I haven't ever used extra wire with Radio Shack type battery holders. They
just need a couple of small modifications. The goal is to get the battery
holder to sit flat on top of the two chips on either side. The metal contact
pins on the holder are a bit too close together but they are also a bit
long, so just bend them out until they reach the solder pads. There are also
three little plastic "leg" pins on the bottom of the holder. You need to cut
one of them off to get the holder to sit flat.

Once you have it so it looks like it will sit flat, fill each solder pad
with solder, then coat the metal pins on the holder with solder, set it in
place and reheat both solder pads. Done.

Yep. They work, they're cheap, and they're easy to find when it comes time
to replace them. Besides, I'll probably be selling this machine anyway, so
it isn't necessary for me to ensure that the battery lasts forever.
