Sounds like Ni-Mh in disguise to me. Just stick to the big brands I'd say. It may be related to this : http://www.americasdebate.com/forums...showtopic=1864

Now that my rig is at least halfway decent. On the floor: - Palm Tungsten T3 with Pocket Tunes 4 reading from SD cards, mostly ogg -q6 and lame standard (additional SD card and wifi card in the aluminium case, external battery pack for 12 hours of audio playback) - stock Xtra X-1...

Just ordered a silver Xtra X-1. It will power my E2c and Sony CD1700. The Palm T3's output sounds OK, but a little weak.

Now that is weird. Saw this today while commuting. As if it didn't sound bad enough : By the way.. first post!
