Using the well put together OEM LW battery swap DIY from Doba_s and trusting that Lemans_Blue_M was right about the MC/CSL battery being a direct OEM type fit, I figured why not, 24 lbs is a nice savings for 130 bucks. Here's the link on Doba's LW Battery Swap/Removal, etc.

I ran a LW Braile battery in my E46 Supercharged M3 and if the car sat for more than 1 day, it would not start, etc. So I had no plans on using it on the E92. But the OEM MC/CSL battery should yield enough power, and is a nice compromise for some WR.
OEM Battery on the scale.
Mini Cooper/CSL Battery on the scale.
OEM and CSL/MC batteries next to the Braile.
The OEM bracket is bolted into the appropriate place, NO AM bracket is needed, OEM fitment FTW!
The Drain is a perfect fit and placement as well.
Finshed, sure enough it's a perfect OEM fitment!
