Why my New Battery won't charge?

Hi , i just bought from iFix it a brand new battery Truepower model APP6099 .

Out of the box the battery indicator showed a full range , so i've runned my macbook Pro model A1226 with the new battery without the power cable until the battery had no charge at all .

Then i plugged my power cable to run my mac and charge the new battery and as a surprise my baterry is not charging and the battery indicator on the top right side of OSX doesn't show any sign of a charging battery .

So i went to "More info" to check the battery status and the mac recognize it but doesn't start charginng it

So i did an SMC reset and still nothing happens ....

.....Help what's happening ? what do i have to do ?

Thanx
