Removed a 18650 battery from my solar light while it was on to do a test and when put back in nothing is working, not sure what’s going on. Has the circuit board been damaged??

 

hi Age,
Welcome to AAC.
Is the battery installed the correct way around.?
Check the battery voltage, when its out of the board and when it is in the board.
Post the values that you measure.
A photo of the board would help.

Yes installed the correct the right way around, will do some checks tomorrow, and will let you know.
