'08 E350 Sport

What is the correct battery size? H6/48 or H8/49?

What was the original battery chemistry, flooded lead acid or AGM?

Thanks!

I'm pretty sure it is grp 49 but can't answer whether AGM or not from factory. I used to think if the vehicle had the little vent tube coming from battery it was not an AGM battery but not sure it that is accurate or not.

My last two Mercedes-Benz '99 '06 and '17 Corvette all are AGMs and have vent tubes. I get the Die Hard Golds from Advanced Auto Parts for them.
