Why new battery is stuck at 63% charge?

I have a mid 2007 macbook that works great.

i’ve installed a new battery and i’m using a new magsafe charger (both not OEM). I see that the charge is stuck at 63% and the magsafe’s light is orange for a couple of minutes and then turns green. the leds on the battery all light up meaning, apparently, that the battery is fully charged.

Could it be that the battery is ok and the problem is that the battery doesn’t communicate well with the OS and that’s why the OS thinks the charge is 63%?

the first time i used the battery and charger i got a 100% charge according to OS X.

i’ve already tried SMC reset with no success. could the problem be fixed by totally draining the battery?

first of all thanks. the screenshots:

Well i decided to try by draining all the charge of the battery. i did it and then when recharging it stuck at 57%. faulty battey maybe? then i decided that in the meantime i buy another battery i would use the one i have so i left it charging like a day or so without using the macbook too much. the light was green.

today i saw the battery percentage indicator and says 100% charged. strange. i unplugged the magsafe and used the machine normally. went down to 92%. i plugged the charger again and started charging like normally would do, but instead of showing 93% and up, now it tells me its charging and that it has 74% charge. i believe it is a faulty battery that is causing all this.
