I recently purchased a used 2011 Range Rover HSE. I need to change the battery since it is the Original battery and has died. I purchased a Sears Diehard AGM Gold battery (Plate Type battery with 850 CCA (OEM had 800 CCA). I disconnected the battery terminals as well as the 2 long hold down screws. The problem I'm having is that I am unable to pull the battery out of the battery compartment. In front of the battery is some sort of computer with a fan, so I can't remove the battery that way thru the front. I also can't pull it straight up towards the windshield because of the overhang of the plastic windshield surround. So i think the only way to remove the battery is either to remove the computer in front of the battery or the remove the plastic windshield surround above the battery and pull it straight up. One other question is that I read something about a "RESET" to something after a battery change, not sure what that means. If anyone has some insight on these two things via a link of tutorial, that would be great too. Please help. Thanks in advance.
