18-Volt Deluxe Battery Compartment, Holds 2 9-Volt batteries, 2-3/16" x 1-15/16". Built-in terminals and lead wires. Mounting surface must be at least 2-3/4" x 2-1/4" (69.85mm x 57.15mm) and 1-1/4" (31.75mm) depth required.
I looked at several battery boxes before my purchase and this one is by far the best. Very solid construction and a well thought out design.

This is not about the box, which does what it's supposed to do, it's about what it brought to the active Bartolini. I heard my friend's American Fender PJ, and I thought mine sounded a little anemic next to his. Well, converted mine to 18v (like his) and the only question is "what took me so long?" definitely fatter sound, all over.
