XDP carries industry leading manufacturers such as Odyssey Battery, and more! There are various indicators that your truck's battery is deteriorating and needs to be changed. Sluggish engine cranking or dim or flickering headlights are often symptoms of a weak battery. The average life expectancy of a battery is typically between three to six years. Even under the most ideal conditions, chemical reactions cause batteries to slowly break down. Dual batteries were offered on some heavy-duty diesel trucks. If your truck has two batteries, it's always a good idea to replace them both at the same time.
