Open the battery cover and remove the six hard hats
< br >
Use a syringe to fill each hole with distilled water. If 1.28 standard electrolyte is added, the plate may burn out due to excessive acid dissolution. For example, we eat hot pot, why will eat more salty, that is, when the water evaporates, the salt will not evaporate through the water steam, the same reason, the acid in the battery will not be evaporated, the missing is water, so we just add about 20-30ml of distilled water in each hole.
< br >
After filling, let the battery rest for half an hour, so that the sponge body around the plate can fully absorb water. Then use resistance discharge, put the battery in the electricity, all put out, no resistance, you can use a 12v bulb instead, such as: motorcycle headlights, car turn signals can be used, as long as it can discharge to 0v. How to judge the battery is close to no electricity, cement resistance discharge at the beginning of the resistance body hot, slowly gradually not hot, then the battery is out of power. The light bulb, but also directly, as long as the light slowly does not light, it shows that the battery discharge is over, the discharge time depends on the capacity of the battery discharge, we can first ride the battery to no power and then maintenance, which can shorten the discharge time.

After the end of the discharge to charge the battery, conditions can be used pulse charging mode, because the pulse charging mode can effectively remove the vulcanization of the plate and improve the capacity of the battery. What you don't have can be replaced with a car.

When the charge is complete, use the syringe to drain the excess water from each hole. A total of six holes, step by step to complete.

Close the cap and lid, ready to load the car
The lack of distilled water in the battery can be solved by the following methods:
< br >
Add distilled water. Open the outer cover of the electric vehicle battery, pry open the water cover of the battery, use a medical needle to extract distilled water, inject it into the battery, and finally use the charger to charge the battery.
Replace the battery. If the battery water shortage is serious, adding distilled water cannot restore the battery capacity, and the battery needs to be replaced.
< br >
Add distilled water to the battery car battery is recommended to professional maintenance shops or manufacturers for operation, to avoid improper operation to damage the battery or cause safety accidents.
Electric tricycle battery lack of liquid, is the battery sulfuric acid in the distilled water dried up, open the battery has 2-- 3 rubber caps, after taking out the needle bucket injected distilled water can be, pay attention not to the distilled water injected full, and then plug into the power supply to charge, if the liquid can be extracted, for the liquid does not emerge, pay attention to the power operation, and then cover the rubber cap, Restore the original can be, it is best to lie flat when charging, that is to say, the part of the battery rubber cap is facing up, so that the electrolyte flow is better, distilled water in general bathhouse, you can also ask about other aspects.
The answer is as follows: If the electric car battery is out of water, it is necessary to add distilled water or pure water in time. The specific steps are as follows:
< br >
1. Open the electric car bottle cap, check the internal liquid level of the battery, if the liquid level is lower than the minimum mark line, you need to add water.
< br >
2. Using distilled water or purified water, pour the water into the battery, taking care not to exceed the highest mark line.
< br >
3. After adding water, cover the electric bottle and start the electric vehicle.
< br >
4. In the process of driving, pay attention to observe the battery level, if it is found that the liquid level drops too fast, it is necessary to check whether the battery leakage and other problems.
< br >
It should be noted that the electrolyte in the electric vehicle battery is a strong acid, and careful operation is needed when adding water to avoid splashing on the skin or clothing. At the same time, the liquid level inside the battery should not be too high or too low, too high will lead to an increase in the internal pressure of the battery, too low will affect the life of the battery. Therefore, when adding water, it is necessary to operate according to the standards on the battery manual.
