4bat/6/40000005 0x898c3590 error

Hi everyone,

I have a 2012 macbook air 13 inches intel i5 1.8Ghz 8GB RAM 128GB SSD.

Recently, I replaced its battery by myself by buying on Amazon and followed iFixit tutorials. It was pretty easy.

However, the mac alerts me that I need to replace the new battery soon! This doesn't make sense because this battery is new, so the battery is not the issue here?

I ran a diagnostics and the error is 4bat/6/40000005 0x898c3590.

I can't look up this code online, so can someone please let me know what this code means? Like error with battery, I/O board or cable?

Thank you
