An alkaline battery AAA/AM4 is a type of small, cylindrical primary (non-rechargeable) battery. The "AAA" in the name refers to the physical size of the battery, which is one of the smallest sizes commonly used in consumer electronic devices. The "AM4" is a standard name for the battery, it's also known as "MN2400" and "LR03".
These batteries are used in a wide range of portable electronic devices, including remote controls, portable radios, flashlights, and digital cameras. They are known for their long shelf life, high energy density, and low cost. Alkaline batteries are made with a zinc anode, a manganese dioxide cathode, and a potassium hydroxide electrolyte. They have a voltage of 1.5V, and deliver a relatively consistent voltage over their useful life.
Alkaline battery AAA/AM4 are used in a wide range of portable electronic devices, including:
Remote controls: Alkaline batteries are commonly used in remote controls for televisions, DVD players, and other consumer electronics.
