Ordered this 2019 MacBook Pro 16 inch to use in critical client medical environment. I discovered (later after purchase) that the machine's battery had been replaced by SupremeDealsCR with a defective/intermittent battery SMP brand, prior to reselling the machine on Amazon.In 2024, a 2019 macbook pro battery should typically show a battery cycle count of between 300 - 500 cycles. The machbook that SupremeDealsCR sold to me on Amazon, shows a battery cycle count of only 16, which is impossible for an original factory installed battery. Which means SupremeDealsCR replaced it and did a very poor job in ensuring that the battery worked properly in the machine. It does NOT!The MacBook pro powers off totally on it's own, without any warning. When charging the MacBook, while on the desktop, it makes alarm sounding noises every 10 seconds (another red flag).Can you imagine being with in a medical environment, with critical patient care and have this type of problem? Well, I can't either.SupremeDealsCR you sold me a bad bill of goods and you knew what you did when you did it. Do not trust SupremeDealsCR seller!
