Need help R53 won't start.
Hello, guys I got a pretty weird issue going on. My 2004 R53 won't start. I will link a youtube short that I made since I can't explain how weird the situation is. Maybe is a faulty battery? I don't have the battery light on in my dash. It started doing that today; the mileage of the car is 128,397. It's a 2004 Mini Cooper S r53. (EDIT). I was at a gas station at 10 of the night I was able to turn on the car after I stopped the video.

Everything is tight, and there is no Corrosion. I went to a place specializing in batteries to get my battery tested, and they told me the battery was good and has no problems. I had to drop the battery there in the morning since it was a bit low, 12.3V instead of 12.6V. They let me borrow a battery in the meantime. With the borrowed battery, the car turned on the first try, and once I got my original battery back (fully charged), it also turned on the first time. They also tested my alternator and underload the alternator still pumps 14 Amps. The worker who attended me told me it might be a starter issue.

my Mini is the only car I own
How many tools and parts do you carry? Only correct answer: all of them!
November 2019, so not that old, but not old enough that needs to be replaced.

Besides having the heaviest wheels (S-Lites) on the car I am also weighted down with 60lbs of tools and parts. Pretty much prepared for most unfortunate of circumstances.
It is a habit I learned from owning and driving aircooled for almost 40years.
Some may say I'm paranoid. I prefer the term - "overly prepared"

Had a very similar situation last weekend. Hopped in the car for a test drive. Turned the key - gauges came on and FP energized. One more click to start and ……. Nothing. No more lights. No more gauges. Nothing.
crawled through the back to check battery voltage. Good there. Grabbed the wires to make sure they were tight and to my surprise the ground was loose enough to turn. New battery in July was all good with nice tight clamps. Here in January, I’m thinking the metals contracted just enough to cause poor contact (single digit nights).
cleaned everything and re tightened. Car fired right up. Check and clean both sides of the battery. Like Adam said, check the ground strap. Make sure you have the same voltage at the pos battery terminal in the engine bay as you have in the boot. Then check fuses in the engine bay for continuity
After all of that I would start thinking about the ignition switch

This will be my 3rd-year ownership of an R53. I love the car a lot, but I'm planning on selling it and getting an Audi A5 B8 Quattro (an all-season car and I'm a Euro car fan.). I live in Washington, so the snow here is no question. I'm going to move to Seattle to study, and I would like to visit family during Christmas. I will need to cross the mountain, and I don't think the mini will be capable of doing that in the middle of winter. Before selling it, I want to change the supercharger oil and fix my coolant leak, but besides that, not major stuff has happened besides changing some leaky power steering likes, which were a pain in the but to change
