Replacement Battery for Bose Soundlink

This 3.7V 350mAh lithium-polymer pack replaces the AHB571935PCT-01 cell inside Bose Soundlink Around-Ear II, AE2, On-Ear and OE wireless headphones. It restores the original 1.30Wh capacity so the headphones run as long as they did when new. The part also matches the 714675-0030 reference used by the manufacturer. Installation returns the headset to daily listening duty.

What the Pack Changes

Swapping the worn cell for this new unit restores full playback time and removes the need to keep the headphones tethered to a charger. The 1 year replacement warranty covers the pack itself, giving a safety net if the cell fails early. No software, cables or adapters are included because the battery slots straight into the existing compartment. The change is purely electrical — no firmware updates or pairing steps are required.

Who This Suits and Who It Does Not

Owners of the listed Bose models who notice reduced run-time will get back the original wireless freedom. Buyers whose headphones use a different part number or voltage should look elsewhere, as this pack only fits the models named above. Technicians needing a bulk quantity or a different chemistry will not find those options here. Anyone expecting a complete headphone unit instead of a single cell should choose a different product.

Questions about this item

How often will the 350mAh lithium-polymer pack need replacing?

The battery is designed as a long-life replacement; typical lithium-polymer cells in headphone use last several hundred charge cycles before capacity drops noticeably.

What limits continuous playback time on the Bose Soundlink Around-Ear II?

The 1.30Wh capacity sets the runtime ceiling; once the pack is drained the headphones stop until recharged.

Does the 3.7V cell run hot during all-day listening?

Lithium-polymer chemistry stays cool at the low currents drawn by wireless headphones, so heat and fan noise are not an issue.
