Hey guys! I currently have your standard wet cell battery up front and a XS Power D680 in the trunk. I've heard all over the place it's really bad to mix battery types so depending on the size of my next paycheck I'm gonna pick up or order a new battery. My car is a 2001 Lincoln Continental. What does everyone suggest? It doesn't have to be crazy powerful, also don't wanna sacrifice my left nut to pay for it.
