You love your Plantronics CS530, Savi W730 or Poly Voyager 5200, but suddenly it stopped working or the battery is not giving the same like time as before and want to replace the battery? I got bittersweet news for you, this is not possible and we will explain of why.
The CS530 and 5200 headsets are on over the ear only wearing style headsets, with a minimalistic design and for the same reason their Lithium-ion battery which is a smaller unit is soldered into the headset by itself and for same reason replacing the battery is not recommended as first of all, you will need to have experience in soldering small components, next to have patience and lastly willing to create a “Frankenstein monster” of your own and risking some bad results.
Back on the days, the CS530 and Savi W730 wireless headsets used to have spare replacement headsets for the bases, however as you are aware, these units are outdated and got discontinued by Plantronics and eventually the spare parts got faced out and no longer available for purchase. After that being said, the only thing to do when you reach this point would be replacing the whole system, on the bright side is that there are newer and fresher headsets from Poly (formerly Plantronics) that would be a nice fit as those outdated units and with new features that actually fill more gaps left by the old one.
For replacing a Plantronics CS530 headset you will need to upgrade to the new Poly Voyager 5200 Office Bluetooth Headset 1-Way Base, this is a Bluetooth Class 1 headset with a

If you need to upgrade your Savi W730 headset, the natural choice will be the new Poly Voyager 5200 Office Bluetooth Headset 2-Way Base. With a similar range as the old one

Voyager 5200 Office Bases are fully compatible with Plantronics EHS and lifters and its an easy transition from one to the other, simply unplug the old base from the adapters/lifters and plug the new one and would work right away.
* Special Note: When plugging the Voyager 5200 Office base, make sure that first you plug in the desk phone and not other devices as the cell phone or computer as this will make those devices the primary one and for that reason you might not answer your desk phone. If this occurs, you need to download the Poly Lens app and go to Settings and change the primary device to “Desk phone”.
If you have a 5200 UC or Voyager 5200 Office Base headset and your battery is dying, would be the same principle that we had discussed before, but in your case would be a little less complicated, and will explain below.
The replacement for a Voyager 5200 UC or Voyager 5200 Office base would be the Voyager 5200 UC Bluetooth USB Headset Teams. The process is really simple, with the


For your Voyager 5200 Office the replacement headset would be the Voyager 5200 UC Bluetooth USB Headset Teams, and the process here would be similar as described before.



Voyager 5200 UC come with USB-A BT700 dongle and might will come with a USB-A to USB-C adapter, this will depend on the manufacturing time and
