Jabra Evolve 75 UC Wireless Headset Battery Replacement
I started looking around how I could replace it myself (being a DIY guy) and was unable to find the one for my model. So with whatever information I could collect I started and this turned out to be more convenient that other model that has been covered by other people.

- Battery is in the left ear-piece (without mic) and you may start by unscrewing it on one side and then raising the speaker to 90 degrees to the base on the other pivot point and push it out. You don't have to push it too hard, if you need to then you are doing something wrong.
- Then you will see 3 screws, pull the thin plastic sheet out and you will see the battery. Based on the information on the internet I ended up buying a smaller size battery on eBay
- I removed the cables from the old battery and put them on the new one and voila, headset was again wireless.
