How should you periodically inspect and replace battery cables to ensure proper engine performance on 2003 Mazda Protege?

Check all battery cables periodically to identify any damage, fractured insulation and corrosion, because inappropriate connection may cause starting issues. Test check cable-to-terminal connections (checked against cracking and corrosion). Always leave the negative cable disconnected and lastly connect it. Make clean connections and add corrosion inhibitor then firmly snap on new cables.
