| Product Safety Data Sheet |
|
|
|
| |
The cylindrical lithium manganese dioxide battery (CR battery) features high capacity and excellent load characteristics due to Maxell’s unique winding method and improved electrical-conductivity structures. Because of its high-reliability, this battery is ideal for industrial use in, for example, security equipment and the power source of electronic meters. |
| |
The cylindrical lithium manganese dioxide battery uses manganese dioxide (MnO2) as its positive active material and lithium (Li) as its negative active material. |

High capacity batteries |
| |
Maxell’s unique winding method and effective utilization of positive and negative electrodes realize a high capacity |
| • |
Low self-discharge rate and long battery life |
| |
A laser seal structure ensures air tightness. Minimized electrode surface areas reduce the self-discharge rate. |
| • |
Superior storage 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. |
