A23 battery

The A23 battery is a dry cell-type battery mainly used in small electronic keychain radio devices, such as keyless vehicle entry systems, home security systems, garage door openers, and Bluetooth headsets.[1] This battery type may also be referred to as 23AE, GP23A, V23GA,[2] LRV08,[3] 8LR932,[4] 8LR23, MN21, L1028 or ANSI-1181A.

An A23 battery is cylindrical and somewhat shorter than a AAA battery, measuring 28.5 mm long and 10.3 mm 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.[1]

A23 batteries are constructed of eight individual LR932 alkaline button cells enclosed in a wrapper.

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% .
