This part of the car is inspected from time to time

The embankment of a thousand miles was destroyed by an ant nest, and this part of the car is inspected from time to time

The battery is an important power source responsible for starting the car, and its quality is directly related to whether we can start it normally. car. Do you know the dangers of battery leakage? How to avoid losses caused by battery leakage? Today, we will talk about the destructive power of battery fluid through this case of battery leakage.

1. Why do batteries leak?

Most car batteries are lead-acid batteries, and the main medium for charging and discharging is electrolyte. The electrolyte is a fluid, so there are requirements for the sealing performance of the battery. However, during the charging and discharging process, the battery is inflated and heated, so it must be consistent with the atmosphere. Therefore, once exposed to high temperatures caused by excessive power generation, the electrolyte may boil and leak, or the housing may be poorly sealed and cause leakage.

2. How destructive is the electrolyte?

The electrolyte contains hydrochloric acid. The solubility of hydrochloric acid is not high, but it is enough to corrode paint surfaces, rubber and other substances. From the case of this car, it can be clearly seen that the hose and paint surface corroded by the battery fluid spilled have different degrees of corrosion, which is quite destructive.

3. Does leakage mean battery damage?

This is not necessarily the case. We can check the status of the battery at this time through the observation hole on the upper part of the battery.

1. Leakage caused by poor sealing of the casing: the battery needs to be replaced.

2. Excessive power generation leads to leakage: the power generation problem can be solved without replacing the battery.

4. How to distinguish the cause of the leak?

1. Leakage from the upper cover: The inside of the upper cover is a cover filled with electrolyte. If leakage occurs from this part, it is suspected that the leakage is caused by the battery fluid boiling due to too high power generation.

2. Leakage at the shell connector: This part is the connector of the battery shell and is a one-time connection. If there is a leak here, the battery should be replaced.

5. How to deal with parts contaminated by battery fluid

1. Cleaning personnel should wear protective glasses and protective gloves when operating.

2. Replace corroded hoses.

3. For the corroded paint surface, rinse it with clean water, then polish the corroded surface and spray again.

4. If the screws are corroded, replace them seriously and apply grease after minor cleaning.

6. Battery fluid has the greatest destructive power on colloids

Rubber is extremely sensitive to corrosive media, but it will not be corroded in the first place. Once battery fluid splashes onto the hose and is not cleaned in time, corrosion will occur over several days, causing serious consequences as shown above. If it is a trachea, it will cause air leakage; if it is a water pipe, it will cause water leakage.

7. Regularly check the power generation situation

1. Normal power generation: between 14v and 14.9v.

2. High power generation: above 15V.

3. Normal battery voltage: statically higher than 12.5 volts. If it is lower than this value, it may be possible. If it is higher, it may be that the power generation is too high, leading to oversaturation charging.

Written at the end:

For common lead-acid batteries, their status is relatively stable and there will be no serious safety hazards. But the problem of battery leakage has far-reaching consequences. If we do not develop a good habit of regularly checking power generation, we will not deal with battery leaks as soon as possible, which will lead to corrosion of parts. Leakage is not terrible, what is terrible is irregular inspection. Have you learned it?
