Hi Graham, BEfore the discharge starts and the chatter begins, the battery will charge to full capacity. It's best to start the whole process when the battery level is below 90 percent and below 80 is better. If you start it with the battery already charged close to full capacity, the unit will trickle charge and it can take a very very long time to reach a full charge.
Once the battery has reached full charge it will start the discharge part of the cycle and start to chatter. Once the battery has discharged, it will charge again without chatter. Then, the calibration process should be complete.
