After replacing battery doesn't even start.

Sorry for my language, i'm not native speaker.

Hello everyone, i have iPhone 3gs. After replacing battery to not original (Palmexx now i don't have any battery besides this), phone doesn't turn on, itunes see it in recovery mode, but screen even doesn't blink. I can restore it, but in the end i have error 29. I've checked motherboard and didn't noticed any damage or any problem with tails (i hope i chose right word). When connected to the PC it gets warm. Again sorry for my language, and i wanted to ask if this problem becouse of the bad battery or becouse some other part of the phone was damaged?
