    Why Buy A Battery for a Diesel Truck?

    • Maintain performance. Pairing your diesel truck with the wrong battery can limit the performance of your truck. It may not start after you leave it idle for a while, and gradually, your truck’s electrical system may get damaged. This means when you’re stuck in traffic, your truck may completely fail to start and leave you stranded.
    • Prepare for winter. Your battery is often pushed to its limits during a cold winter. The battery can also die if left inactive in freezing conditions. It’s no surprise that most batteries fail during the winter. Diesel truck batteries are designed to thrive in freezing temperatures thanks to their cold-cranking amps, which can power even the most stubborn trucks.
    • Replace your old battery. If you have a lead-acid battery, you need to replace it every seven years. However, that doesn’t mean that the battery won’t fail at any point even at its five-year mark. Replace your battery with one of the top truck batteries on the market since you don’t know when your battery may fail. 

    Types of Diesel Batteries

    Absorbable Gas Mat (AGM)

    AGM batteries have an electrolyte solution close to the metal plates for better discharge and recharge efficiency. They discharge at a slower rate than the other battery types. AGM batteries are considered a sustainable option since most of its parts are recyclable. The plastic shell, absorbent fiberglass, and lead-acid can be recycled. The only waste products are divider linings. 

    Lead Acid

    Most diesel batteries are lead-acid batteries. They include a mixture of acid and lead that stores an electric charge. There are wet cell and gel cell lead acid batteries. Wet cell batteries include a sealed option where the battery loses power when the electrolyte level drops. It also has a serviceable option that allows you to add distilled water to prolong the battery life. Gel cell batteries have an electrolyte suspended on a gel and are designed for hot environments.

    Diesel Truck Battery Pricing

    • Under $200: Expect to find mostly lead-acid starter batteries within this price range. Most units will deliver sufficient cranking power to start your truck in wintry conditions but may not be suitable for powering extra accessories. 
    • Over $200: This price range is mostly for batteries with higher cold-cranking amps. They are mostly deep cycle batteries that can maintain consistent voltage even after discharging for long periods. The high-end versions can have a life cycle that extends to more than eight years. 

    Key Features

    Cold Cranking Amps 

    The CCA is the number of amps put out by a battery at zero degrees for 30 seconds at a rate of 7.2 amps. A battery with a higher CCA is important for people living in regions where temperatures dip below zero degrees Fahrenheit. That's when it gets difficult to start an engine. Choose batteries with over 500 cold-cranking amps for such conditions. 

    Reserve Capacity

    The reserve capacity (RC) is a measure of the battery's running time with 2.5 amps of discharge. It helps you determine how many electronics you can run in your truck or what type of equipment you can charge before your battery runs out. AGM batteries have the best reserve capacity since they can maintain 80 percent of their charge even after deep discharge. 

    Size

    Shop for new batteries with respect to the year, make, and model of your vehicle. The new battery should ideally be the same size as your OEM battery. Also, the battery should never come in contact with the hood of your vehicle. It should leave a hood clearance of at least 3.4 inches to prevent fire hazards.

    Other Considerations

    • Life Cycle: This is the number of charges and discharges the battery can take before it loses its power (dies). Manufacturers often indicate the life cycle of their batteries, but it really depends on the conditions and rate of discharge. 
    • Compatibility: Be sure to select a battery that's compatible with your truck's engine and connection terminals. The connection terminals ensure that the battery is secured firmly in place to minimize vibrations when your truck is in motion.

    Tips

    • You can test the health of a battery by hooking it to a battery tester. It will show you the health of the battery based on the readout and load test. You can also use a multimeter checker to read the voltage of the battery when the truck is off or when it’s running. The readings should be 12 and 13 volts, respectively, for a healthy battery.
    • Maintain your battery at full charge to keep the electrolyte from freezing in cold temperatures. The electrolyte may freeze when temperatures dip below -16 degrees Fahrenheit. 
    • If you don’t plan on using your truck during the winter, consider purchasing a trickle charger. It will top off the battery every time it goes low and keep your battery from fully discharging and dying.
    • When jump-starting your diesel battery, turn on the heater to protect your truck’s electrical system from surges in voltage. Also, disable the lights and other electrical accessories that may drain your battery and make your work more difficult.

    FAQs

    Q: What are the signs of a bad battery?

    A: The first obvious sign of a bad or dying battery is a vehicle that won’t start. Also, your vehicle may crank slower, and there may be sporadic sparks in the battery cylinders that may cause your truck to backfire. Moreover, you may notice that your headlights are dimmer since the failing battery can’t power your car’s electrical components.

    Q: How many batteries does a diesel truck run on?

    A: A diesel truck can run on one oversized battery, but since it’s a bit challenging to find an oversized aftermarket replacement, most people use two batteries. A diesel engine requires more cranking amps to start than a gas-powered engine. It, therefore, needs two batteries hooked up in a parallel connection to keep the voltage constant and to increase the current rating that delivers sufficient power to turn a diesel engine over.

    Q: Can a gasoline-powered vehicle jumpstart a diesel battery?

    A: It is possible for a gasoline-powered vehicle to jump-start the diesel battery and the other way around. The process may take longer if the battery level is really low or dead. If you manage to get a full charge but experience the same problem the next time you try to start your truck, then you may have a defective battery and need to buy a new one.
