I have a Dell DLA3000RM2U that I need to replace the RBC43 battery. I have removed the 3 screws in the front of the unit and the battery will not budge and come out. I have an APC SUA3000RM2U that is supposed to be the same unit and the battery swap on that was a breeze. The battery unit doesn't look like there are any other screws than the 3 in the front.
Any help or advice would be greatly appreciated.
