Query: My laptop with this battery does not boot

I bought this battery and when I used it my laptop does not boot. To make my Toshiba Portege boot, I have to unplug it and turn it on with a external battery and then, after operating system starts, I then plug the battery back and it works... so, don't buy this product because it does not work correctly.
