Yes it does charge to 16 bars, however I've noticed on Canion that sometimes it stops at 98% instead of 100% on a Level 2 charge.
What degree of battery malfunction causes it to indicate less than 16 bars after fully charging ? A usable Ah capacity below a certain threshold ?
You say it is one of the criteria - is this for Citroen/Peugeot in the EU/UK, or for Mitsubishi in the US/EU/UK ? I don't suppose you happen to know all the official criteria that warranty battery pack replacements are based on ? I have even contacted Peugeot UK head office but cannot get any useful information out of them.
I suspect it's not "bad" enough yet to meet any criteria they may have, however the car turns 8 years old next June and I do 12k miles a year in it.
I'd have to check but as far as I know the cell voltage is balanced within 10mV after a full Level 2 charge. It's only after the battery has discharged below about 40% that the voltage of the weak cells starts to drop a lot faster than other cells, suggesting the weak cells have less usable capacity than the rest.
One other thing I forgot to mention is that rapid charging last summer always used to stop at exactly 82% reported by Canion or the Rapid charger. This summer, since the cell problems have appeared, rapid charges often stop anywhere between 74% and 80%, even though the car may have been charging for less than 20 minutes. I don't think stopping before 82% is normal rapid charging behaviour except in extreme cold where it takes long enough to hit the 30 minute rapid charge time limit.
