An alkaline battery is the primary type of battery. It produces energy through a chemical reaction between manganese dioxide and zinc metal. The reaction is called an electrochemical reaction. The energy is then stored in the battery, allowing it to ... More
Alkaline AAA/AM4 batteries are standard chemistry types and have a 1.5 V nominal voltage. They have a capacity of 850-1200 mAh, high energy density, and a long shelf life. In many cases, these batteries can last up to ten years or more. Most alkaline... More
The alkaline dry battery is a primary energy source. It produces energy through a reaction of zinc metal and manganese dioxide. This type of battery can be used in a variety of applications, including emergency lighting, radios, portable speakers, an... More
The zinc/manganese dioxide combination in alkaline dry batteries is composed of zinc powder and manganese dioxide. The zinc powder provides more surface area for chemical reactions and lowers the internal resistance of the battery. The manganese diox... More
