Problem Huawei battery problem


Hello, I had a huawei y6 that I stored for a period of 1-2 months with a charged battery, but when I checked it, it wouldn't turn on and the battery was swollen..
I ordered a new battery from a website of ours, I installed it without any problem following a tutorial on YouTube, but although everything went ok and it was really simple to change.. the phone refuses to start with the new battery.. I kept it charged for 24 hours with the charger and a few hours with the laptop but without result.
What can i do ? Is there any method by which I can force the battery to charge? Or is the battery too old and should I take it back to the store where I got it?
