    • Once the cover is removed, locate the motherboard on the back shell (the left component in the third image). The motherboard will be the middle component as shown in the third image.

    • To extract the motherboard, remove the seven Phillips head screws used to fasten the motherboard to the unit.

    • The battery is located on the motherboard. Two wires, red and black, are soldered onto a small PCB (printed circuit board) connecting the battery to the motherboard.

    • Be aware of the power button that is located between the back shell and the motherboard on the lower right corner.

    • The original battery is soldered onto a protection circuit on a small external printed circuit board (PCB) where two wires (red and black) attach to the motherboard.

    • On the PCB, the red wire (positively charged) is soldered near the battery’s positive post. The black wire (negatively charged) is soldered near the battery’s negative post.

    • Determine the positive and negative posts on the new battery in order to correctly wire it to the PCB.

    • You may need additional wires to solder the (+) and the (-) of the new battery to the PCB in the same way the old battery installed.

    • Solder the new battery to the small PCB, as shown in the second image. The PCB is plugged (white plug)

    • Charge the battery with the USB receiver on the Cybook Odyssey before mounting the battery onto the unit.

    • Verify that the Cybook functions properly when the battery is charged and the USB cord is unplugged.

un tutoriel trés simple .j'ai remplacé la batterie par une batterie d'origine samsung S4 pour 8€90.

la récupération de la petite carte électronique sur l'ancienne batterie est très facile à déssouder.

hi ! I just got an S4 Battery, but it seems bigger, and it says 2600 mAh ... is it still ok ? :/ thanks

I think it is ok. All batteries for galaxy S4 do not show the mAh (I do not remember what was written one the one I have put in the cybook). But you can measure the battery, the dimensions I mentioned in the instructions are about 5 x 46 x 60mm. For the capacity, 2600 mAh it is better than the initial 1600 mAh (but voltage must be the same, or very near 3,7V).

This tutorial should be avoided as possible, the Cybook Hardware is NOT MADE to charge such a battery, you risk fire/explosion problem by doing that..

Never mess with battery that are not made for a device

Godzil, you are right. Although I had no problem with the battery of galaxy S4 installed in my cybook for more than one year, I indeed recommand you to take a battery which has the same characteristics as the original battery.

The characteristic of the original battery is Lipo 1650mAh, 3.7V and dimensions are about 5x46x60mm.


You can see such batteries for example here :


This one is 5.1 mm x 46.1 mm x 59.1 mm, so lightly more thick (0.1mm), it should fit well in the cybook.



These two are 5x50x60mm but I think they should also fit well in the cybook.

I modified the tutorial to take into account your remarks. Thank you.
