How long do SUV and 4WD batteries last?

The battery of an SUV usually lasts three to five years. However, it is always a good idea to keep an eye on the performance of the vehicle and the battery after the three year mark. 

The weather also plays a part in the longevity of the battery as scorching heat will drain its life faster. Controlling corrosion, limiting short rides, keeping the battery tightly fastened to minimize vibration and turning off lights when exiting the vehicles are some of the maintenance measures that can be taken to maximize the lifespan of the battery.
