A truck’s starting system relies on its battery. This component delivers electrical power to the starter, which cranks the engine. The battery also provides power to the lights, radio, Global Positioning System (GPS), lift gates, and other electrical components. If the unit fails, you may require towing to secure battery repairs, recharging, or replacement. The guide below provides an overview of how to care for a few common types of batteries to help you avoid maintenance problems.

A Trucker’s Guide to Battery Maintenance

1. Flooded

Flooded batteries are some of the most widely used in trucks, powering everything from day cabs to dump trucks. Though inexpensive, they require more maintenance than other batteries.

Once per month, add distilled water to the unit to prevent its acids from corroding the terminals. If you spot any corrosion while refilling the battery, use a toothbrush to clean the terminals with a mixture of baking soda and hot water.

2. Cycle

Trucks that require multiple electrical loads and frequent cycling need stronger batteries. They’re often found in sleeper cabs, delivery trucks, and vehicles with lift gates since these trucks work for long hours. Flooded cycle service batteries provide enough power to start large engines while simultaneously supporting accessories and anti-idling systems.

Much like flooded batteries, cycle models require monthly cleaning of the terminals for optimal performance in the long run.

3. AGM

towingAbsorbed Glass Mat (AGM) varieties offer maximum starting and cycling power. Since they use glass mats to absorb electrolytes, they are high-performing, long-lasting, and more durable in the face of vehicle vibrations. They’re often used in heavy-duty trucks, such as reefer, line haul, mixer vehicles.

Since undercharging and overcharging may decrease the life span of these batteries, consult the manufacturer’s recommendations before charging them. Follow all instructions to provide the right voltage.
