Centenex DS-CS-PCT140SL Ni-MH Battery

The Centenex DS-CS-PCT140SL is a 2.4 V 700 mAh nickel-metal-hydride replacement cell built for Plantronics headsets. It matches the original 80639-01, 81087-01 and 81087-02 part numbers and fits the CT14 model. The green pack measures 44.76 by 20.73 by 10.68 mm and ships new in a single-unit pack.

Replaces Worn Plantronics Headset Cells

This battery replaces the factory pack when talk time drops or the headset fails to hold a charge. The jump is worth it when the original Ni-MH cell no longer delivers a full shift of wireless use. It is not for owners of headsets that use a different voltage, connector or form factor.

Simple Two-Wire Swap in Minutes

Installation requires opening the headset battery compartment, unplugging the old two-wire connector and snapping in the new pack. The keyed plug prevents reversed polarity. What usually goes wrong is forgetting to fully seat the connector or damaging the fragile wires during reassembly.
