Product Information


The coin type lithium manganese dioxide battery (CR battery) is a small, lightweight battery with an operating voltage of 3V and the ability to operate over a wide temperature range. It has a wide range of applications, both for powering devices such as wristwatches and electronic calculators and can be used in all types of electronic devices mainly as memory and RTC backup.


•Optimum for Memory and RTC Backup (Fig.1)
Displays long-term stable operating voltage at low load discharge. 

•High 3 volt energy density 
High energy density. At 3 volts (nominal voltage), it has about twice the voltage of 
alkaline button batteries and silver oxide batteries. 

•Stable discharge characteristics through low internal resistance and high operating voltage 
Employs highly conductive electrolyte, lowering internal resistance and providing stable operating 
voltage. This allows stable power to be obtained, with little change in operating voltage at room 
temperature as well as high and low temperatures. 

•Superior leakage resistance and excellent storage characteristics (Fig.2) 
Employs a leak-resistant organic electrolyte, giving it better leakage resistance than battery types 
using alkaline electrolytes. Furthermore, the high degree of seal of the seal structure and application 
of sealant keep self-discharge to about 1% per year. 

•Superior high rate discarge characteristics (Fig.3)


Principle and Reactions

The coin type lithium manganese dioxide battery uses manganese dioxide (MnO2) as its positive active material, lithium (Li) as its negative active material, and an organic electrolyte.
