Ultralife Lithium Manganese Dioxide cells have some of the highest energy density and performance characteristics of all Lithium based battery chemistries. Lithium Manganese Dioxide cells offer excellent temperature characteristics, a flat discharge curve, and a hermetically sealed nickel plated steel container for long term shelf life. Lithium Manganese Dioxide cells do not form a passivation layer, so after long storage periods without use can deliver high current immediately. This makes our Lithium Manganese Dioxide cells the perfect choice for applications where high currents are required after long periods of inactivity.
