Dell XPS 7590 new battery blinking amber light
XPS 15 7590
Hello. While doing an overhaul of my laptop I wanted to replace my battery since it was 49% worn out. I ordered a new battery from a store that should be compatible. I'm very unsure about it being original (most likely not, like 99% of the original batteries on the internet) but people do buy them from that store and they work properly.
So the issue is, my old battery charges properly and everything, just that from 55wh only 28 are left. The new battery is 97wh. If charged above 40% charges and works properly. No faults, no wear, tested on 100% cpu/gpu load. However, should I discharge it below 35-40% the laptop refuses to charge it. It blinks 4 amber and 1 white (no such code in Dell xps light code section).
The AC is genuine 130w and it is recognized, it charges the old battery perfectly.
Even when blinking F12 diagnostics says everything is okay (lol). BIOS says IDLE. In Windows it says plugged in, not charging.
After plugging and unplugging it for 10 minutes it began to charge and then even if you disconnect and reconnect the charger no more amber light.
The old battery consumes 15w of power on charge while the new one takes 35w (when above 40%). Also I noticed the voltage on old one being higher when almost discharged 11.1V vs 10.9V but that little difference shouldn't matter, I think.
Yes, I already hard reset bios, taken out cmos bat, deleted drivers and did everything I could find on the internet besides plugging the battery into motherboard while the latter is being powered by AC.
P.S. I returned the battery thinking it's faulty, got a new one. Absolutely the same behaviour. I refuse to believe it's a battery fault since the old one I took out looks more of a copy than the new one but works.
Any other advice I could try besides "replace motherboard" or "buy genuine dell battery" that's not available at my place? Thanks in advance.

4 amber 1 white means a faulty battery. And OEM batteries are still available

Your call - replace the battery or the mainboard, but I'd start with the battery. The issue sounds very much like a pair of incompatible third-party batteries.

@ejn63 this "faulty battery" only happens when below 40% of capacity. When its more then no blinking whatsoever. I mean the laptop is supposed to tell you the battery isn't supported if that's the case. If it was faulty it wouldn't only blink on lower half of capacity. The battery was tested both times before being shipped to me on another laptop. And while the website you posted does have them, they don't deliver to my country and even if they did, delivery would cost another 100.

Okay, it was indeed apparently a fake dell battery. Today got an original 6GTPY one and it safely discharged to 30% and started charging. Got another question now. With the original 130w charger at 30% capacity it started charging at a whopping 82w of power, the coolers started blowing loudly even though the system was idle. Then when it charged to 35% the power dropped to 42w. Is it a normal behavior to charge at above 80w? I'd think its not since that's like 7A of current and if we take out the idle 10w it's like 6A to charge the battery, roughly. The palmrest on the left side became very hot, almost unbearable to keep my hand on it.
