The alternator recharges the battery and supplies power for the entire vehicle while it is running. The life expectancy depends on how it is used, I have seen some alternators run over 200000 miles while others have failed within factory warranty. Cost to replace an alternator varies greatly, I have done some that only took a half an hour to replace while other have required the engine to be removed to even get to the shielding that covered the alternator. .
They are right, the alternator can die at any time or last many years. The working part of the alternator is diodes that can get dirty and fail. Most of the time a thorough cleaning can rejuvenate the alternator if there is no physical damage.
