OEM batteries has an average life span of between 3 to 5 years, but there are several factors that also changes this projection. Lead acid batteries like being full, meaning if you drive at least 20 minutes almost every time you crank it over, chances are it stays fully charged, if less, then you are subtracting months off battery life. If your battery had ever drained to a point where you have to jump start it, you are also taking a few months off. Under the best scenario, which is to keep the battery charged, and also check the level of the battery acid on a monthly basis, I had encountered an Interstate battery that lasted almost 6 years before the battery voltage went down to 12.3V, rendering replacement.
