。However, since the material of this type of battery case is polypropylene resin (hereinafter referred to as PP resin) or acrylonitrile-butylene ethylene resin (hereinafter referred to as ABS resin), the water vapor permeability is 0.1 to 3 at 25°C. .0 meeting/24-
In addition, because there is a large space between the plate group and the battery case, the surface of the battery case during trickle charging or floating charge is higher than that of conventional open lead-acid batteries, where the plate group is filled with electrolyte. A large amount of water evaporates, which is the main reason for the decrease in electrolyte solution.

形鉛蓄穎、ｌΦに比べて短かい原因となっていた。As shown in Figure 1, the decrease in electrolyte is expressed by the relationship between electrolyte volume C and capacity A during trickle charging at an ambient temperature of 25°C, and between electrolyte decrease position and capacity port at 40°C. , which is accelerated as the ambient temperature of the battery increases, leading to an increase in the internal resistance of the battery, a decrease in discharge capacity, and an increase in lattice corrosion due to concentration of the electrolyte, which reduces the lifespan of sealed lead-acid batteries used in trickle charging and floating charging. This was the reason why the length was shorter than that of the conventional open lead-acid tube.

を示す。In Figure 4, the metal foil is a 20ttm aluminum foil, the resin film is a 50μm thick polyvinyl chloride resin adhered to both sides of the aluminum foil with an epoxy adhesive, and the voltage is 12V with an acrylic ester adhesive. The curvature surface area of a sealed lead-acid battery with 3Ah specifications was 9 times 10 times, 25%, and 80 times, respectively, and the ambient temperature was 60°C.
The figure shows the decrease in electrolyte and the change in capacity when performing trickle charging at a charge voltage of 13.8V in comparison with a conventional product.A metal foil sheet 1- is pasted on 80% of the surface area of the battery case. Metal foil sheets were pasted on 26% of the surface area of the battery case. It shows the characteristics of the capacity and the amount of fluid loss of the attached battery, as well as the characteristics of the amount of fluid loss (E) and capacity (A) of the conventional product.

びている。These results show that when aluminum foil (bamboo) metal foil is attached to the surface of a battery case, the decrease in electrolyte decreases in inverse proportion to the surface area of the battery case, and that covering approximately 25% of the surface area of the battery case with aluminum foil is effective. As can be seen, when approximately (a) of the surface area of the battery case excluding the battery terminal sound W and air opening is covered, the battery weight decreases, that is, the electrolyte volume decreases by 50 to 6% compared to the conventional product.
0, and the life of the electro-oil solenoid is 1.5 to 2 times longer than that of conventional products.
