Battery format Left to right: AA, AAA, AAAA, E90 and A23 batteries An open A23 battery showing the LR932 cells with an intact battery The A23 battery is close in size to the N battery, which has a voltage of 1.25 V to 1.5 V. It is also similar to the A27 battery, which has the same 12 V nominal voltage and almost the same length but is smaller in diameter by about 20%. [5] See also [ edit ] A23 batteries are constructed of eight individual LR932 alkaline button cells enclosed in a wrapper. The A23 battery (also referred to as 23AE, GP23A, V23GA, [1] LRV08, [2] 8LR932, [3] 8LR23, MN21, L1028 or ANSI-1181A) is a dry battery consisting of eight LR932 cells, with a nominal voltage of 12 V. An A23 battery is cylindrical and approximately two-thirds the length of an AAA battery, measuring 28.2mm long and 10.0mm in diameter, with a typical weight of 8 grams. An A23 battery is an 8- cell device with a nominal voltage of 12 V. The higher voltage is necessary for the radio frequency- transmitting and receiving devices which A23 batteries often power. It has a capacity of around 55 mAh. [4]
