Silver oxide button battery has the advantages of smooth discharge, high energy to weight ratio, etc. It is generally used as a button battery, or used in some specific applications that require higher requirements and can afford the high cost, such as some torpedoes or submarines. For more information about the silver oxide button battery, please read the following words.

How does the silver oxide button battery work?
Silver oxide button battery is self-discharging even when not in use. Humidity and high temperature will increase the self-discharge of the battery, so store it in a low temperature and dry condition. The current output of silver oxide button battery will become very weak when the battery is under 0 ℃, and the quartz watches with lights and alarms and digital display windows will be affected.
Unlike ordinary dry cell batteries, the discharge curve of silver oxide button battery is very flat, it does not gradually decrease in voltage with use like dry cell batteries (see photo), which is of course good for maintaining the accuracy of quartz watches. But it also brings a problem, that is, you can't measure the voltage to determine how much battery capacity is left, the nominal voltage of silver oxide battery is basically 1.55V, and this voltage will be maintained until the end of the battery life.
Once the silver oxide button battery voltage starts to drop, its service life will be up immediately, so in order to avoid affecting the normal wearing of quartz watches, many quartz watches are set with a battery voltage warning function, which is indicated by the second hand pausing for 4 seconds and then jumping sharply for 4 consecutive seconds, once this phenomenon occurs, the quartz watch can still run for about 10 days. Remind you to replace the battery immediately. This function is also called "E.O.L", but quartz watches without a central second hand do not have this function.
Silver oxide button battery is an alkaline battery with silver oxide as the positive electrode active substance and zinc as the negative electrode active substance. Ag2O + H2O → Zn(OH)2 + Ag when charging: Zn(OH)2 + Ag → Zn + AgO + H2O or Zn(OH)2 + Ag → Zn + Ag2O + H2O The fuel cell is a power generation device that converts the chemical energy present in the fuel and oxidizer directly into electrical energy.
It directly converts the chemical energy of the fuel into electrical energy without going through the combustion process in between.
