If this is the original Pixel I'm not surprised that the battery didn't last long.
I had to do a web search to find out what HSABAT is, and what I found was an ultra-cheap AliExpress seller who is claiming to sell batteries with almost double the capacity of the original one for $9. And I have to say that "80% more capacity in the same size for almost nothing" is a real red flag for me, and I'd not be at all surprised if what you get is a low-quality piece of junk that doesn't actually match the specification. The fact that the small print on a "4,900 mAh" battery says "capacity 3,500-5,000 mAh", a 40% variation in capacity between samples, is frankly an admission that quality control is very poor.
So it may be that there is some other problem, but it's also possible that you've replaced a dead battery with a crap one.
