r134a Might be battery wasn't calibrated for a while when it reported 93%.
Could be. On the mentioned P9P charging limit option is also used (not from the beginning, started to use maybe between 30-50 cycles, but automatic calibration never worked, it never charged to 100% without user intervention. For calibration limit option was disabled every 2 to 3 weeks for "manual" calibration but none of these ever changed the battery health status.
