Speakers Needing a Fresh Cell

Owners of the compatible Anker conference speakers who notice reduced runtime or failure to hold a charge will restore full portable operation. Users whose speaker uses a different form factor or voltage should not purchase this pack.

Questions about this item

Which Anker speaker models does this 6700 mAh 3.7 V pack replace?

It is a direct replacement for the Anker A3301011, A3305 and PowerConf USB-C Conference Speaker, matching part number 539028.

Will the original charging circuit and fuel-gauge in my PowerConf speaker work with this lithium-polymer cell?

Yes, the pack includes a fully decoded protection chip so the speaker’s original charger and battery-level indicator function exactly as they did with the factory cell.

After fitting the battery, how can I confirm it is operating correctly?

Charge the speaker fully, then run a typical conference call; the battery indicator should track smoothly from full to empty without sudden jumps or early shutdown.
