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.
I also would like to know how to find a battery that matches the size, or at least gets close enough. Unfortunately just by looking up "3.7v Rechargeable Lithium Polymer Battery" I am finding quite the wide variety of shapes and sizes...
On the Battery is a code 553436 which is the form factor of 55mm x 34mm x 36mm. A quick google search couldnt find one suitable for the jabra, the guide speaks about a 2 pin jst but you need a 3 pin battery.
