As lithium coin battery ingestion by babies or toddlers is a serious topic, it is important to learn about the… Regarding chemistry, A23 belongs to the category of non-rechargeable alkaline batteries. This battery type often appears in small electronic devices such as Bluetooth headsets, video game controllers, cameras, keyless vehicle entry systems, etc.
Given this common ground, most battery compartments made for N-cells can accommodate the A23 with ease. In comparison, only some, not all, A23 compartments work with the E90. The A23 and N-cell (E90) batteries possess relatively similar physical dimensions. The former is 10.3 x 28.5 mm, while the latter is 12 x 30.2 mm. Another similarity is that both belong to the wide category of alkaline batteries. 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. Overview [of special battery types] - VARTA Consumer Batteries". VARTA Consumer Batteries . Retrieved 2017-09-16.
