AAA batteries are commonly used in small electronic devices such as TV remote controls, MP3 players, and digital cameras. Devices that require higher currents while operating at the same voltage use larger AA batteries. AA batteries have three times the capacity of AAA batteries. However, with the increasing efficiency and miniaturization of modern electronics, many products that were designed to use AA batteries are being replaced by models that accept AAA batteries. An AAA battery measures 44.5 mm (1.7 in) long and 10.5 mm (0.4 in) in diameter. Alkaline AAA batteries weigh about 11.5 grams (0.4 ounces) each, while lithium AAA batteries weigh about 7.6 grams (0.2 ounces) and rechargeable (Ni-MH) batteries typically weigh between 14 and 15 grams (0.4 and 0.6 ounces). The nominal voltage of AAA alkaline and lithium batteries is 1.5V, while Ni-MH or NiCd batteries are 1.2V. The capacity of AAA alkaline batteries is typically 900-1155mAh (3240-4158 coulombs).
