OK. My battery died the other day. It started well today, and then I had the dome lights on (but not even accessory on) for 20 minutes while I was changing a piece of the dash, and it lost its charge. So I'm going to buy a new battery. Any suggestions as to brand, or the basics of what size or quality? I don't want to get trash, as I want this to be as reliable as Maximas should be, but if Walmart is good enough then that's fine with me. Recommendations, please? Thanks a lot!
