Does anyone know if I can use the he 450 bt replacement battery in a 350 bt headphone? The difference in the spec is that the 450’s battery has a longer battery life (2.2 wh vs. 1.3 wh)

This was pretty straightforward, but in opening the cap one of the tiny soldered wires pulled off the pad. It's so tiny that I don't have much hope of soldering it back. Any other way to reattach it? I put it back together anyways and now the right cup works fine, but the left is dead. I recommend a warning here about the little wires, if nothing else.
