Replace the ST6140 Battery and the "Ready-to-remove" LED steady blue
the CAM report "the battery near expiration" and the fault LED is light. So I have replaced all batteries of controller A & B according to the Service Advisor.
Then there is not any critial faults in the CAM and the fault led is off after the battery is charged. But the battery "Ready-to-remove" LED steady blue.
How could I work out the issue ?
