The problem is that the colorado.edu web site is too clever
for its own good. It makes heavy use of frames ... but
moving from frame to frame doesn't change the URL in the
browser's "location" window ... so if you find something
you like you cannot just copy the "location" and sent it.
You need to bypass the frame structure and send the URL
of the *frame* of interest. In this case, I believe
the following is the frame of interest:
There are other simulations on the same site that do not
offer to show the inner "workings" of the battery, so it's
important to have just the right URL.
