Query: DO NOT BUY! DEFECTIVE BATTERIES!

I bought one pink battery. I connected the battery to the charger and right away it said it was charged, I removed the charger and the battery went dead, I contacted the seller for this item and they sent me a replacement battery the SECOND battery did the exact same thing! none of these batteries work I bet! You guys will lose many customers with these products. THANKS FOR NOTHING now I have to have my controller connected to a cable all the time! >:(
