In many (but not all) circumstances, you can solve this problem by using the C cell and making up the battery length difference with a few quarters-- typically three or four.  There is a 12 mm length difference between a C cell and a D cell, and quarters are about 2 mm thick, so if your gizmo has a really weak spring it could take up to six quarters to do the job.
<P>
Yes, commercial battery size adapters are available.  
They typically cost between <A href="http://www.greenbatteries.com/battery-adapter.html">1.5</A> and <A href="http://thomasdistributing.com/batteryadapter-index.htm">three</A> dollars and can only be used for the one purpose-- adapting battery sizes. (Well, that, and as a set of <A href="http://www.evilmadscientist.com/article.php/matryoshki">matryoshki</A>.) Using quarters can also potentially end up costing as much as $1.50, but it can go straight back into your wallet when you're finished!  Much more importantly, when you really need it, you can probably find a few quarters no further away than your pocket.
