Battery acid leakage is a common safety hazard in various power supply equipment. If it is not handled properly, it may cause multiple dangers.

Whether it is a dry battery used in daily life, a vehicle battery, a large industrial power storage device, once acid leaks, it may cause not only equipment failure and contact surface corrosion but also threaten to human health.

Timely detection of leakage and taking correct response measures are the keys to ensuring personnel safety and maintaining normal operation of the power supply.

This article will analyze the identification method of electrolyte leakage in detail, explain the safe cleaning process and disposal methods step by step, and provide effective measures to prevent battery leakage, helping to prevent battery leakage in daily use.

Part 1: What is Battery Acid Leaking

The literal meaning of battery acid leakage is very easy to understand, eso es, the liquid inside the battery overflows from the battery shell.

The liquid inside the battery is the electrolyte used to maintain the charge and discharge inside the battery, or a series of other related solvents, etc..

When the battery acid leaks from the sealed battery shell due to various factors, it will not only affect the normal operation of the battery but also the performance and life of the battery that has leaked the battery acid will be significantly reduced.

Además, most battery acid is corrosive and pungent, which will pose a threat to the surrounding environment and human health.

Part 2: How to Identify Battery Acid Leakage

Battery acid leakage will have a very large impact on the human body and the surrounding environment, so if you want to identify battery acid leakage, we can do it from 3 aspects:

1. Appearance inspection

Direct observation. Directly check whether the battery shell has obvious damage, cracks, and deformation. Damage to the battery shell will directly lead to electrolyte leakage inside the battery. When checking, you can focus on the positive and negative areas of the battery and the interface where the battery connects to the device, because these places need to connect more other parts to maintain good conductivity, so they will be a little fragile.

Color change. When some batteries leak battery acid, it is likely to cause the battery shell and the surrounding area to change color. La mayor parte del tiempo, white or crystalline substances will appear.

Battery expansion. During the use of the battery, some gas will be released. If too much gas is released from the battery in a short period, the battery will swell. En este momento, the expansion of the battery may not necessarily leak the battery acid, but once the battery swells, it is easy to leak the battery acid which requires close attention.

Dampness. When the battery acid leaks significantly, the surface of the battery is easy to feel damp and sticky.

2. Actuación

Reduced battery life. When the battery life suddenly drops sharply and it is difficult to recover through normal charging, the battery acid has likelyleaked.

Abnormal charging. Durante el proceso de carga, the battery will heat up, but if you find that the battery heats up severely, please stop charging, it is very likely that the battery acid has leaked. And if the charging speed is too fast or too slow, you should also be vigilant and stop charging.

Voltage floating. Use a multimeter or other voltage test tool to detect the battery voltage. If the battery voltage is unstable or continuously decreasing, it is possible that the battery acid has leaked.

3. Olfactory identification

Pungent smell. When the battery acid leaks, it is easy to emit a pungent smell because the main component of the battery acid is chemical substances. When the battery has a noticeable pungent smell when in use, please stop using it immediately.

Burning smell. If the cause of the battery acid leakage is battery overheating or a short circuit, some of the substances in the battery acid will likely burn and produce a burning smell. This is already a critical moment. It is necessary to immediately cut off the power supply and take fire extinguishing measures.

Part 3: Causes of Battery Acid Leakage

There are many reasons for battery acid leakage. This article systematically summarizes some common reasons, which are generally divided into the following 2 aspects:

1. Battery structure

Damaged shell. During transportation and use, the battery may be hit or squeezed, causing the battery shell to rupture and the battery acid to leak.

Manufacturing defects. During the manufacturing process of the battery shell, if the structure is unreasonable, the process is poor or the material quality is poor, it is very likely that small cracks and holes will appear in the battery shell. En este caso, the battery will easily leak if it is used for a long time.

Poor or aging sealing materials. The sealing of the battery liquid is very dependent on the sealing material, and the common ones are sealing rings and glue. If the sealing material is not selected well and used for a long time, it is easy to age and deform, causing the sealing material to lose its sealing effect, resulting in battery acid leakage.

2. Reacción química

Overcharge and over-discharge. If the battery is overcharged, the chemical reaction inside the battery will be out of control, and a large amount of gas will be generated, resulting in increased pressure inside the battery, and the battery sealing structure will be destroyed, resulting in battery acid leakage.

Over-discharge of the battery can easily cause corrosion of the battery's electrode material, produce solid substances such as crystals, and make the positive and negative electrodes of the battery contact, resulting in a short circuit in the battery, destroying the internal structure of the battery, and causing battery acid leakage.

Temperatura. Due to thermal expansion and contraction, the electrolyte and gas inside the battery will expand in a high-temperature environment. En este momento, if the sealing ring inside the battery is of poor quality, it is easy to leak the battery acid.

High temperature generally catalyzes chemical reactions, and the electrolyte decomposes and produces new substances, which can easily corrode the internal structure of the battery, increase the pressure inside the battery, and cause battery acid leakage.

Part 4: How to Deal with Battery Acid Leakage

When there is a battery acid leak, in order to ensure personal safety, immediately deal with it, in order to avoid the occurrence of chemical corrosion, flammable and explosive, gas poisoning and other health hazards such as the occurrence of the situation. In order to enable you to safely deal with battery acid leaks, this article compiles the steps and methods applicable to most battery acid leaks, como sigue:

Paso 1: Ensure the environmental safety of the leak site

The first time you find a battery acid leak, you should quickly move away from the leaking battery, avoid direct contact with the battery acid, so that your body is in a safe environment. If it is in a closed environment with no air circulation, try to ensure air circulation to avoid gas poisoning. If you are outdoors, you can avoid gas poisoning caused by battery acid by standing upwind. En este momento, if the battery is still in operation, to ensure that the environment is not a greater danger, immediately turn off the power to stop the battery operation.

Paso 2: Take protective measures

When dealing with leaking battery acid, be sure to do a good job of personal protection to avoid injury to personal health. When doing a good job of personal protection, you can start from the following points:

Limbs: make sure that the limbs are covered by clothes, hands and other key parts in direct contact with battery acid, you need to wear rubber gloves made of nitrile, such gloves can to a certain extent to prevent battery acid corrosion of the skin as well as damage to the skin by foreign objects.

Eyes: Eyes are very fragile, always wear goggles to prevent splashing into the eyes when handling battery acid.

Breathing: Some types of battery acid leaks may be accompanied by the evaporation of harmful gases, which can be prevented by wearing protective equipment such as masks and gas masks.

Paso 3: Handle battery acid contact with the skin (if it occurs)

If the battery acid contacts the skin, it should be immediately rinsed with plenty of clean water to quickly reduce the concentration of the battery acid and reduce damage to the skin. It should last for at least 15 minutos. Blindly using neutralizers will cause secondary damage to the skin. Al mismo tiempo, according to different battery types, further treatment is required (if redness, swelling, and pain are still present after treatment, please seek medical attention immediately):

Batería de plomo-ácido: The main component of the battery acid in lead-acid batteries is sulfuric acid, so it needs to be neutralized with alkaline substances. Common soaps in life are alkaline. You can use soap or baking soda water to gently wipe the skin and then rinse it clean.

Alkaline battery: The main component of the battery acid in alkaline batteries is potassium hydroxide, so it can be neutralized with acid. Citric acid or diluted white vinegar are both good choices. Just wipe it gently and then rinse it with clean water.

Lithium battery: The battery acid in lithium batteries is composed of organic solvents. The characteristics of organic solvents are low toxicity and short-term contact is harmless, so you only need to rinse it with plenty of clean water.

Paso 4: Isolate the battery

After ensuring the on-site environment and personal safety, remove the battery with battery acid leakage to prevent a larger accident. When contacting, be sure to bring protective tools. When removing, isolate the battery in a leak-proof plastic box or metal container, and be sure to keep away from flammable materials.

Paso 5: On-site cleaning

1. Small leakage

For a small amount of battery acid leakage, the more common method is to use absorbent materials, such as towels and paper towels, etc., to fully cover the leaked battery acid to avoid direct contact, and then handle the materials with battery acid.

2. Large leakage

Batería de plomo-ácido: En este momento, the main material in the battery acid is sulfuric acid, which can be neutralized by sprinkling baking soda. En este momento, foam will be generated. Wait until the foam is reduced before cleaning.

Alkaline battery: Potassium hydroxide in the battery acid can be neutralized by slowly pouring white vinegar and lemon juice. After neutralization, absorb the residual liquid on site and then clean it up.

Lithium battery: The organic solvent of a lithium battery cannot be in contact for a long time, which will cause harm to the human body, so it can be mixed with dry sand or cat litter, and then the mixture can be put into an explosion-proof container.

Paso 5: On-site cleaning
