Anita,
If I remember correctly, it was the same voltage, but higher amperage & slightly thicker battery(#2032). I have done that also & it helps, but not as much as the antenna relocation.
I think I saw that battery post when I was digging through the "knowlege base" for the antenna post.

edit: oops, my bad, It was "how to's" not knowlege base, in the electrical area...search back 1 yr. & you'll find it.
