I've been meaning to try this with my Sony M10. It takes two AA batteries, =
and I've been powering it with two D cells via the power socket. That works=
 ok, but it thinks it's running off a power pack plugged into the mains and=
 has infinite life - it doesn't give me any warning when the batteries are =
running low.

I was thinking I'd make some dummy batteries, perhaps some dowel with screw=
s in the ends to act as terminals to give me something I can easily connect=
 the power leads to.
