The battery should work fine... And I actually got one without a vent hose and its been working just fine going on 2 years now...Also. You do not need a radio code..That idiot at wal mart has no idea what he's talking about..these aren't Acura's...

In my opinion..leave wal mart out of it...Go to autozone or advanced auto parts, or an auto parts store.....get your battery there..
