-battery wouldn't charge at all
-no light would come up on the charger at all
-battery still held charge and would show it
-no tool would work on it
-adaptor with usb ports would work normally
-to test if thermistor is the issue, perform below test with multimeter:

Check the voltage of the battery measuring from the B+ to B- terminals.

Thermistor check #1 Measure the voltage from B- to TH, you should get the same voltage as the B+ to B- measurement.

Thermistor check #2 Measure the  Resistance (Ohms) from B+ to TH, it should be around 12k
