plantronics Voyager pro Battery Replacement

order your battery

separate rubber case from back of earpiece. you don't need to remove it completely like I did.

rotate the back away from the case. its basically glued in place with no other fasteners

you will need to slowly cut through the foam to separate the wires from the battery. then use a soldering iron to desolder the old battery from the board these connections go through the entire board.

solder the new battery in and test the charging before reassembly.

the new battery I ordered was slightly larger but it fit with no problems. I found the wires inside this device to be fairly robust and did not have any issues with wires breaking or dislodging.

When I re-assembled I used small amounts of gorilla glue for both the case and the rubber cover. it worked very well and has worked well since. for more details I put together a short video you can check out.
