Compatible Replacement Battery

The KingSener 071478 is a new lithium-ion replacement battery built for the Bose Soundlink Revolve+ Plus 2 speaker. It restores portable playback when the original cell no longer holds a charge. Users who need a direct swap without soldering will find the form factor identical to the factory pack. This unit is not for devices that require a different voltage or connector layout.

Voltage and Capacity Match

The pack delivers 7.4V and 2600mAh, matching the design specifications listed under part numbers 739617-1110, 858366-1110 and 745531-0010. Confirming these figures against the original battery ensures the speaker charges correctly and reports accurate runtime. Buyers who cannot verify the original part number should not order this model.

Conditioning Guidance Included

The supplier includes a printed tip sheet that explains how to condition the cell: fully charge and discharge at low current two or three times, avoid leaving the adapter connected during use, and store above 80% charge if unused for a month. Following these steps helps the pack reach its rated capacity and prolongs service life. No additional cables, tools or software are bundled.

Questions about this item

How many hours of playback does the 2600 mAh capacity actually deliver in a Bose SoundLink Revolve+ Plus 2?

The 2600 mAh cell restores the original run-time; exact hours depend on volume level and content but match the factory specification for this speaker.

What connector standard does the 7.4 V pack use and what does it limit?

It uses the proprietary Bose connector keyed to part numbers 739617-1110 and 858366-1110, so it only fits the Revolve+ Plus 2 and cannot be adapted to other devices.

Will the replacement battery sit flush in the speaker’s base without gaps?

Yes — the pack is built to the same external dimensions as the original, so it seats securely in the existing compartment with no modification needed.
