Questions about this item

Does the 240mAh battery generate noticeable heat during all-day use?

The 240mAh lithium cell runs cool under normal headset loads; its compact 35.35 x 21.07 x 4.37mm size limits heat build-up during extended calls.

Must I already own a compatible Avaya or Plantronics headset model for this battery to work?

Yes — it fits Avaya Tenovis HSG-Link DECT 2, AWH55, AWH65 and Plantronics models such as CS510, CS520, Savi 410, Savi 710, Savi Office WH300 and WO300.

Will the 35.35 x 21.07 x 4.37mm dimensions match the battery compartment in my older Plantronics CS55 headset?

The cell is listed for CS55, CS55H and CS65 models, so the 35.35 x 21.07 x 4.37mm form factor matches those legacy compartments.
