Why does the small cover run open when the battery is charged with water?

There may be several reasons why the small cover will collapse when the battery is charged with water:

1.The chemical reaction inside the battery produces a large amount of gas, which causes the internal pressure to increase, causing the battery liquid to vaporize.

2.When the battery liquid vaporizes, heat is released, causing the internal temperature of the battery to rise and the air pressure to increase, which further promotes the vaporization of the battery liquid.

3.When the air pressure inside the battery is too high, the battery fluid will be sprayed out of the battery fluid cap, resulting in the loss of battery fluid and the degradation of battery performance.

4.If the battery fluid cap is not strong enough, it may deform and rupture under the action of the internal air pressure of the battery, resulting in the loss of battery fluid.

5.The internal exhaust hole of the battery is blocked, resulting in the internal air pressure of the battery being unable to be released, causing the battery liquid to vaporize.

To avoid this from happening, it is advisable to pay attention to the following points when filling the battery with water:

1.Make sure the battery fluid cap and vent hole are not clogged or broken.

2.Avoid adding too much water, which can cause the battery liquid level to be too high.

3.Use the best battery fluid cap and vent hole to avoid the battery fluid cap from cracking when the air pressure is too high.

4.Let the battery sit for a period of time before adding water to allow the gas inside to fully release.

5.If the battery fluid cap is found to be cracked or blocked, replace the battery fluid cap with a new one or clean the vent hole in time.

In conclusion, in order to avoid problems when filling the battery with water, it is recommended to carefully check the condition of the battery before operation and follow the correct operation steps.

The amount of internal addition of the battery is limited, can not add more, check whether the exhaust hole is blocked, the battery is charged is electrical energy into chemical energy.

The internal temperature will boil and exhaust will be carried out, so the abnormal phenomenon will occur, I hope you!

It's that you add too much water. It should be added according to the standard. Otherwise, it is easy to damage the battery. Or find a professional to add it to you.

Summary. Hello, you don't need to open it, you need to cover the lid after the battery is refilled, and the liquid of the battery is specifically corrosive to prevent overflow and volatilization too quickly.

Hello, you don't need to open it, you need to cover the lid after the battery is refilled, and the liquid of the battery is specifically corrosive to prevent overflow and volatilization too quickly.

Dear, if it is an ordinary battery, there will be a cover with water on the battery, and you can unscrew it; The general maintenance-free battery, you need to drill it on the top by yourself, seal it after adding water, add water to submerge the plate for 1 cm, distilled water or pure sensitive hidden water can be, but tap water and mineral water are strictly prohibited. When the battery is charged after the water is charged, the battery voltage decreases, but the capacity increases.

Then some people say that they want to unscrew it, because they are afraid of a lot of heat and gas.

Pro, the battery can not be charged immediately after adding water, distilled water or purified water, and it can only be charged when it needs to be burned to be stationary for 1-2 small yards, because after adding water, it needs to be completely fused with dilute sulfuric acid of the original battery liquid, so as to ensure the quality of battery charging. Of course, for some new batteries and stock solution, it can be charged immediately, after all, the solution inside does not need to be fused.

Oh, the second addition should be still for a while before it can be charged.

Pro, there is a vent hole on the lid of the liquid filling hole, as long as the vent hole is not blocked, you can cover it, and the dust can be prevented from entering after the cover.

You're talking about this little hole.

Yes, dear. Good.
