Battery, time to scrap?

I’m worried about my battery. I would like to know if I shouldn’t use it anymore. What is the limit of the battery? I don’t want to throw it away if I can do another 20+flights with regular checks ofc.! Right after flying three ventilation holes weren’t letting any light to pass. Unfortunately I didn’t take pictures instantly . Now it looks much better and it gives me hope I can still fly on this battery without issues. Voltages are ok (3.74; 3.72; 3.72; 3,74) 75cycles.
One and a half hour after flight all holes let some light pass.
