance. Therefore, as in the case of the sealed lead-acid battery of the present invention, when the charge acceptance performance is improved, the life span is also improved.
また、活物質の密度を２．５９７４以上に規定している
のは、活物質の密度を２．５９／ｃ４未満にしても電池
性能が飛躍的に改善されることがないのと、極板の製造
時に極板不良が増加するためである。In addition, the reason why the density of the active material is specified to be 2.5974 or more is that even if the density of the active material is less than 2.59/c4, the battery performance will not be dramatically improved. This is because the number of electrode plate defects increases during manufacturing.
更に、本発明の正極板格子体合金のアンチモン含有量が
、３重量％を超えると電池の自己放電が増加して好まし
くない。Furthermore, if the antimony content of the positive electrode plate lattice alloy of the present invention exceeds 3% by weight, self-discharge of the battery will increase, which is undesirable.
なお、上記ＪＸＳ充電受入性能は、充Ｗｔ開始１０分後
