Discharge time as function of continuous operating current:
Operating temperature 23°C, Cut off voltage 2V
Example for calculation
Given:
- current drain 10µA
- expected discharge time 5 years
Selection result: - CR2450N
Remarks: This chart does not consider:
•
The voltage drop in case of pulse load applications
•
The available capacity at divergent operating temperatures. Please consult the specific diagram "Cell
capacity at various loads"
•
The loss due to self discharge
