Questions about this item

Will this 5200 mAh battery fit the original compartment in my Anker A3301011 PowerConf USB-C speaker?

The replacement measures 70.00 x 19.80 x 19.80 mm per cell and matches the Anker 539028 part number, so it sits in the same space as the factory pack.

How can I confirm the new lithium-polymer pack is working correctly after I install it?

Connect the speaker to USB-C power until the status light shows a full charge, then run a typical conference call; the runtime should match the original 5200 mAh / 19.24 Wh rating.

Does the box include only the battery or are tools and adhesive supplied as well?

The package contains the single 96.0 g lithium-polymer cell with its pre-fitted connector and protective foam; no screwdrivers, pry tools or glue strips are included.
