Replacement Battery for Plantronics CS530 CS540

This 140mAh 3.7V Li-Pol cell replaces the original battery in Plantronics CS530, CS540, CS540A and Savi CS540 wireless headsets. It matches the OEM specifications for voltage and capacity. The pack includes one battery and a HQRP coaster accessory. It is designed for users who need a direct replacement for a depleted headset battery.

Thermals Noise and Power Draw

As a low-capacity lithium-polymer cell operating at 3.7V, it generates negligible heat during normal headset use. There are no moving parts, so it adds no audible noise to the device. Power draw is limited to the headset's own charging and discharge cycles. The battery supports standard talk and standby times expected from the original equipment.

Build Fit and Constraints

The battery fits inside the existing headset battery compartment without modification. The included coaster provides a convenient rest for the headset when not in use. No additional cables, chargers or tools are required for installation. Buyers who need a multi-pack or a higher-capacity cell for extended runtime should look elsewhere.

Questions about this item

How do I install this 140mAh 3.7V Li-Pol battery into my Plantronics CS540 headset and what step is often missed?

Open the headset battery compartment, disconnect the old pack, connect the new battery plug matching the polarity, and secure the cover; the step often missed is ensuring the connector clicks fully into place before closing the compartment.

What maintenance or replacement will this 140mAh lithium-polymer battery need over time?

The battery is sealed and maintenance-free; plan to replace the pack when talk time falls well below the original 140mAh capacity, typically after several hundred charge cycles.

What limit appears first when using this 3.7V battery continuously on long calls?

The 140mAh capacity sets the runtime ceiling, so extended conversations will hit the charge limit before any thermal or voltage cutoff activates.
