Are there aftermarket batteries available at any auto parts stores Sam's wal-Mart, Sears, auto Zone, Pep Boys, etc. that have a battery for this vehicle? O haven't priced one at the local Hyundai dealer but I am sure that with Hyundai's name on it from the local dealer that ir will be at least 0 or 0 for a battery. Is there any reason (computer operation, terminal placement or sizes), that would keep me from taking the physical size to an auto parts store and getting a battery for it. Thanks in advance.
