Replacement Battery for Plantronics CS540 Headsets

This Cameron & Co battery is a direct replacement for Plantronics CS540, CS540A, Savi CS540 and Savi CS540A wireless headsets. It matches the original 3.70V 140mAh 0.52Wh lithium-polymer specification and is identified by part numbers 84479-01 and 86180-01. The single-pack format provides a straightforward swap when the original cell no longer holds a charge.

Suitable for Single-Headset Users Only

The pack contains one battery, so it suits individuals or small offices replacing a single failed cell. Buyers who need to service multiple headsets at once or who want a spare on the shelf will need to order additional units separately. It is not a universal power bank and cannot charge other devices.

Steady Output for All-Day Talk Time

The lithium-polymer chemistry delivers a stable 3.70V through a full workday of calls rather than fading after a short burst. Capacity remains consistent across repeated charge cycles, so the headset stays powered for the duration of each shift without unexpected drop-outs.

Questions about this item

Does this battery come with the tools needed to open my Plantronics CS540 headset?

No, the pack contains only the 3.70V 140mAh Li-Polymer cell; you will need a small Phillips screwdriver and a plastic pry tool to open the headset casing.

Will the 3.70V 140mAh cell fit the original battery compartment in my CS540A without modification?

Yes, the replacement is built to the same dimensions as the original 84479-01 pack, so it slides into the existing compartment with no trimming required.

How can I confirm the new battery is working correctly after I install it?

Place the headset on its base; the charge LED should light, and after a full charge the talk-time should match the 0.52Wh capacity rating.
