What is an Alkaline Battery?
The world’s energy needs are ever greater and more varied as time goes on. One source of energy has developed as a convenient way to power electronic devices, and that is the alkaline battery. Batteries are essentially small containers that hold chemicals which react to produce electricity. The alkaline battery is the most common and versatile type of battery used, and it gets its name because of the alkaline electrolyte potassium chloride, which is one of the chemicals it contains. Each alkaline battery has two ends, or terminals — a positive and a negative terminal. Inside the battery, a chemical reaction produces electrons, which gather at the negative terminal of the battery. However, unless the negative terminal is connected to the positive terminal, the chemical reaction stops and no more electricity is produced. This is the reason that an alkaline battery can sit in a drawer or on a shelf for a long time and still have plenty of power when it is needed. If it is not used, the b
Different chemistry. The “regular” carbon-zinc battery uses an acidic electrolyte, while the alkaline one uses… alkaline. Alkaline batteries have a greater capacity per volume than regular carbon-zinc, so they last longer. They also have lower internal resistance so they perform better in pulsed applications, like cameras and other high-drain loads.
