Battery is a snug fit under the three brackets, as far as thickness goes, but the three "ears" over the battery could be "adjusted" up a little to compensate. Average thickness of the brown battery is 1-11/16". 1.25" would be loose and bang around. Hold down clips wouldn't touch it.

(C-size and D-size batteries for comparison.)

Seems there's plenty of thickness for C's, even D's, but 4 D cells in there leaves no room for enough 9-volts.

Ultimately, the two inside brackets have an upper limit as there are bends and setback cutouts for the loop coil support formed into them - about 1/16" more thickness allowance. This translates into a useable thickness of a max of 1-5/8". The catalog diemnsion of 1-1/8" seems way too thin??? A typo propagated thru the various catalogs?? I see why you were worried about C-size....hmmm.

The width has no wiggle room - the outside removable clip canot be shifted in its hole or the top wood case will touch. Same with height dimension - battery is about flush inside the case when closed.
