Battery or the charger

I just bought 2 new batteries for my Stiletto 2, the original was damaged. But when I try to charge both of them they stop at 22% ( the first one I tried)and 29% charged(the second one). Is this the battery, did I get crap ones or is it the charger having difficulties?

I have tried charging both of them for over 24 hrs each and they don't go beyond that.
