Curious, nothing to lose I took the case apart and found the black component arrowed

open circuit it is the main connection between battery pack and circuit board, Battery measures full voltage before this device.
It's Klixton 10v9K 4MM70B1
this seems to be a thermal/current breaker
So anyone know were I could find a replacement,[1]
If I can't find the correct replacement part I am considering replacing with

Sometimes, the safety mechanisms built into the onboard processor
won't let the battery turn back on. You can't fix this by normal means.
Would be a shame to go to all the trouble to replace the open device and find that the pack still won't come back alive.
While such devices sometimes fail spontaneously, it's likely
that something caused the failure. Without fixing the root cause,
you're likely to be right back into the same problem again.
Note that for some batteries that look like yours, you can't get any
volts out the end contacts until the top two contacts are bridged by
a jumper in the laptop. You probably have to check for volts between
one of the top contacts and one end contact.
In summary,
You should NEVER, EVER safely and temporarily substitute anything!!!
You should always follow the manufacturer's recommendations, which
state, in part, DON'T disassemble it.
I'm no lawyer, but I am afraid of them... ;-)
