Feature

  • Wide Operating Temperature Range
    While the operating temperature range of the Standard is from -30 ºC to 70 ºC, the range of the Extended Temperature has been expanded from -40 ºC to 85 ºC. This type supports electronic components and IC of which operating temperature range is up to 85 ºC 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 85 ºC.
  • Maximum capacity with coin lithium battery*1
    The largest capacity "CR3677X" in the Extended Temperature has the largest capacity*1among 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.
