Repair a Denon Heos go pack?

[T68]

Hi!
New member here.
Dunno if this is the proper place to ask but here we go:
I have a Denon Heos 1 network speaker where the rechargeable Go Pack no longer seems to charge properly.
It indicates full charge but won't power the speaker if I disconnected the power supply.

So I wonder if anyone tried to take a Go Pack apart and if it will contain a standard battery pack that can be replaced.

I new Go Pack is of course available but they are a bit pricey...

Thanks in advance for any input!

Hi,

It seems to me that this is a common issue with these battery backs.
I had one replaced during warranty and now it no longer charges.

Did you manage to fix the old battery?
