IMA Battery diagnosis using discharge-recharge method
 

I recently tested my IMA battery with scan tool when I parked a car after long trip in my driveway.
I let car sit with depressed brake pedal and in "D" position.
The car discharged IMA battery to keep AC and other accessories running.
Then ICE kicked in and recharged IMA battery to a safe level.
The discharge time was about 7 minutes with battery current = 3 Amps while recharge time was 2.5 minutes with battery current =5 Amps.
Do I have a chance to estimate a real battery capacity from this chart?
