How to Dispose of Leaking Batteries

Disposing of leaking batteries can be challenging, especially if you don’t know the right way to do it. The Environmental Protection Agency (EPA) warns that when not properly handled, batteries may pose a hazard to human health or the environment due to their metal content, including mercury, lead, cadmium, nickel, and silver.

To properly get rid of leaking batteries start by wrapping the battery in a paper towel to avoid contact with the skin. Place the battery in a plastic bag and tape it shut, then drop it off at a designated local recycling center.

If a recycling center is not available, contact your local waste management authority for advice on proper battery disposal. Also, don’t forget to clean up the cleaning acid but wear protective gear while doing so.

What Is Battery Acid?

Battery acid is the common name for the electrolyte solution used in lead-acid batteries, such as those found in automobiles. The electrolyte solution is made up of sulfuric acid and water and is typically around 35% sulfuric acid and 65% water (by weight). It is highly corrosive and has a pH of less than 1.

Battery acid is highly eroding and can cause serious injury or death if it comes in contact with skin, eyes, or any part of the body. It is important to wear safety glasses and protective clothing when handling battery acid and to avoid contact with skin and eyes. Additionally, it should always be stored in an approved, sealed acid container.

Why Do Battery Leak?

Battery leaks occur when the active material inside the battery reacts with the electrolyte, producing gas bubbles that increase the pressure inside the battery. This pressure can cause the battery to rupture and leak its contents, which can be corrosive. However other common causes of battery leaks are explained below:

  1. Overcharging: If a battery is overcharged, it can cause electrolytes to escape through the seals and vents, resulting in a leak. This typically occurs when batteries are left on a charger for too long, or when the charger is faulty.
  2. Old Age: Batteries naturally suffer from “self-discharge” over time and can eventually become unable to hold a charge. As the battery gets older, the internal components can become weaker and start to deteriorate, leading to electrolyte leaking from the cell.
  3. Temperature: Temperature fluctuations can also cause battery leakage. High temperatures can cause the electrolyte inside the battery to evaporate, while low temperatures can cause the electrolyte to freeze and expand, resulting in the seals being forced open.
  4. Damaged Seals: Cracked or damaged seals on battery cells can lead to a hazardous battery leak. This can occur due to accidental physical damage like dropping the battery, or even due to flaws in the manufacturing process.
  5. Overuse: When a battery is overused, it can become exhausted and start to seep. This is especially the case with rechargeable batteries, for the more they are used, the quicker their expiration.

How to Avoid Batteries Leaking?

Electronic devices are often powered by batteries, but when these batteries start to leak, it can lead to a world of trouble. To help prevent this, it’s wise to take certain precautions as discussed below:

  1. Choose the Right Battery: Look for batteries that are designed for the specific device you are using.
  2. Store Batteries Properly: Store batteries in a cool, dry place. Excessive heat can cause batteries to degrade more quickly and can lead to leakage.
  3. Don’t Mix Battery Types: Don’t mix battery types, such as alkaline and rechargeable, in the same device.
  4. Remove Batteries When Not in Use: Remove batteries from devices that are not in use for extended periods of time.
  5. Don’t Overcharge: Don’t leave rechargeable batteries in a charger for too long, as this can cause them to overheat and leak.
  6. Inspect Batteries Regularly: Check your batteries regularly to make sure they are not leaking or bulging.
  7. Check Expiry Date: Check the expiration date of the batteries before use. Batteries can go bad over time, and using expired batteries can lead to leakage.

How to Store Leaked Batteries?

It’s essential to safeguard against potential fire or health issues by properly storing any leaked batteries. Here are some ways to do so:

  1. Isolation: Isolation is a good way to store leaking batteries as it prevents contact between the hazardous material and the surrounding environment. This can be done by placing the batteries in containers that are sealed and equipped with proper ventilation.
  2. Neutralization: The process of Neutralization is invaluable in combating the effects of overly acidic liquids. By adding a neutralizing agent to a leaking battery, the acidity can be brought down to a safe level, safeguarding the environment from any potential contamination.
  3. Encapsulation: Encapsulation is the process of covering the leaking battery with a protective coating, such as a plastic or rubber material, to prevent contact between the hazardous material and the environment.
  4. Cooling: Leaked batteries should be kept in a cool place. If the temperature is too hot, then the battery can overheat and potentially cause a fire.
