術が提案されている。2. Description of the Related Art Lead-acid batteries generate hydrogen and oxygen gas at the end of charging. If there is an ignition source, rapid combustion will occur, and in some cases, the battery may be damaged. On the other hand, there are quite a few cases of battery damage that are thought to be caused by static electricity. According to experiments, battery damage does not occur even if a static electricity voltage of 20 kV or more is applied to the container or lid, but battery damage occurs even at 15 kV if a static electricity voltage is applied to the area around the liquid spout plug. Therefore, battery damage due to static electricity is thought to be caused by discharge sparks entering the battery from the area around the liquid spout plug. In response to this, techniques have been proposed in which a label is used to cover the liquid spout to prevent discharge sparks from entering, and an antistatic material is used in the lid to eliminate static electricity.

くできず、静電気除去の効果も低かった。[Problems to be Solved by the Invention] However, when a label is used to cover the liquid outlet plug, high static electricity is generated when the label is peeled off when refilling the battery with water, causing damage to the battery due to discharge sparks. On the other hand, the technology that uses antistatic material for the lid is
Because of the need to suppress electrical leakage between the positive and negative terminals provided on the lid, the resistivity of the antistatic material could not be made very low, and its effectiveness in removing static electricity was also low.

損を招くことはない。In FIG. 1, the covering 1 has a diameter of 1,000,0
The coating 1 is an antistatic material with a specific resistance of 00 Ω·cm and is made of a resin containing a surfactant. It is applied to cover the periphery of the stopper 2. Even if electrostatic charge and discharge sparks occur around the liquid port plug 2, they are immediately absorbed by the covering 1 and then removed to the outside of the battery.
Discharge sparks will not enter the battery from around the liquid port plug 2 and cause damage to the battery.

。When the covering 1 is connected to the negative terminal 4, the static electricity absorbed by the covering 1 is immediately grounded to the automobile body through the negative terminal 4, thereby further enhancing the charge removal effect.

The cover 1 may cover the periphery of the liquid spout 2 and may be connected to an automobile body including a battery fastening fitting. In either case, the same effects as those of the embodiments can be produced without needing detailed explanation.

が望ましい。The specific resistance of the coating 1 is 100,000,0
If it is more than 00Ω・cm, it will become an insulator and the antistatic effect will be weak. If it is less than 10,000Ω・cm, it will become a conductor. For example, if a metal object such as a screwdriver is
If it is interposed between the cover 1 and the cover 1, a short circuit may occur. Since the distance between the terminals and the surrounding area of the liquid port plug 2 is small, the risk of short circuiting increases. Therefore, the specific resistance of the coating 1 is 10,000 to 100,000,000Ω・cm
is desirable.

In addition, despite having high static electricity removal properties, positive
The negative terminal is insulated and there is no electrical leakage. In addition, since an antistatic material with relatively high resistivity is used for the coating, there is no risk of short circuit between the positive and negative terminals.
