I bought my car used so as far as I know it still has the factory battery, 3 years and 31,000 miles. Although last time I took my car in the dealership they told me my battery was going out, we will see.
With that, batteries on average will have a life span of 3-5 years but that is with general day to day use. Factors like harsh conditions, extreme cold and hot cycles, abusive usage, and whatever else you can throw at a battery will shorten its life span. Some batteries also last longer then their average life span, so you may have one last 7 years or longer. On the other end you may have a battery that will only a last a year or so, no bueno. The type and grade of battery you buy also plays a roll in its life span.
So you cant really go by what every one else's battery is doing. You just have to take care of it, do whatever maintenance is necessary, and have it tested if you feel it maybe going out.
