A guarantee is the promise that goods or services will perform as specified .
A Warrantee is a promise that the said goods will be replaced or made good
during a specified time from the date of purchase .
And in my experience in most instances either the goods will break down 1 day
after the Warrantee period is due , or there will be a clause written into the contract
specifying that because you were not a practising Lawyer at the time of purchase
it is now null and void , next time buy an Apple. 
warrant As you can see most contexts are synonymous with guarantee.
Warranty and guarantee = garantía (they mean the same)
Guarantee = garantizar
Well I think it would be a guarantee is a persons word that a product or service is or will be performed as specified. A warranty is a written guarantee that spells out what the protection will be on that product. Ianta, I am sure some better explanations will come along.
As a noun, they can essentially be used interchangeably.
The guarantee on the TV will last for four years.
Since it only cost a few more pesos, we bought the four year warranty along with the TV.
As nouns, I do think they that have a slight difference that many English speakers do not know. When someone says guarantee, I think it's for a lifetime. A warranty usually expires. Don't get too caught up in this, though. It's not like the English grammar police will come and arrest you if you mix this up. I see no difference, to be 100% honest.
Now as a verb, 'warranty' isn't used.
I guarantee that she will wear the red dress tonight. - Correct
I warranty that she will wear the red dress tonight. - Incorrect
Warranty is a noun, only. I think it usually refers to a legal contract.
Guarantee can be a verb or a noun. As a noun, it could be sombody's verbal assurance, and not necessarily a legal artifact.
