Device plugged 24 hours a day - battery replacement/removal possible?

"I had the same problem the other day and replaced the battery because the gadget will not power up without a battery connected.

The only way to use without battery would be to power it with 3.5 to 4V via the battery contacts which I felt was not going to be worth the effort to connect a DC-DC converter from 5V (USB) down to that.

The 3 wires are:

red is the positive (+) contact of the battery and is connected to the board as 3rd contact counted from the top left of the boardblue is the temperature sensor (T) contact of the battery and is connected to the board as 2nd contact counting from the top left of the boardblack is the negative (-) contact of the battery and is connected to the top left contact on the board

The battery I used is a Olympus LI-42B replacement battery (WARNING it got a lower capacity [750 vs. 600] so be carefull it doesn't overheat. Higher capacity one would be better but I noticed too late that it wasn't 750mAh as I had searched for).

I soldered the wires of the previous battery onto the new battery and put it on the back of the gadget (it is slightly to thick to fit inside).

I've used it for a bit and so far it is all fine with the new battery staying cool and the gadget working as before.

Hope that helps,

"Hi,

I have just replaced an external battery. I have 3 cels 1,2v 3500ma NI-MH in serial.

3x1,2v = 3,6v. Dont use the temp connetion.

It is a little big for this radio but it works now.

I hope others can use this info.

"Hi iam back to tell that this is not working because there is no temp sensor in the original battery !!!

The blue wire is a charge wire!!

What i now have done is i disassemble the old accu carefully. On the original wire, in/on the accu, is a little print. From that point is the accu charging.

So cut the two accu wires + and -. Now you have a little print whit on one site 2 flat wires and on the other site the original red, blue and black wire.

I replace this little print in to the Archos radio and make an kabel to the outsite for my new accu.

Now you can use for example a smartphone accu. see link.

This accu is 1800mhu and its working now. he is loading on the radio.

Do not disassamble the accu its self only seperate the accu from the little print."

"Hi mates,

found an interesting solution on youtube which works fine.

Link is: https://www.youtube.com/watch?v=I-pjLIVI...

It is actually about a NEXUS 7 but it is fair enough.

For the Archos: look twice the film, remove backcover, prepare the USB-cable, connect it with the black cable and the red one (near the black one) on the board. Wait a little bit (5 minutes). Thing is that the LED must turn green without blinking. After the 5 minutes plug in another loader cable into the usb port of the ARCHOS. LED should blink now. Power up your ARCHOS. Smile. I did.

"Hello,

I've got a boot problem with the Archos HC 35. I guess this a battery problem and I would like to open the Archos to have a look. But i don't know how. Could someone post some tips or pictures about this operation ?"
