Do you want the best headset? 
Replacing the battery in your Plantronics CS540 (C054) wireless headset is easy! On average customers will replace their battery about every 2 years. If you notice the battery no longer holding a charge like it once did, follow these quick steps to replace your C054 battery.
Step 1
Remove the battery door cover on your Plantronics C054 earpiece.
Step 2
Located on the battery is a small white connector with a black and red cord connected to it. Pull the white connector away from your C054 earpiece and the battery will easily disconnect.
Step 3
Reconnect the new CS540 battery the same way it was disconnected and re-install the battery door cover. Let your headset charge for at least 3 hours for a full charge and your headset is refreshed and ready to be used!
