[QUOTE=bluebee;6332297]While we're on the topic of what not to do when replacing the BMW battery with the Duralast 49-DL, see this warning from cn90:
I think those over torquing situation happen more so when the clamp isn't fully seated on the battery post.
Notice the battery post is slightly tapered. If not pressed all the way down and seated properly, people tend to over torque to get it tight.
So another point to mention, although it may be common sense, press down on the clamp until fully seated before tightening the nut.
