Young people are taught to recycle everything, lest it become part of a floating island of garbage in the ocean.

Good for you if you recycle your plastic bottles and metal cans.

But what about your car battery? Auto batteries last for 5 years, 10 years tops. By the time you reach age 40, you may have gone through 5 or 6 of them.

Car batteries are a particular concern in landfills because:

  • They contain toxic chemicals like lead and sulfuric acid.
  • They can leak these toxins into the soil and groundwater.
  • They can release harmful gases into the atmosphere if incinerated.
  • They take up space and contribute to landfill overcrowding.

With so many car batteries being disposed of yearly, proper recycling is crucial to protect the environment and human health. But how exactly are car batteries recycled, and why is there so much fuss about it? Let’s find out.

Symptoms of a Failing Car Battery

  • The engine cranks more slowly than usual or takes longer to start.
  • A battery warning light on the dashboard comes on.
  • Your headlights are dimmer than usual.
  • Electrical components like power windows, radio, or air conditioning malfunction.
  • Visible corrosion on the battery terminals and cables.
  • A swollen or bloated battery case.
  • Battery age (more than 3–5 years old).

If you notice one or more of these signs, it may be time to purchase a new battery and recycle your old one.

How Are Car Batteries Recycled?

Recycling a car battery involves several steps to extract and reuse its components safely.

1. Collection

A spent car battery should be taken to an authorized collection center, recycling center, battery dealership, or mechanic who will dispose of it properly.

2. Draining

The battery is drained of any remaining acid or electrolyte solution. The recycler tilts the battery and allows the liquid to flow into a special holding tank.

3. Breaking Down

Next, the plastic casing and lead plates are crushed or shredded to separate them from each other. The polypropylene (plastic) is sent for recycling, while the lead plates are used for new batteries.

4. Neutralization

The battery’s acid is neutralized through a chemical process or by adding an alkaline substance like baking soda, making it safe for disposal.

5. Filtration

Any remaining debris or impurities are filtered out of the electrolyte solution, which can be reused in new batteries or sold to other industries.

6. Smelting

The lead plates and terminals are melted down through a process called smelting. The impurities are burned off, and the pure lead can go toward new batteries or other products.

7. Recycling

The final step involves recycling all the extracted materials for reuse in various industries. This includes polypropylene plastic, lead, and other metals like copper and steel.

Why Is Car Battery Recycling Important?

Now that we know how car batteries are recycled, let’s explore why we should keep them out of landfills or incinerators.

1. Protecting the Environment

Car battery recycling prevents toxic chemicals from leaching into the soil, polluting water sources, and potentially harming wildlife and human health.

2. Reducing Landfill Waste

Recycling reduces the amount of waste in landfills and contributes to environmental problems like greenhouse gas emissions.

3. Conserving Natural Resources

Recycling car batteries allows for the extraction of valuable materials like lead, lessening the need for mining and conserving natural resources.

4. Economic Benefits

Recycling also has economic benefits, such as creating jobs in the recycling industry and lowering manufacturing costs.
