why cant i charge my lg g7 newly replaced battery?

[Android Central Question]

Ive have been using my lg g7 thinq for over a year now and i started to notice my battery life being shorter in the last couple of months,so i decided to buy a new one and replace the original battery. I did that succesfully, i charged it up to 80% (when i first booted the phone with the new battery it was at 54%) and started using the phone with no problems at all. Last night, (a day after i replaced the battery) i was watching videos on youtube,listening to music etc when i noticed the battery level was at around 16%. A couple of minutes later it reached 15% and then the phone died,it didnt shut down, it was like the battery died. I pluged it in my wall outlet, the battery-notification light blinked,then the screen turned on but it showed 0%. I left it there to charge for like 15 minutes but it wasnt charging at all,the charging brick was cold and the screen still was black with 0% still showing.
What sould i do?

The battery may be defective.

Try charging for several hours.

Welcome to Android Central! Where did you get the battery from? Was it an OEM battery, or a 3rd party manufacturer? Can you ask them for a replacement?

Yeah I would call the place you bought it from and ask for replacement

And stop draining batteries below 45% (50% is actually the point at which you should charge, but if it reaches 45% and you can't charge, turn the phone off! Constantly draning the battery to 15% will kill it quickly, as you found out. (The battery should last 3-4 years, at least.)
