CR (Coin Type Lithium Manganese Dioxide Battery)

Features

Stable operating voltage under long-term low load discharge for Memory and RTC backup

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 high and low temperatures.

Superior leakage resistance and excellent storage characteristics

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

Warnings

• Nominal capacity indicates duration until the voltage drops down to 2.0V when discharged at a nominal discharge current at 20 deg. C.
• When using these batteries at temperatures beyond the range of 0 to +40 deg. C, please consult Maxell in advance for conditions of use.
• Dimensions and weight are for the battery itself, but may vary depending on the shape of terminals or other factors.

• Data and dimensions are not guaranteed. For further details, please contact us at your nearest Maxell office.

Construction

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.

Safety precautions

If misused, this battery may deform, leak (the liquid inside the battery may leak to the outside), generate heat, explode, or ignite.
Since such misuse may cause injury or equipment failure, please be sure to read and observe [Warnings and Cautions].
