My laptop battery took so long to be charged and it run out of battery too fast.

Hi ~
Please help me. I've replaced my old and original battery and buy a new non-original one. It was efficient till last month. I've bought the new one around 4 months ago. The status is (plugged in, charging) yet it took so long to increase in percentage. Before this, I've encountered the problem of (plugged in, not charging) but it was solved. Now, my laptop battery took so long to increase in percentage yet it run out of battery so fast.

Unfortunately, the most likely answer is that the non-original one is knockoff trash. Did it come with a warranty?
