Plantronics Wireless Headsets – Batteries

Plantronics wireless headsets are available in several families which includes the CS50, CS55, CS70N, CS351N/CS361N, the new CS500 series and the new Savi W700 series.  All of these wireless systems use Lithium Ion (Li-on) batteries in the ear pieces that need replacing periodically, typically after about 2 years, although this varies depending on usage and how often they are charged. If you as a user notice that the battery is not holding its charge for more than a couple of hours, then it is time to get a new battery.  And if the headset is mission critical, then stock up on some spare batteries.

Here are the batteries for various headset models along with some installation tips.

64399-01 Battery for CS50/CS55

64399-01 Battery for CS50/CS55

The 64399-01 is the replacement battery for the CS50 and CS55. To replace this battery, remove the cover on the underside of the earpiece, unhook the tiny electrical plug and remove the old battery, then connect the new battery and replace the cover. This process can be a bit tricky, so if you have problems, see the detailed procedure at this link.

Tip: To squeeze a bit more life out of an old battery while you are waiting for a replacement, try resetting the CS55 system. Here’s how.

The Savi W740 cradle will mount on the Savi Office WO100 base.  Note you will need to order Headband, neckband and/or Earhook Fit Kit separately with the W740 upgrade.
