If that would be the case, can someone please explain to me how this registering works? Do I need to purchase this Carly software and OBDII? Do they provide this service at AutoZone/Oreilys etc ?
Something else is wrong, not registering the battery wouldn't cause it to be completely dead. Recheck everything!
