Silver oxide battery used to power a quartz watch movement; battery is marked as containing no mercury Until 2004, all silver oxide batteries contained up to 0.2% mercury , incorporated into the zinc anode to inhibit corrosion from the alkaline environment. [ 12 ]
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%.
