being a ford customer's .if your car in under warranty and have your battery replace,then your warranty expire.but your battery has a three year warranty, ford on decatur will tell you that the warranty is not good and you have to buy a new one out of your pocket then they will warranty it.i took my battery to another ford company,and they replace it with no problem and no question ask.just a reminder,ford on decatur has very poor service and i will not tell my friends or my family  to go there.for me i will never take my car there for service a n y m o r e and that is a fact.they try to make money out of you...........
