4 AAA BATTERIES - MAXELL

Batteries are commonly used in small electronic devices, such as TV remote controls, MP3 players and digital cameras. Devices that operate at the same voltage but require higher currents 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 is 44.5 mm long and 10.5 mm in diameter. AAA alkaline batteries weigh around 11.5 grams each, while AAA lithium batteries weigh around 7.6 grams and rechargeable batteries (Ni-MH) generally weigh between 14 and 15 grams. The nominal voltage of AAA alkaline and lithium batteries is 1.5 V, while that of Ni-MH or NiCd batteries is 1.2 V. The capacity of AAA alkaline batteries is normally 900 to 1155 mAh (3240 to 4158 coulombs).
