Direct Replacement for Plantronics Headsets

This two-pack supplies 3.7V 140mAh cells built to the original 33 by 23 by 9 millimetre footprint. Each unit weighs 5.4 grams and carries the same part numbers 82742-01 204755-01 84598-01 86507-01 used across the Savi W740 W745 W720 WH500 and CS540XD ranges.

Restores Talk Time on Aging Headsets

When the factory cell no longer holds a charge the headset drops calls or powers off mid-shift. Swapping in these matched replacements returns the original runtime without soldering or tools. The upgrade is worth it whenever the existing battery shows reduced capacity or swelling.

Steady Output Through a Full Shift

An internal protection microchip regulates charge and discharge cycles preventing overcharge deep-discharge short-circuit and overheating. Voltage remains stable from the first minute to the last so audio quality does not fade as the cell depletes.

Questions about this item

What are the exact dimensions of the 3.7V 140mAh battery for the Plantronics Savi W740 headset?

The battery measures 33 by 23 by 9 millimetres and weighs 5.4 grams, matching the original size for a direct fit inside the headset earcup.

How do you install the replacement battery in a Plantronics WH500 headset, and what step is often missed?

Pop out the old cell, then slide the new battery in ensuring the connector clicks fully into the socket; the step often missed is verifying that the plug is seated squarely before closing the cover.

When will the 0.5Wh replacement cell need changing again under normal daily use?

The lithium-polymer cell typically delivers the original talk time for about two years of daily charging cycles before capacity drops enough to warrant another swap.
