To see at what rate your battery is charging at, open the INPA program>> E90>>ENGINE>>MSD80>> Status(F5)>>PM-IBS>>
PM FIELD 2 . Under the PM Field option look at the ah reading registered, to see what it's set at to charge your battery at present. If it's incorrect, you need to code the CAS>>KLASSE_BATTERIE>>**ah to your battery spec. Once you have done this, re-register your battery using the Tool32 program. Then go back into INPA and check the PM Field 2, to see if the new ah reading has been registered.
