Asus laptop battery charges slowly, then suddenly went up to 100%

I just bought a new battery for my asus x450j. the battery indicator turned green after i charge it for 1 hour. When i turn on my laptop it turns out the battery was only at 58%, and the indicator went red again. i unplugged the charger to let it go down at 55% then plug it on again. It charged very slowly. After 58%, suddenly it went to 100%. But if i unplug the charger, it went back to 58%, and will go up to 100% again if i do the same thing.

Is this the battery problem?

Sounds like a bad battery to me. I would exchange it, or if it is an aftermarket one, they can be kind of hit and miss, I would return it and get an OEM one.

Sounds like a a battery problem. I'd get a replacement.

i got a replacement, but still the same. Even the replacement only reached 48%.
Should bring this to a service centre? I'm afraid the problem is actually on my laptop.

It may well be. Unfortunately.

I would initially think its a bad battery, is it a 3rd party one? Also do you have some sort of battery saver option on? I know on some of the laptops I own, you can set your comp to only charge up to a certain percentage, might want to check that. Could also be a bad brick on your charger? Generally when a battery charges super fast it means the batter is on it's last legs.
