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?
