I try to make sure I have a fully charged gumstick battery in the
minidisk recorder, in the older models, when you then attach the
external AA battery holder it uses that one first (don't know about the
DR480/DR7 and rechargeable batteries work fine (they may start out with
a lower voltage but it doesn't drop by much I'm guessing). Alternatively
get yourself a couple more gumstick batteries, mine in the DR480/DR7
last me quite a few hours of recording/playing and the charger isn't
that big (and fits all Sharp MD recorders).
Regards
