Replacement battery for Bose SoundDock

The KingSener 300769-003 is a new lithium-ion battery built to replace the original power pack in Bose SoundDock SoundLink Air Mini I Bluetooth speakers. It delivers 2200mAh at 16.8V and matches part numbers 300769-001 through 300769-004 plus 300770-001 and 4ICR19/66. The white cell is produced in China and carries a two-year warranty from the supplier.

Who this suits and who it does not

Owners of the listed Bose SoundDock models who need a direct voltage and capacity match will find this part compatible. Buyers whose speaker uses a different voltage, a different connector, or a higher capacity requirement should look at another option. The battery is not intended for non-Bose devices or for models outside the stated compatibility list.

Deciding specification: 16.8V operating voltage

The single figure that determines fit is the 16.8V rating; the speaker circuitry expects exactly this potential. If the original battery label shows a different voltage the replacement will not work correctly. Capacity and part-number cross-reference are secondary checks once the voltage matches.
