I'm in process of buying a PHEV 2016 - waiting loan approval - and asked the authorized dealer (Mekenkamp - Bunnik, thanks @Jaapv for recommendation) to send me a "Battery State of Healthy" report.
He sent me the document bellow, but the only think related to the battery is its current capacity. I was expecting some more detailed information on the battery, but since I never saw one, I have no idea how it looks like.
It says the battery current capacity is 32,9A. What is the original capacity of this battery, in mAh (I know it is 12kWh).
