Are X60s and X60 batteries interchangable?

Just wondering if that's true or not.... thanks all.

X60 batteries (the 4-cell cylindrical and the 8-cell cylindrical) will fit the X60s. (Note: screwing a plastic "spacer" to the cylindrical batteries will fill the gap that's left, but it's not necessary). However, the X60s flat battery (4-cell prismatic) will not fit the X60.

The reason is because the fan on the X60, being wider than the fan on the X60s, encroaches on the opening which holds the wider (but flatter) X60s battery.
