Recalibrating the Battery
Recalibrating the Battery
Depending on the way the unit is used, after a while, the charge status icon
may no longer correspond to the actual power level of the battery (for
example, the battery level icon indicates that power level is sufficient, but
unit turns off because battery is too weak). A complete calibration cycle
will be necessary.
You can perform a recalibration with the battery calibration utility:

The utility will charge the battery until it is full.

It will then discharge the battery completely.

You will have to let the battery recharge completely.
The whole calibration process can take several hours. You can stop the
process at any time, but the battery will still need calibration and the
battery will not necessarily be full (depending on the moment at which you
stop the process).
When a calibration step is underway, the LED preceding the step name
appears in yellow. When a step is complete, the LED turns to green.

MPORTANT
When the estimate offset value (displayed in the battery calibration
application) is of 10 % or more, EXFO recommends that you
recalibrate the battery.
