Maxell Cylindrical CR Type Lithium Manganese Dioxide Battery

The cylindrical type lithium manganese dioxide battery uses manganese dioxide (MnO2) as its positive active material and lithium (Li) as its negative active material.


Maxell’s cylindrical type lithium manganese dioxide battery realizes stable discharge characteristics with its original sealing structure, improved electrical-conductivity structure, and negative electrode material. This battery’s long-term reliability makes it ideal for use as a power source in industrial applications such as IoT devices and smart meters (e.g. gas, water, electricity). Battery packs can also be produced to meet special customer requirements. For details, please contact your nearest Maxell dealer or distributor.

Battery Reactions
Positive reaction :MnO2+Li++e- → MnOOLi
Negative reaction :Li → Li++e-
Total reaction :MnO2+Li → MnOOLi




Maxell was formed in 1960, when a dry cell manufacturing plant was created at the company's headquarters in Ibaraki, Osaka. In 1961, Maxell Electric Industrial Company, Limited was created out of the dry battery and magnetic tape divisions of Nitto Electric Industrial Company, Limited (now Nitto Denko Corporation).

On March 18, 2014, the company was listed on the First Section of the Tokyo Stock Exchange. In 2013, Maxell, Ltd. acquired Hitachi Consumer Electronics, Co., Ltd.’s projector design, development and manufacturing assets and resources. On October 1, 2019, Maxell Corporation of America announced it would assume responsibility for all operations related to both Hitachi- brand and Maxell-brand projector products and accessories in the North American market.


  • High energy density
    High energy density has been achieved by optimizing the filling rate of the material by means of a unique electrode structure.
  • Long-term reliability lasting more than 10 years*
    The employment of a heat-resistant gasket and a laser-seal structure prevents water intrusion and electrolyte evaporation, ensuring long-term reliability that lasts more than 10 years*. The self-discharge rate is about 0.5% per year.
  • Stable discharge characteristics
    The original negative electrode material maintains low internal resistance even at high depths of discharge and ensures stable discharge.
  • Superior low-temperature characteristics
  • High safety due to internal short-circuit prevention structure


  • Smart meters (e.g. gas, water, electricity)
  • IoT devices
  • Communication devices (e.g. 3G, LTE, LPWA)
  • In-vehicle devices
  • Security devices
  • Memory backup power
