BB Torch :: 9800 Not Holding Charge And Rebooting Constantly?

My BB Torch 9800 on my AT&T network is constantly not holding any battery charge, it's constantly dying on me even though I constantly have in plugged into a car charger or a wall charger at all times, it also started to reboot itself and then once its complete it reboots itself again and again and again. I've tried leaving the battery out for 15min and then trying to reboot it again, that does nothing. I've gone into the Options section under Device and disables the Compression, that did nothing, I've check the CPU Usage for the day and the week nothing is really eating the power up. I have also held down the menu button and switched off all my apps in there and still no better.
