My MacBook only charge with low watt charger

I changed the battery for one purchased at ifixit, I completed the entire change process without any problem following the steps in the tutorial. I connected the computer initially to a 5w iphone charger to protect the SMC, then perform the battery calibration process, charge to 100% then use the pc until the battery runs out, then charge to 100%. After performing the calibration, the computer does not charge with the original charger and only charges the battery with the 5w charger. Has anyone had this problem? Is it a battery problem? Is there any way to solve it?
