If I am replacing the alternator on my truck what is the likely hood that my battery will have to be replaced as well?

Battery is the reservoir for electricity, alternator is what tops it up to maintain voltage. A bad alternator that over charges a battery can buckle the "plates" in the battery. A battery that won't hold a charge can cause an alternator failure. Have the battery charged and tested before condemning it.
