Compatible Replacement for GO + Play 3

This lithium-polymer battery replaces the original pack in the Harman/Kardon GO + Play 3 speaker. It delivers a 3500mAh capacity at 10.8V and matches the 68.00 x 38.50 x 35.80mm form factor. The integrated protection circuit guards against overcharge, over-discharge, over-voltage and short circuits.

Upgrade from a Depleted Original Cell

When the factory battery no longer holds a useful charge, this unit restores full portable runtime. The jump is worth it once the speaker cuts out early or refuses to power on away from the mains. A fresh pack also avoids the swelling risk that appears in aged lithium-polymer cells.

Drop-In Fit for the Speaker Chassis

The pack sits inside the existing battery compartment without modification. Its pre-fitted connector aligns with the GO + Play 3 board, and the decoded chip communicates correctly with the speaker's management system. No extra wiring or firmware steps are required beyond seating the connector firmly.

Questions about this item

Will the 68.00 x 38.50 x 35.80 mm pack fit inside the GO + Play 3 battery compartment?

Yes, those are the exact dimensions of the original C1146B-18650-3S1P pack, so it occupies the same space in the GO + Play 3.

What is the common mistake when connecting the replacement battery?

The connector must be fully seated; a partially inserted plug leaves the speaker dead even though the pack is new.

After how many full charge-discharge cycles does the lithium-polymer pack reach its rated 3500 mAh capacity?

The manufacturer states the battery delivers its best performance after 2 or 3 complete cycles.
