Single-use batteries, also known as disposable batteries, are designed to be used until they run out of power and then discarded. Common types include AA, AAA, C, D, and 9V batteries, which are often found in household items like remote controls, toys, and flashlights. They are convenient because they do not require recharging and are readily available in stores. These batteries typically use chemical reactions to generate electricity, with common chemistries including alkaline and lithium. While they are easy to use, single-use batteries contribute to environmental waste, leading to concerns about proper disposal and recycling options to minimize their impact on the planet.
