• Lightweight, High Voltage and High Energy Density

The battery voltage is 3V, almost double that of normal alkaline or

manganese batteries. This means that the number of batteries

required for equipment can be halved for maximum space saving

and weight reduction.

• Excellent Discharge Characteristics

Voltage characteristics remain stable even for a long period of

discharge, greatly improving the reliability of equipment that uses

the battery. Such equipment is also maintenance-free (battery

replacement is seldom required).

• Wide Operating Temperature Range

While the operating temperature range of the Standard is from -

30ºC to 70ºC, the range of the Extended Temperature has been

expanded from -40ºC to 85ºC. This type supports electronic

components and IC of which operating temperature range is up to

85ºC in many cases. Also, the excellent storage characteristics

minimize the voltage drop compared with the Standard even when

the Extended Temperature is stored for 100 days or more at 85ºC.

• Maximum capacity with coin lithium battery*1

The largest capacity CR3677X*2 in the Extended Temperature

has the largest capacity*1 among coin lithium batteries. This

model has a nominal capacity higher than the CR123A battery and

CR2 battery, and contributes to downsizing and slimming of

electronic devices.

*2 Shipment of mass-produced CR3677X is scheduled to start at

the end of 2019

• Excellent Leakage Resistance

The newly developed battery construction and electrolyte ensure

maximum leakage resistance over a long span of time.

• Excellent Long-Term Reliability

Carefully selected active materials are used for the active material

as well as for the electrolyte. These materials are sealed by

Murata's innovative technology to minimize battery self-discharge.

The annual self-discharge rate at room temperature and normal

humidity is less than 1 of the nominal capacity.

• UL Approved Parts

Murata's Coin Manganese Dioxide Lithium Batteries are approved
