These days, you could find your battery in the trunk or even behind a wheel well so, as usual, we recommend you consult your service manual before you get into this. A top post battery was used in this job. If your vehicle has a side terminal battery, the steps will be much the same. Side terminal batteries do not have top posts. The terminals are molded into the side wall of the battery and they use a different style of battery cable end. And if you find installing a new battery is going to be more complicated than you thought, we’d be happy to recommend a professional technician in your area.
