Subject: Archos Battery Voltage issue?
From: Alan C (nixed242_at_earthlink.com)
I discussed this recently with some people on the rockbox irc channel, and
they referred me to the list. Basically, it seems that there might be a
voltage issue with my Jukebox Recorder (see specs below). When my player
runs it's batteries down to 50%, it begins to act strange. The sound begins
to cut out for long periods of time even though the screen still continues
to show that the song is playing. The red light comes on for a while when
the sound cuts out, and the hard drive begins to make clicking noises as
well. It's almost as if the disk doesn't have the power to spin up to speed.
At this point, the batteries begin to run down a lot quicker due to the
excess disk spinning.
Someone suggested to me that I should replace the shelf batteries, which I
did, with four of a larger capacity (1800). I tested them out with a full
day of use (Normal Play and no shuffle), only to have the same problem occur
at 50% battery level. The battery contacts inside the archos are fine. I
pulled one of the coils out a bit, and no dust was found blocking any of the
I tried looking through the Debugger Battery readings as well. The
battery voltage charge fell between a low of 4.78 to a high of 5.03 during
this period. I mainly used the Archos with Rockbox since I bought it, but
did remember it happening once with the Archos firmware 1.28. Any help or
advice with this problem would be appreciated. I read some threads in the
bugs listings that sounded a bit similar where people are having their sound
cut out. I even noticed that one person had the same model as mine. Could it
be a problem that's isolated to this model only?
My specs are as follow...
Archos Jukebox Recorder 20 - JBR20101
Archos firmware - 1.28
Rockbox - 2.0
Battery - 1800
All my Rockbox settings are set to the default.
