Use of NIMH in DR7

["1GDW" <>]

I recently bought a Sharp MD-DR7 minidisk and have a question about 
battery use.  The internal battery is a gum stick AD-N55BT.  The 
manual instructs to use an Alkaline AA battery in the external 
battery case, with a caution against use of a rechargable battery.  
I would prefer to use a AA NIMH in the external case.  I wonder if 
any harm would occur if I did use the NIMH battery?  Anyone have a 
clue about why the manufacture would not want the use of a 
rechargeable battery?
