Compatible Panasonic drive-thru headset battery

This Centenex Electronics DS-CS-PWT205SL lithium-ion pack replaces Panasonic 2050BAT and 2051BAT cells in Attune Aio 2050 and Ultraplex II 2051 wireless headsets. It also fits WX-CH2050 and WX-CT2050 units using part numbers PA12110026 or WX-C2050BAT. The 3.7 V 1700 mAh rating delivers 6.29 Wh of capacity. Builders needing a different voltage or form factor should look elsewhere.

New OEM-compatible lithium-ion construction

The black cell measures 60.37 x 40.32 x 14.64 mm and arrives brand new with 100 % OEM compatibility claimed by the supplier. Lithium-ion chemistry provides stable voltage through the discharge cycle for consistent headset audio. No charging cradle or cable is included in the package. Users requiring a hot-swappable multi-bay charger will need a separate solution.

1.7 Ah capacity decides runtime

Rated at 1.7 Ah the pack determines how long a drive-thru headset operates between charges. Matching the original 3.7 V nominal voltage ensures the headset fuel gauge reads correctly. If the application demands higher capacity or a different chemistry this cell will not meet that requirement.
