Questions about this item

Which Plantronics headset models must I already own for this 3.7V 140mAh battery to fit?

This battery fits only the Plantronics CS540, CS540A and CS540-XD wireless headsets. It will not work with Savi W740, W745, CS50 or CS55 models.

Can I use this 86180-01 replacement in an older Plantronics CS50 or CS55 headset I still have?

No. The 86180-01 battery is built exclusively for CS540, CS540A and CS540-XD headsets and is physically incompatible with CS50 or CS55 units.

How do I confirm the new 3.7V 140mAh cell is delivering the rated 7 hours talk time after installation?

Fully charge the headset, then make continuous calls until the battery depletes; achieving roughly 7 hours of talk time indicates the cell is performing to spec.
