How CR1216 Battery Works

Battery Chemistry Explained: CR1216 is a Lithium Manganese Dioxide (LiMnO2) battery that utilizes lithium to react with manganese dioxide to generate electrical energy.

How lithium batteries generate electricity: Lithium batteries release electrical energy through redox reactions between the positive and negative electrodes by moving lithium ions through the electrolyte.

Battery Discharge Curve: With use, the voltage of the battery gradually decreases, usually when it is close to the battery is fully discharged, the voltage will drop rapidly. the standard voltage of CR1216 battery is 3V, the voltage will slowly decrease during the discharge process, until the device stops working when it is close to 2V.
