Why my Mac keeps turning off when unpluging power adapter?

1 Month ago I accidentaly sprayed some liquid on my mac’s keyboard then wiped it. Although I got it to the service, they fixed keyboard and etc. My mac shuts down when unpluging power adapter. I reseted the SMC, runned first aid and checked my battery life. I think that Mac’s battery cannot die after 6 months or is it the results of liquid?
