4/15    How often do people usually replace their car batteries?  My car
        battery died this morning even though I didn't leave any lights on.
        It's the original battery since I bought the car new in 1996.  Thx.
        \_ that's reasonable.  2-4 years perhaps, and if you drive short
           distances more than long distance, battery life can be shorter.
           Its time to get a new battery, though seeing if the battery
           can hold a charge can be a good idea if the battery is newer
           than, let's say, 3 years.
        \_ My car battery lasted for 7 years, and it died because my
           starter went all wonky.  I'm probably an anomaly. -geordan
        \_ It could be your alternator, too.  Never hurts to check.
        \_ Or distributor cap and rotor.
        \_ about every 7-10 years.
        \_ The deal should replace it for you ever three years or so.
        \_ The dealer should replace it for you ever three years or so.
        \_ 5 Years, typically... if you don't abuse it.  Then again,
           depend upon where you are.  I heard that battery last a bit
           longer in a colder climate.     someone flunked ChE176
                                           \_ not to mention E190.
        \_ i had a battery last 10 years in an old toyota truck. current
           audi will probably only make 5.  i blame the alarm etc. for
           sucking juice while the engine is off.
