Replacement Battery for UE Boom 2

This Estry lithium battery replaces the original 00798-601-8207 cell in UE Boom 2 and UE Boom 2 Ultimate speakers. It is a new rechargeable unit built to the same specifications as the factory part. The pack includes overcharge, over-discharge, over-voltage and short-circuit protection for safer operation. Buyers who need a different form factor or a higher voltage should look elsewhere.

Capacity and Voltage Match

The battery delivers 3000mAh at 3.7V, matching the nominal ratings of the original component. Supplier data also lists 3400mAh and 12.58Wh for reference, but the critical figures for compatibility are the 3000mAh capacity and 3.7V output. Confirm these values against the label on your existing cell before ordering.

Straightforward Swap With Adhesive

The pack measures 67.6 x 22.6 x 19.0mm and weighs 120.0g, fitting the internal cavity of the supported speakers. Installation requires opening the enclosure, disconnecting the old pack and connecting the new one in its place. The main risk is damaging the fragile ribbon cables or speaker drivers during disassembly; work slowly and use a plastic pry tool.
