When my battery died I stopped at Autozone and they would not change my battery. Said they couldn't do it, said they didn't know what the small square thing was on the side of the battery. It is pretty obvious it is a vent. They also said there were to many wires connected to the posts. Everything is stock but air cleaners on car. Then they asked if I was there 3 hours ago. I said no and they said that a car identical to mine was there earlier. Last Month my Sister said she saw my car at a store parking lot, but it wasn't me. I have only seen a red convertible in town so far. Mine is a graphite grey color.
Went to Advance auto parts and they put a new battery in the car in under 10 minutes. They were 14 bucks cheaper also, and were a lot more knowledgeable. They also took a lot of care not to hurt the paint.
