What is the potential consequence of not storing old batteries properly?

The potential consequence of not storing old batteries properly is contamination of soil and water. Batteries, particularly lead-acid batteries, contain harmful materials such as lead, sulfuric acid, and other heavy metals. When batteries are not stored in a safe and secure manner, these substances can leak out, especially if the batteries become damaged or corroded. This leakage can lead to soil contamination, posing risks to plant life, wildlife, and ultimately human health. Additionally, if the contaminants reach waterways, they can cause serious water pollution issues, affecting aquatic ecosystems and drinking water supplies. Proper storage and disposal of batteries are essential to prevent these harmful environmental impacts.
