Maxell's cylindrical type lithium manganese dioxide battery features Maxell's unique sealing structure and an improved electrical-conductivity structure, and also uses a lithium-aluminum alloy as its negative electrode material to enable stable discharge. This battery's high reliability makes it ideal for use as a power source in industrial applications such as security devices and electronic meters. Assembled batteries can also be produced to meet special customer requirements. For details, please contact your nearest Maxell dealer or distributor.
•Long-term reliability of 10 years*
The employment of a heat-resistant gasket and a laser-seal structure ensures the battery is airtight.
Electrolyte leakage through evaporation and the impact of humidity have been minimized, while
self-discharge has been reduced and internal resistance increased.
•Stable discharge characteristics
Proprietary lithium-aluminum alloy used as the negative electrode material maintains low internal
resistance even at high depths of discharge and ensures stable discharge.
•Superior low-temperature characteristics
The optimization of positive materials and employment of a high-reliability sealing structure
stabilize pulse discharge characteristics over a wide usable temperature range after long time
storage or discharge.
•High safety due to internal short-circuit prevention structure

Maxell Cylindrical Type CR (lithium manganese dioxide) batteries are available only for equipment manufacturers as a built-in part. Therefore, Maxell does not supply these batteries for replacement directly to users of equipment with these batteries. When built-in Cylindrical Type CR batteries need to be replaced, please contact your equipment manufacturer. If you are planning to use Maxell Cylindrical Type CR batteries in your equipment as a built-in part, please contact Maxell.
Principle and Reactions
The cylindrical type lithium manganese dioxide battery uses manganese dioxide (MnO2) as its positive active material and lithium (Li) as its negative active material.
|Positive reaction ：
||MnO2+Li++e- -> MnOOLi
|Negative reaction ：
||Li -> Li++e-
|Total reaction ：
||MnO2+Li -> MnOOLi
