I have a fully loaded 2011 335i sedan that I need to code & register a new battery for. The factory unit was a lead acid / traditional wet cell (white jacketed) OEM unit with 720 CCA & 90 AH. Figuring out the AH on other batteries is the easy part if you know the RC figure.

However, I'm trying to install a Group 49 DieHard AGM & it has 101 AH. Bu the listing for AGM batteries in the coding system only goes up to 90 AH… ;-(

How do you fellas go about coding for AGM batteries that don't fit the listing or have higher (AH) values then the coding list allows… ?

Code it as 90Ah and will be ok.

Yup. Exactly what Carly says to do on their site.

I appreciate all your help. The only thing I forgot to ask is, if the AH rating of the battery is higher then the available code listing allows (I realize it won't hurt the battery) but wouldn't IBS essentially be undercharging that battery it's whole life… ?

Not a big deal in the long run but just wanted to run that by you fellas & get your insight.

Possibly, yes.

Thank you. I guess it wouldn't be that bad. And that's exactly what weekly maintenance with my C-teck battery charger could help with to safely & gradually top is off from time to time.
