Introduction

Since Teufel is not a very big company, I thought to myself that it was definitely not a custom battery but something off the shelf. This is also the case and the battery is very easy to change

What you need

Step 1

              Find a replacement battery
  • Find a replacement battery. The original battery is an EVE 622632 Lithium Polymer (Lipo) battery with 3.7V 600mAh, size 33x25x5mm. I couldn’t find them in Germany.
  • A slightly larger battery is a replacement battery for a Logitech Mx Master 2 mouse
  • Unfortunately, the connector is not identical and must be resoldered

Step 2

              Open the Housing
  • The ear pads are clipped in all around. Carefully pry out with a plastic spatula.
  • Loosen 4 Phillips screws and carefully lift the loudspeaker upwards.
  • The cable on the speaker is long enough to lay it next to it
  • The battery is on the side where the ANC switch (noise canceling on/off) is. (ANC slider marked with arrow in the picture)
  • The side with the USB connection does not have to be opened
  • The battery is under the green circuit board. The circuit board has a small cutout. Carefully turn the circuit board until the cutout is under a plastic tab. Then the circuit board can be lifted out

Step 3

              Change Battery
  • The original battery is stuck down with double-sided tape and can be carefully levered out.
  • Because the plug does not fit, pinch off the original plug
  • The same applies to the spare battery
  • The spare battery comes with an extra cable (white). This is for a temperature sensor, but the headphones don’t use it. So simply cut off with the block
  • Solder the original connector to the replacement battery. Red-to-red, black-to-black.
  • Cover the solder joint with shrink tubing

Step 4

              Assembly
  • The replacement battery is slightly larger than the original. But the aluminum case can be gently pressed with your fingers so that the battery fits perfectly into the holder
  • Secure with double-sided tape
  • There is black foam rubber on the original battery. This can be snapped off and glued to the spare battery
  • Glue the battery in place, plug the connector into the circuit board and hook the circuit board back under the plastic tabs.
  • Make sure that the ANC on/off slider is hooked into the circuit board
  • Put the loudspeaker back on and screw it on with the four screws
  • Clip on the ear pads, done.

Teufel ist extrem unkooperativ was kaputte Kopfhörer und anderes Equipment angeht. Mir und meinem Bruders sind jeweils die RealBlue verreckt, zudem sein und mein Teufel Subwoofer (kaputte Kondensatoren). Ich lasse in Zukunft die Finger von dieser Marke.

Mein Akku lädt zwar noch bis led grün ist, aber nach dem abziehen des Ladekabels geht nichts mehr. Versuche jetzt einen neuen Akku zu verbauen. Das kurz nach Garantie Ablauf, schon sehr ärgerlich
