Lithium batteries don't like being discharged at such a h=
igh rate. Most cells such as a CR2032 have a maximum drain of

15mA with a typical rate of 200 uA. Lithium batteries ar=
e good for low discharge rate applications such as memory backup. >

You could scope the voltage of the battery as you run the=
motor and you'd probably notice a rapid decrease in voltage.

I would suggest using an Alkaline battery like an N cell =
which looks like a stubby AAA battery but only weighs about 6 grams.=

They are available from Radio Shack or Digi key.
