Ok Yesturday i found out my old Philips key006 MP3 player, and it wont charge at all, it has been sat doing nothing for a long time and i suspect the battery has gone dead completely. So i want to find a replacement, i have spent many hours searching for a replacement. Below i've snapped a picture of the current one. Dimensional space for it to fit in 36x17x6mm, its a 550mAh battery, but i must say i dont mind it being higher rated if possible. It might only be a 128mb mp3 player but its a magnesium alloy case and the design is so sleek, love it!
