What should I do with used batteries?

Waste batteries should be disposed of.

1. At present, there are two main types, one is the lead-acid battery with electrolyte, and the other is the maintenance-free battery. The service life of an automobile battery not only depends on the structure and quality of the battery, but also is closely related to its operation and maintenance. Generally, the service life of automobile batteries is about 2 years, and if properly maintained, it can reach 3 to 4 years.

It is very necessary to maintain the battery once during the change of seasons.

2. The maintenance-free battery does not need to add distilled water and adjust the concentration of the electrolyte, it is fully sealed, and there will generally be no electrolyte overflow to the surface of the battery. Its maintenance is very simple, mainly to check whether there is any leakage, clean the surface dirt, treat the oxide of the positive and negative pole piles, fasten the clips of the two pole piles and observe the color of the battery eye. The color of the electric eye is green, which means that the battery is sufficient; Black is insufficient power and needs to be recharged; Gray or light yellow means that the electrolyte is insufficient, because the maintenance-free battery cannot be filled, the battery should be replaced immediately.

3. The maintenance of lead-acid battery is more troublesome, in addition to the maintenance items of the maintenance-free battery mentioned above, it is also necessary to pay attention to the following two aspects: one is to check and adjust the height and concentration of the electrolyte, the height of the electrolyte should be between the highest (max) and the smallest (min), too low will reduce the capacity of the battery, so that the plate produces vulcanization, too high will overflow to the surface of the battery to corrode the pole pile, wire and body. The concentration of electrolyte has a great impact on the working condition of the battery, the sulfuric acid concentration of the electrolyte in our Northeast winter should be adjusted to grams, and the concentration measurement and adjustment must be carried out under the condition that the battery is fully charged; The second is to clean and dredge the exhaust pipe, keep the exhaust pipe well ventilated, and discharge the exhaust gas generated during the charging process in time, otherwise it will lead to the overflow of the electrolyte from the liquid filling hole, and even lead to the battery in serious cases.

4. The harm of waste batteries: The mercury in the batteries discarded in nature will slowly overflow from the batteries, enter the soil or water source, and then enter the human body through crops, damaging the human kidneys. Under the action of microorganisms, inorganic mercury can be converted into methylmercury, which gathers in the body of fish, and after people eat this fish, methylmercury will enter human brain cells, causing serious damage to the human nervous system, and the serious ones will go crazy and die.

The famous Japanese Minamata disease is caused by methylmercury. Cadmium exudates and pollutes land and water, and eventually enters the human body to damage the liver and kidneys, and can also cause bone weakness, and in severe cases, bone deformation. The leakage of acid and heavy metal lead contained in automobile waste batteries into nature can cause soil and water pollution, and ultimately cause harm to people.

What would you do with a used battery that has no power?

Waste lead-acid storage.

Battery** utilization process:

1. Waste lead-acid batteries are transported to the smelter warehouse by special environmental protection vehicles;

2. Pour the electrolyte of the waste lead-acid battery into the sedimentation tank for drug treatment;

3. Disassemble the waste lead-acid battery and send the shell to the plastic factory for professional treatment;

4. Sort the separator of the waste lead-acid battery and send it to a professional factory for processing;

5. Send the sorted waste plates to a large reverberatory furnace for smelting, make lead ingots, and recycle them;

6. The wastewater generated in the smelting process flows into the sedimentation tank and is treated with the electrolyte;

7. The waste residue generated in the smelting process shall be sent to a professional ironmaking plant for disposal;

8. The waste smoke generated in the smelting process will be safely discharged after being treated by the bag dust removal device, and the environmental protection process of the waste lead-acid battery will be completed. Waste batteries contain a large number of renewable heavy metals and acids, such as lead-acid batteries, the first utilization of lead-acid batteries is mainly based on waste lead recycling, including the use of waste acid and plastic shells. At present, the metal utilization rate of lead-acid batteries for domestic waste cars has reached about 80 85%.

According to industry estimates, according to the calculation of processing 100,000 waste batteries per day, after removing various expenses, it can make a profit of about 20,000 yuan; With 7 billion batteries and a utilization rate of 50%, the annual profit can reach more than 600 million yuan. It can be seen that the implementation of large-scale operation in this field can create benefits.

Do not throw it away casually, so as not to pollute the environment and cause harm to the human body. The disposal of waste dry batteries should pay attention to two main points: one is to prevent environmental pollution; The second is the use of **.

The disposal methods of waste dry batteries are: 1 **Utilization: For waste dry batteries, it can be used, but we must pay attention to safety to prevent accidents, so as not to cause environmental pollution.

2. Landfill: For the landfill of waste dry batteries, attention should be paid to choosing a reasonable place to prevent pollution of groundwater and soil, so as not to cause environmental pollution and damage. 3 Compost:

For the composting of waste dry batteries, a suitable place should be selected, and attention should be paid to prevent environmental pollution, so as not to cause environmental pollution and damage. 4. Incineration: For the incineration of waste dry batteries, environmental pollution should be prevented, so as not to cause environmental pollution and damage.
