blackjack ii battery charger

BlackJack II will not be responsible?
Blackjacks My battery is completely dead. I plugged in the charger and not loaded. I died trying restarting, but now will not turn back. Someone knows what to do?
Bring your phone to your local AT & T. Request a new post of the battery on your phone. See if it takes over. If you do not need that large of a new battery. If not, then this is the phone itself. You can exchange warranty phone if it's still under warranty.
