Does this mean the battery is not accessible for replacement once the battery has reached the end of it's rechargeable life?

Opened it up and there was no broken wires or anything. Tested the continuity and it was fine.

Then I checked the resistance and one of them showed around 22 ohms while the dead one was at 1000+ ohms. Which makes me believe the speaker itself is the issue. Note: I didn't disconnect the wires from the speakers when testing.

Is it possible to fix it? Can I replace it with speakers from an old headphone? Would I have to replace both? If I decide to buy a replacement, would it have to be the same impedance?

Thanks in advance
