I recently have this issue where the check battery light flickers on and off for a few secs and it feels like the car is losing power but its only momentary. Got the car checked and I have a brand new battery and they said its not my alternator. Any ideas as to what it could be? P.s not sure if this is related but my 12v ports stopped working around the same time.
loose alternator belt, check battery connections too, for tightness
