I noticed something different about the battery in the 2015 LR4. It has an extra wire. There's a wire in a black plastic flex conduit with a red angled jack connector. It sticks into the side at the top of the battery. This makes me wonder if, when it comes time to replace the battery, i'll need to find a battery that supports this odd feature.
I'm afraid to disconnect the wire for fear it services something important like the vehicle security system or the stop/start system. I haven't found anything on google about this, but that's because the things you'd search for (battery wire red top) will generate a ton of results that are not about this.
