Not a new subject here but one I need some info about. Pls bear w/me. I need to replace the battery in RR. The Optima brand batteries are popular among your group and i'd like to install either an Optima D31A Yellow top or a D31M Blue top for their deep cycle advantages. Yet I have found that battery product search engines indicate that neither of these batteries will fit. But the compartment space appears adequate and other model years can accept these battery sizes. Will they fit in my 2004 RR HSE?
? #2 Any precautions on that incendiary positive battery lead? I have disconnected the negative lead to recharge the existing battery but have not ever pulled the positive lead.
? #3 The open hood access to the rear battery compartment is tight. Can the hood be opened any wider without fully removing the thing?
