Manufacturer's Warranty - How long does it last?

About three months ago, I had to get a charger replaced because it stopped working properly.  At that point, the Complete Care Warranty was still in effect.

However, recently the replacement charger has stopped working as well.  Since the Complete Care Warranty is now expired, I was wondering if Dell would still replace the charger again when it lasted an even shorter time than my last one (which, by the way, lasted about 3 or 4 years)?
