This replaces the tremolo cover on the back of any Stratocaster or guitar with a similar tremolo to hold a 9V battery without routing out a new cavity for it.

The battery is held between 2 tremolo springs, you'll need to move your springs to the outer edges to fit it, you might need to get stronger springs depending on the bridge.
