Battery not charging above 12.2v

Like Oolas above says anything will do but I'd go with something close to OEM spec (believe my E90 is 90Ah/900CCA but maybe due to more options etc). Should you differ from the spec, you need to "code" the car i order for the battery mgmt to keep track of consumption/charging. Regardless of OEM spec or not you need to "register" to let the system know you have a new battery. Both coding and registering should be possible to do with for example Carly.

Thanks man. My first thought is as well go for a 90ah/900cca plus; if price is in the nearabouts factory specs.

For the "register" I am still debating. Dont want to use carly because they now charge for the dongle and for the app which only last for 1 year. Do not agree with that business model.

On the other side I was planning on doing it with Rheingold. I have the 3.45 version in a VM on my Mac but never tried it to connect to the car. From some posts I read it is not that difficult.

Any alternatives? I havent found Torque app in IOS and dont know if BlueDriver or FixIt can do this job, I would think not.

Not sure how much the differences are in charging depending on battery age but I personally wouldn't skip registering after investing in a new. Also, seem you have some additional checking to do assuming our current went bad after only 2 years.

Good luck
