E46 Convertible Battery : Should I pick normal or AGM?

4477 Views 20 Replies 13 Participants Last post by  RRRM8E
I have a 330Ci vert that I don't use a lot, battery is dead and I am deciding between buying a normal group 94 battery or an AGM.

From what I researched, I didn't find enough information about AGM batteries with E46 verts. I read that they have an special "anti-vibration" setup; which got me thinking that's what AGM batteries are for as a benefit. However, I think these batteries didn't even exist back then.

Any recommendations?

I've used regular wet cell batteries for many years in my cabrio. Couldnt see any advantage to almost double the price for AGM. Keep in mind you need H7.

For $20, go AGM. When i shopped a year ago it was a 50% premium which didnt seem cost effective.
