Hey all

got a 61 AH mini battery to save weight
coding it into DME

- coded CAS thru NCSExpert, changed 90 to 60 ah_agm
- re-read ECU and it's well labeled/coded
- registered new battery via ista
- also registered via tool32
- when i check on ista as well as inpa, it says 86 AH (it was previously written 90) even though it's coded in NCSExpert CAS as 60

any ideas?

thanks

**update
Changed VO in CAS and NFRM
Was only able to change to A070 (70ah)
Tried 55 and 60 didnt work
Then i recoded the CAS. Tried 55, 60 and 70
Then registered it after each time
When then checking battery info in inpa and ista, when i code CAS to 55 or 60, it reads 86. When I code to 70, it reads 70.

Seems to me you can't code a lower AGM value.

Anyone have anything to add or suggest that is different so the car sees the proper 60 ah value?

Thanks again

Thanks just ran into same problem trying to code 60ah antigravity battery. NCS Expert clearly shows coded as 60 ah_agm, but in ISTA shows up as 86ah. I just changed it to 70ah_agm and now ISTA shows 70ah.

Same exact scenario, 60 Ah Antigravity battery, coding as "60ah_agm" then registering battery and INPA shows 86 Ah, changed to "70ah_agm" and INPA shows 71 Ah so left I left it at "70ah_agm".

I think most people with 60 Ah lithium ion batteries follow the recommendation to code as 60 Ah but they don't double check to see if that's what the car actually accepts as the installed battery capacity.

Now one nice thing with the Antigravity battery is it has intelligence to monitor the battery and not allow it to be overcharged so I think you should be fine with either coding option.
