Batteries power nearly every aspect of our lives. From smartphones and laptops to cars and remote controls, batteries play a crucial role in keeping our devices and appliances running efficiently. However, when these batteries reach the end of their useful life, improper disposal can pose serious environmental and health risks.
We’ll walk you through the types of household batteries you’ll encounter, how to dispose of batteries safely, and who can help you get rid of old batteries.
It's essential to understand the different types of batteries and their composition, as each type requires specific handling.
Alkaline batteries are one of the most common batteries in households and businesses. They are typically non-rechargeable and offer a stable and reliable source of power. These batteries are available in various sizes, including AA, AAA, C, D, and 9V.
These batteries consist of zinc, manganese dioxide, and potassium hydroxide. Alkaline batteries are suitable for low-to moderate-power devices like:
While they provide decent energy storage, they are not cost-effective for high-drain devices or long-term use.
These small, disc-shaped batteries are designed for compact devices that require a long-lasting and stable power supply. Some may contain mercury, silver oxide, or lithium.
These batteries are found in watches, hearing aids, medical devices, calculators, and other small electronic devices. They are favored for their compact size and the ability to provide consistent power over extended periods.
Lead-acid batteries are among the oldest and most reliable rechargeable batteries. They are commonly used in automobiles and as backup power sources. They are known for delivering high bursts of energy and are cost-effective for high-current applications.
These batteries contain lead plates and sulfuric acid. A chemical reaction between the two components creates electricity.
Rechargeable batteries offer a more sustainable and economical alternative to disposable batteries. They can be recharged and reused multiple times, reducing waste and the need for frequent replacements.
These types of rechargeable batteries below, are found in electronics like laptops, smartphones, and power tools.
Improper battery disposal can have severe consequences for the environment and human health.
Batteries should never be thrown in the trash because of the hazards they pose. When they end up in landfills, they can leach harmful chemicals. For example, alkaline batteries can corrode and release zinc and manganese dioxide into the soil. Rechargeable batteries can release lithium, nickel, cadmium, and cobalt. Batteries of any type can contaminate water sources and potentially harm wildlife.
Burning batteries is no solution. Smoke from these batteries releases toxic fumes into the air, further contributing to pollution and respiratory issues.
Batteries can harm human health if they aren’t cared for properly. Alkaline batteries can leak potassium hydroxide, a caustic alkaline, which can cause irritation and burns. Rechargeable batteries can contain nickel-cadmium, which can pose health risks. Cobalt and nickel in rechargeable batteries can cause skin irritation and respiratory issues. Leaking lead-acid batteries can cause neurological damage, developmental issues, and kidney damage.
This is why batteries must be recycled or disposed of safely and responsibly.
You should also check locally for recycling practices and regulations. For example, California considers batteries hazardous waste. The state requires residents to take batteries to an authorized recycling center, a waste handling service equipped for the task, or a household hazardous waste facility. Disposing of any battery in the trash is against the law in California.
First, sort your batteries by type, especially if you’re disposing of them in collection boxes or bags. To prevent fires or short-circuiting, cover the terminals of each battery with non-conductive tape, such as electrical tape. Secure the batteries in small, separate containers.
If possible, use the remaining charge in rechargeable batteries before disposal. Be sure to inspect rechargeable batteries for leakage or damage. If you find any, pack those batteries separately.
Safely disposing of batteries is a responsibility we all share to protect the environment and our communities. By understanding the different types of batteries and following proper disposal methods, you can help minimize environmental pollution and potential health hazards.
