Can verify this...the e53 X5's battery location is not long enough to accept the H9/95R battery's extra length. The e53's generational cousins (e38/e39) though...can mount either the H8 or H9 battery size...as well as the later generation X5s (e70 & f15 & g05). But the e53 X5s battery box doesn't have enough room to accept the H9.

The left side of the battery box (the side where the vent hose connects) has raised ridges on the bottom of the box that are there to prevent the battery from moving sideways and crushing the vent hose...and the right side of the battery box is where the battery hold down clamp is secured to prevent the battery from moving up/down as well as side to side. So the extra length of the 95R/H9 battery prevents it from fitting correctly in the battery box. But the 49/H8 or 94R/H7 battery will fit:

{left side has built-in ridges that prevents the vent hose from getting crushed between the left battery box's wall and the battery}



{the right side only has room for the battery hold down clamp}
