Re: battery sled for Sharp 722

Dan,

Wouldn't it be simpler to use the 722's external battery case for a
single AA battery?  Sharp claims the 722 with internal Li-Ion and
external AA batteries is good for around 11 hours of recording at
standard quality setting.

If you prefer not to use the external battery case, on eBay I found
replacement Lithium Ion batteries (model AD-S31BT), price $8.50
including shipping.  Sharp says the fully-charged 800mAh Li-Ion
battery will provide 8 hours of recording time.

Using the standard minidisc, you will be changing discs after 80
minutes of stereo recording.  It only takes a few seconds more to pop
in a new battery, as needed.
