No. Assuming there is no internal short, the Archos could not drain the
batteries very far below the recommended 1v/cell limit that is recommended
for complete discharge of NiMh batteries. Totally draining NiMh batteries
with a resistor, light bulb, etc. is definately not recommended and can
damage the batteries, but it is highly unlikely that an electronic device
such as the Archos could accomplish this.

The 1.26 original firmware indicates that this may be an older unit. How
long have the original batteries been in use? A $10 investment in a set
of 1800 - 2000 Mah cells would rule out the possiblity of exhausted
batteries.

deep discharge is very safe, and will extend the life and number of cycles
for most users. No need for a warning about that.
