Batteries are commonly used in small electronic devices, such as TV remote controls, MP3 players, and digital cameras. Devices that draw higher currents but operate 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 designed to use AA batteries are being replaced by models that accept AAA batteries. An AAA battery measures 44.5 mm (1.75 in) long and 10.5 mm (0.41 in) in diameter. AAA alkaline batteries weigh about 11.5 grams each, while AAA lithium batteries weigh about 7.6 grams, and rechargeable (Ni-MH) batteries typically weigh between 14 and 15 grams. 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 between 900 and 1155 mAh (3240 to 4158 coulombs).
