You can replace the battery in your CS50-USB/CS60-USB headset, if necessary. You may need to replace your battery if your headset:
  • Does not power on (no green light)
  • Never fully charges
  • Seems to fully charge, but you notice a decrease in talk time
The replacement battery's part number is 64399-01. You can purchase it from our web site or from one of our distributors.
To replace the battery:
  1. Pinch both sides of the battery cover and lift to remove. TIP: Sometimes these battery doors stick, so you may need to pull or wiggle with some force.
  2. Slide the battery out and gently separate at the connection. Do not pull the battery out by the wires.
  3. Connect the new battery and slide it into place.
  4. Pinch both sides of the battery cover and slide and lock it into place.
