Feature

Wide Operating Temperature Range
While the operating temperature range of the Standard is from −30 °C to 70 °C, the range of the Extended Temperature has been expanded from −40 °C to 85 °C. This type supports electronic components and IC of which operating temperature range is up to 85 °C 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 °C.
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.
