Just finished getting a dealer battery calibration done.
Took a little longer than expected as it seems the older models (2009~2011?) require the process to be carried out manually.
The result is very interesting though. A very poor SoH of 54.583% with cells at 26.2 Ah (OBDZero shows as even worse: SoH @ 46%, cells at 23 Ah).
My RR at 100% has dropped to a measly 62km (!!), but
on the way home I noticed that both the battery gauge/RR gauge do not seem to change so unpredictably as before. Before the calibration my battery gauge behaved like so:
16 bars ~ 13 bars: Loose these bars after just 5~6 km
13 bars ~ 8 bars: RR would suddenly drop around 10 km after parking up and starting again
8 bars ~ 3 bars: Relatively stable
3 bars and less: Chance the car will stop suddenly, so I don't dare go this low!
Will have to see what happens at a lower SoC...
