Alkaline batteries are a type of single-use, disposable battery that provides reliable, long-lasting power for a variety of devices.

They use an alkaline electrolyte, typically potassium hydroxide, which helps to produce a higher energy output compared to traditional zinc-carbon batteries. Commonly used in everyday items like remote controls, flashlights, toys, and portable electronics, alkaline batteries are known for their consistent performance and longer shelf life. They are available in various sizes, including AA, AAA, C, D, and 9V, making them versatile for both household and commercial applications.
