Direct replacement for Jabra Evolve 75

The Cameron & Co DS-CS-JBR750SL is a 400mAh 3.7V lithium-polymer cell built to fit the Jabra Evolve 75 headset. It matches the original AHB572535PST part and restores the factory runtime for professionals who rely on wireless calls throughout the day.

No active cooling or power draw in use

As a passive battery pack it generates no heat, produces no noise and draws no power while the headset operates. The 1.48Wh capacity supports normal talk and standby cycles without adding thermal load to the earcup.

Restores original wireless freedom

Swapping the worn cell returns the headset to its untethered design so users can move around the office or home without a cable. The black 36.60 x 25.50 x 5.50 mm pack installs inside the existing housing and requires no extra software or accessories.

Questions about this item

How do I fit the DS-CS-JBR750SL pack into the Evolve 75 headset, and what step do people miss?

Open the ear-cup compartment, disconnect the old pack, connect the new 3.7V 400mAh unit observing the red and black leads, then close the cover — the step often missed is securing the small retaining clip before snapping the cover shut.

What maintenance or replacement will this 400mAh Li-Polymer cell need over time?

No routine upkeep is needed; when talk time falls well below the original 1.48Wh rating, simply swap in another DS-CS-JBR750SL pack.

What limit appears first during a long conference call on the Evolve 75 with this battery?

The 400mAh capacity sets the runtime ceiling — expect the headset to signal low power once the 1.48Wh reserve is depleted.
