CS Wireless Headset Systems: Talk Time

All CS wireless units use rechargeable lithium-ion batteries that last for up to 500 full charging cycles. Batteries for all CS models, except for the CS70, are replaceable. TIP: To extend the life of your battery, we recommended you charge your headset whenever it is not in use. It is not possible to "overcharge" the battery.

CS55 Up to 10
CS70/CS70N Up to 6
