Verify the exact model

Confirm your speaker is the Soundlink Mini 2 and that the original battery carries one of the listed part numbers: 088789, 080841, 088772 or 088796. The replacement measures 113.44 x 38.14 x 40.88 mm and weighs 300.0 g, so the battery compartment must accommodate those dimensions. No other speaker models are supported by this cell.

Restores original runtime for ageing or failed packs

The unit replaces a depleted or swollen battery that no longer holds a charge, returning the speaker to its factory play time. The upgrade is worthwhile when the existing pack shows reduced capacity, sudden shutdowns or physical deformation. It does not add extra capacity beyond the original 2200 mAh specification.
