Replacement Battery for Plantronics CS540

This 140mAh lithium cell replaces part numbers 84479-01 and 86180-01 inside Plantronics CS540, CS540A, Savi CS540 and Savi CS540A wireless headsets. It restores talk time for office workers who rely on the headset for daily calls. The pack fits the original battery compartment without modification. Buyers who need a higher-capacity pack for longer shifts cannot use this model.

Built-in Protection and CE Certification

The cell includes a microchip that prevents overcharging and eliminates memory effect, so the battery can be topped up at any point without reducing its useful life. CE certification confirms the pack meets European safety requirements. No charging dock, tools or firmware updates are supplied with the battery.

Straightforward Swap with Correct Orientation

Installation consists of opening the headset battery door, disconnecting the old pack and connecting the new one using the existing connector. The compact 24.50 x 14.80 x 5.20mm dimensions match the original cavity. The only common issue is reversing the connector polarity, which prevents the headset from powering on until corrected.

Questions about this item

How often will the 140mAh 86180-01 battery need replacing in a CS540 headset?

The 140mAh cell has no memory effect so it can be charged whenever convenient; typical talk-time cycles last one to two years before capacity drops enough to warrant a swap.

What limits continuous talk time on the 140mAh pack?

The 140mAh capacity sets the hard ceiling; once the stored charge is depleted the headset powers down until recharged.

Does the 86180-01 battery get hot or noisy during all-day use?

The pack includes over-charge protection and a built-in microchip, runs silently and stays cool under normal daily charging cycles.
