    Battery specs

    Hello guys,

    I have a 2011 335i 6spd manual convertible (E93). I am trying to get the stock battery specs. Can you guys help me please. Also which one do you suggest for the replacement- Duralast or Bosch.

    The attached pictures are from my car and I don't see any specs there. I have no idea whether this is AGM or regular.

    Thanks.

    If you remove the stuff in the way it will give you amp hours and cca, but I you just get the BMW battery it will be the right one and register it

    I believe that Bosch is OEM for BMW.

    That is an AGM, 90 (or 92) amp hour battery. I think they are 850 cold cranking amps. Maybe 900, but I think the 900 CCA is the next step up

    Bought the Bosch one. 850 CCA /92AH - exactly the stock specs.Pepboys had a store wide 25% off coupon so was a good deal. Space was a big problem in E93 so required some time, patience and lot of muscle work.

    is it true that you have to code the battery to the car?
