Need some help please. I have an 03 Viper and am having difficulty removing the battery panel in the trunk. The cover only has two screws remaining, so it appears that the previous owner had some problems removing the panel. The tops of the two remaining screws are stripped. Is there a special technique for removing battery panel screws? The manual does not indicate that there is any technique for removal. Trying to give the battery a charge before storing. Also, can the battery be charged without removing the panel, i.e., from the post in the engine bay? Any advise would be appreciated.
