Using the small plastic spudger to assist, begin lifting up and removing the foam inserts with attached backing tape.

Where do you find a battery to match the connector size?
Thanks, I have the Evolve 2 85h, which is similar and this helped me fix it.
I wish to add that my headset refused to charge at all, due to the battery voltage going to low and then the headset did not manage to trickle charge it to a safe charging level. Thus it was dead and Jabra would not repair or replace it claiming the warranty had passed.
By applying 3.8 volts (and limiting it to 300mA) on a test pin connected to the battery + pole for a split second, the charger was tricked into accepting the battery and started charging. Now everything works fine.
Photo of were to apply the voltage. Plus is red. Ground is black.
Some notes -
How it started - I got a battery low warning while listening on a video conference. I attached a USB-C charger cable while wearing the headset. After about 30 minutes the headset just died.
When connecting to a computer, the Jabra App recognized the headset, but said 0% battery. No charging and no Bluetooth communication was possible.
Does it has 2 batteries? One on left and one on right?

It has just one battery
Hi sir, I think your guide is incomplete. Do you have the opportunity to bring a sequel?

The battery is under the left earcup.
NOT the earcup into which you plug the USB cable.
Not sure why the demo asks you to disassemble the right earcup...

These instructions could use some work! There is no need to disassemble both sides as the battery is under the left ear cup only.

I have just disassembled mine, Jabra Elite 85h, model OTE100. The cushions (as described in this step) can not be removed. If that's the case, The foam in the center has to be removed to access the speaker screws. Undoing the screws will split the headphone in half, releasing the pad together with the speaker. This will uncover the rest of the components
Besides, I agree with the rest of the comments - If you're after the battery there is no need to disassemble the right headphone as the battery resides in the left

This is very easy. I just finished mine. You dont need special tools as a tweeser will pull the wire connection apart. The cushions will come off and are replaceable. Do just the left one. Pull it apart like you mean it. Do have a small piece of thick double-sided tape on hand. The AOLIKES 3.7v 850mAh battery from amazon works but the wire is a bit short to orient it like the original. Just don’t press it in place until the circuit board is screwed in place. All I can say now is that it’s charging.
Lastly, I’ve learned from experience that if you’re using metal screws in plastic, when reassembling turn counter clockwise until you hear a click. Thats when they are aligned properly and you’re less likely to strip the thread.
