Compatible Replacement Battery

This Cameron & Co battery replaces the original AHB110520CPS cell inside Bose QC35 QuietComfort 35 headsets. It is a brand-new lithium-polymer unit rated at 3.7 V and 400 mAh, matching the 1.48 Wh energy figure of the factory part.

Who This Suits And Who It Does Not

Owners of a Bose QC35 headset whose battery no longer holds a charge can restore full wireless runtime with this drop-in cell. Buyers who need a higher-capacity pack for extended play time, a different voltage, or a connector layout not used on the QC35 should look at other options.

Deciding Specification 3.7 V 400 mAh Li-Polymer

The single figure that decides fitment is the 3.7 V 400 mAh lithium-polymer rating in the 47.00 x 10.00 x 10.00 mm form factor. Only headsets designed for the AHB110520CPS part number will accept this exact voltage, capacity and physical size combination.
