LR23 battery is a type of energy battery that is primarily used in electronic radio control systems such as keyless entry systems, home security systems, garage door controls, and Bluetooth headphones. An LR23 battery is cylindrical, smaller than an AAA battery, measuring 28.5 mm in length and 10.3 mm in diameter, with a typical weight of 8 grams. An LR23 battery is an 8-cell device with a nominal voltage of 12V. The higher voltage is needed for radio frequency transmitting and receiving devices than batteries. It has a capacity of about 55 mAh. LR23 batteries are constructed with 8 individual LR932 alkaline button cells enclosed in a case. The LR23 battery is similar to the N battery, which has a voltage of 1.5 V.
