These AA alkaline batteries, with the popular designation LR6, offer a reliable and affordable power source for a wide range of devices. Their long life and mass availability make them an ideal choice for torches, toys, and other appliances that require a constant power supply.
Since their standardisation in 1947, AA batteries have evolved, incorporating different technologies such as lithium, which provide a greater charging capacity. Their standard size, with a length of 51mm and a diameter of 14mm, makes them compatible with a wide variety of devices. Rechargeable batteries, such as NiMH, offer a sustainable alternative, albeit with a slightly lower voltage than alkaline batteries.
