How to access internals of Seiki smart speaker

[rbm]

Friend of mine has an obscure portable smart speaker branded as Seiki.  The internal battery has reached end of life and won't hold a charge very long so he wants to replace it if possible.  There is no obvious way to get at the internals.  The speaker is covered in what looks like a rubber material to make it water resistant and there are no access panels to remove.  There's also no information online about this speaker so no parts diagrams or user manual.

How is it possible to get access to the battery?

I don't know about this specific model, but most wireless speakers are not designed for easy disassembly and battery replacement, as some parts are glued together. Especially "water-proof" ones.

However, repair is still possible, as internals are very simple. I would start by carefully removing grills from speakers - there could be some screws under them holding speakers. With speakers removed you have access to PCB.

Any hope of a friendly dentist or vet that could do an xray of suspect area (under control membrane or near speaker grill) for holders or hidden screws?
Friend of mine saved my butt several time taking apart small stuff like a computer mouse avoiding undue damage.

Is there an FCC ID on the unit? If so, the FCC web site may have internal photos.
