Can someone help me interpret this blink code?

Wasn’t this no battery thing an issue on older firmware version and they addressed it in later versions? I’ll see if I can find the one…

I only found the mention in the 3.06 BIOS (I feel like I’ve seen it for later ones though…):

There are other posts as well where this is brought up (They didn’t say what version they had…):

Linus also mentioned the issue in this video (And didn’t mention what version he had…):
