My car doesn't have start stop and battery is marked as 70ah
Does this mean it isn't AGM?
Does this mean it isn't AGM?
Will an AGM battery be marked as such?

- Start date
Not sure what the obsession is with batteries, maybe I haven't owned my Z4 long enough. The term "AGM" relates to the material the battery is made from, it indicates performance suitable for, but not restricted to, start stop cars. Look at the [insert battery maker's name here] website, type in your car, and bingo you should get a choice.
AGM = Absorbent Glass Material. Nothing else, not Carlos Fandango (remember him?), not super duper, just another battery but better/higher performance than the leaky acid types of my youth. I have one in my Z3 and I can assure you that car doesn't have start stop.
This may help you...

Thanks Roddy - I asked as I want to use my Ctek to recondition the existing battery and not sure whether to choose AGM mode or not - cheers
Batteries are discussed a lot here especially this time of year when its cold and they begin to fade
I guess its because these cars are so sensitive to a weak battery and throw up so many errors when they are low. So many problems fixed with a replacement battery its hard to believe. Throw in a forum where we get several new members every week who are unaware of how sensitive the cars are to weak batteries its easy to see then why they are discussed so often

OK thanks all - that's why I asked - I checked the battery and couldn't see any reference to AGM on it - no idea if it's the original battery from 2013 or not - I also thought I read something that said an AGM battery in an E89 would typically be of greater capacity than 70 but I could have made that up

I’ve recently replaced the battery in my e89, an AGM 70ah. I’m not making it up

Bet your 70 AMG is 760 amp :wink:
