OK. Although I got my car back with all 12 capacity bars and am reading 10% higher gid counts for an 80% charge (6% higher for a 100% charge), I have established that there is no difference in my battery capacity. In the graph below, I plot the battery voltage versus energy from the wall for three turtle to 100% charge logs. One last November, one just before the service and one just after. You can see that both the before and after service plots are almost identical (despite the charge afterward ending with higher gid count). I actually did two turtle to 100 tests this week just to make sure the first wasn't an anomaly and they both had the same result. So, no cells got replaced - looks like they may have recalibrated what a gids is but the battery performance is the same. To try to avoid overloading this thread any more, I created a separate thread to discuss the implications of variable gid:
