That's pretty dead, even if it does work. Those batteries cost $10 at
Radio Hack, so I usually buy a battery holder that takes two AAA
batteries, attach it to the MB with double sided foam tape, and solder the
wires onto the battery posts. Total cost is less than $3 USD, and the
batteries last forever.
