Sharp AD-T51BT Battery Replacement

This is a simple batter dummy for as a replacement for the Sharp AD-T51BT. It's a bit smaller than the AD-S31BT, which doesn't fit.

There are at least two different batteries that I could find that will fit:

* 602060/700mAh
* 651760/1000mAh

I made the contacts from conducting foil (actually, I used the metal shielding of CAT7 wires) and super-glued them into place. With a bit of patience the battery leads can be soldered to the foil. The whole thing is wrapped in tape, as is the original.
