Battery will not charge even after replacing

I read this guide in January 2015 and ordered a battery. Easy to replace, BUT, the battery would not charge. Ordered a second battery, same, battery would not charge giving a question mark in the battery icon. My Droid 4 became a brick I have spent the past 2 months trying to get it to work again. Ordered a Factory Motorola USB cable with a pin shorted. When plugged into my PC the phone boots and I can use it, BUT, the battery WILL NOT CHARGE. I can find nothing on the internet to solve this problem. I cannot carry my laptop around so that I can use my phone. SOMEONE PLEASE HELP!
