Replacement Battery for BOSE Soundlink Mini 2

This lithium-ion battery replaces the original pack in the BOSE Soundlink Mini 2 speaker. It matches the 7.4 V voltage and 2200 mAh capacity specified by the manufacturer. The pack fits part numbers 088772, 088789 and 088796. It is intended for owners who need a direct swap without modification.

Thermals Noise and Power Draw in Normal Use

The cell chemistry is lithium-ion, which runs cool during typical playback at moderate volume. No active cooling is required and the pack adds no audible noise to the speaker. Normal charging and discharging stay within the designed voltage window. The unit weighs 120.0 g and measures 113.44 x 38.14 x 40.88 mm.

Behaviour Under Sustained Load

During extended play sessions the battery maintains a stable 7.4 V output until the protection circuit engages. Overcharge, over-discharge, over-voltage and short-circuit protections are built in. A new pack reaches full capacity after two or three complete charge cycles. It is not suited for devices that require a different voltage or form factor.

Questions about this item

How do I install this battery in my BOSE Soundlink Mini 2, and what step often goes wrong?

Remove the old pack, align the connector, and press it in until it clicks; the step people miss is not seating the connector fully, which leaves the speaker dead on first power-up.

What maintenance or replacement will this 2200mAh lithium-ion pack need later?

Run 2–3 full charge cycles when new to calibrate the fuel gauge; after that, no routine maintenance is required — just replace the pack when run-time becomes too short.

What limit appears first during sustained high-volume playback?

The 7.4 V pack will hit its voltage floor and trigger the speaker's low-battery shutdown before the 16.28 Wh capacity is fully drained.
