Answer to: Device plugged 24 hours a day - battery replacement/removal possible?I've got an Archos HC 35 with the same problem. I've adopted a slightly different solution. As I only want to be able to use it on external power I've added a diode from 5V to the +ve battery terminal. The voltage drop across the diode brings the voltage down to just over 4V, about the same as a charged battery, and the use of a diode avoids any possibility of the charger trying to feed back into its own input. I chose a 1N4001 diode (as it has sufficient current rating), cut all 3 wires to the battery and connected the anode of the diode to the top of the component marked T next to the micro SD connector and the cathode of the diode (marked with a line) to the red battery lead. It is now working happily again.
