What is the longest an electric battery for a car can last?

    Most car batteries will not last more than 5 years, though depending on your driving habits, it is possible for a battery to last slightly longer than that.  There are three main factors that can shorten the life of your car battery.  The more times you start your car, the more you are depleting the battery.  This does not have a huge effect on the length of the life of your battery unless you tie another factor in with it… the duration of your average trip.  If you start your car and drive less than 20 minutes, your alternator will not have the chance to totally recharge.  The last main factor is the weather.  Cold weather alters the chemical reaction that your battery produces so people living in colder climates should expect their batteries to die a bit sooner on average.
