Replacement Battery for Bose QC35

This lithium-polymer cell is built to fit the Bose QuietComfort 35 wireless headset. It matches the original 3.7 V, 400 mAh specification and includes a fully decoded chip for correct communication with the headset electronics. The pack measures 47.00 x 10.00 x 10.00 mm and weighs 7.8 g. Buyers who need a higher-capacity pack for longer listening sessions cannot use this cell.

Capacity and Runtime

The 400 mAh rating delivers 1.48 Wh of energy, restoring the factory runtime for noise-cancelling and audio playback. It handles daily commutes and office use without issue, but extended travel days may require a portable charger. The integrated protection circuit guards against overcharge, over-discharge, over-voltage and short circuits. Users who want significantly more talk time per charge will find the capacity fixed at the original level.

Thermal Behaviour and Safety

In normal operation the cell stays close to ambient temperature and adds no audible noise to the headset. The lithium-polymer chemistry and built-in safeguards keep power draw stable during both active use and standby. The pack ships in shock-absorbing foam for transit protection and carries ISO 9001, RoHS and CE certifications. Installers who are uncomfortable with small-connector work should seek professional help.

Questions about this item

Will this 400mAh 3.7V lithium polymer cell fit my original Bose QC35 headset without modification?

Yes, it matches the AHB110520CPS part number and the 47.00 x 10.00 x 10.00 mm dimensions of the original pack, so it slots into the QC35 battery compartment directly.

How can I confirm the new battery is functioning correctly after I install it?

Power on the QC35; the headset should show a full charge indicator, deliver the rated 1.48Wh capacity, and the built-in protection circuit will prevent overcharge, over-discharge and short-circuit events during normal use.

Does the package include any tools or adhesive, or must I buy them separately?

The box contains the 7.8g battery with its decoded chip and shock-absorbing foam; no screwdrivers, pry tools or adhesive strips are supplied, so you will need to source those yourself.
