Compatible Battery for Bose Headphones

This 3.7V 120mAh lithium-ion pack replaces the original CP1654 and LIR1654 cells in Bose SoundSport Pulse and SoundSport Wireless headphones. It restores the 0.44Wh capacity your headphones were designed for. The package includes installation tools so you can fit the battery yourself.

For Owners of Two Specific Bose Models

This battery fits only the SoundSport Pulse (762518-0010) and SoundSport Wireless (761529-0010). It will not work in other Bose headphones, earbuds, or any other brand. Buyers who need a replacement for a different model should look elsewhere.

120mAh Capacity at 3.7V

The single figure that decides compatibility is the 120mAh capacity at 3.7V. Your original battery must be marked CP1654 or LIR1654 with the same voltage and capacity. If those numbers differ, this pack will not fit or function correctly.

Questions about this item

Will the CP1654 pack fit inside the Bose SoundSport Pulse 762518-0010 earbud housing?

Yes, the CP1654 LIR1654 pack is built as a direct replacement for the original battery in the SoundSport Pulse 762518-0010 and SoundSport Wireless 761529-0010 models.

What installation steps does the kit cover and where do people usually go wrong?

The kit includes plastic pry tools and tweezers; the common mistake is applying heat directly to the cell instead of warming the adhesive around the earbud shell.

How long before the 3.7 V 120 mAh cell needs replacing again?

Typical lithium-ion cells of this size deliver several hundred full cycles; expect a fresh pack when run time drops to roughly half of the original 0.44 Wh capacity.
