Okay so I have to share this because I've been stressing about my car battery for the past two weeks, replacing terminals, cleaning connections, even took it to two different garages who both told me everything was fine, and it turns out the problem was literally just me being an idiot. I have this little dash cam that plugs into the cigarette lighter, and apparently even when the car is off and the key is out, that port on my particular model stays live and was slowly draining the battery over a few days. I never even thought about it because in my old car the lighter socket would cut power when you turned the engine off, so I just assumed it was the same here. I only realized what was happening when I happened to glance at the camera's little red light still blinking at like 2 in the morning while I was grabbing something from the car. I felt so relieved but also so stupid at the same time because I spent money on diagnostic tests that I didn't even need. I started reading up on other common drain sources just to make sure there wasn't anything else I was missing, and I came across this resource (https://batteryzoneuae.com/) that listed all the usual culprits like glove box lights, trunk lights, and even the radio memory function drawing more power than it should. Anyway, I unplugged the camera and now the car starts perfectly every time, no issues at all. Just wanted to post this in case anyone else is going through the same frustration and hasn't checked their accessory ports yet, because I wish someone had told me this before I wasted all that time and cash. Has anyone else had a similar experience with something seemingly harmless causing battery drain?
