Selecting the Right Commercial Vehicle Battery: 8 Essential Considerations

When you’re responsible for managing an entire fleet of vehicles, the task of choosing a commercial vehicle battery takes on a different set of considerations compared to selecting a battery for your personal car. Your fleet requires commercial batteries that not only fit within your company’s budget for parts and maintenance but also offer unwavering reliability for the various drivers using each vehicle daily.

As you embark on the journey of shopping for commercial vehicle batteries, it’s crucial to look beyond the price tag. Focus on these eight critical factors to ensure you make the right choice for your fleet:

How Commercial Vehicle Batteries Differ

Commercial vehicle batteries are purpose-built for distinct performance requirements. Unlike personal vehicles that see daily use, commercial vehicles may need to start heavy semi-trucks or power boats for extended periods. They might travel long distances regularly or sit idle for extended periods, depending on your business. These varying usage patterns mean that commercial batteries differ significantly from those designed for personal cars.

Commercial batteries often feature larger and thicker lead plates to provide increased power. Vehicles with sleeper cabs or numerous electrical accessories require batteries capable of handling these higher power demands. Consequently, commercial batteries tend to be larger and heavier than their counterparts for personal vehicles, due to the need for larger plates to supply power to larger vehicles equipped with a broader range of electrical accessories.

Selecting the Right Commercial Vehicle Battery

Managing a fleet of vehicles entails a great deal of responsibility. Ensuring your vehicles remain safe and ready to perform for both drivers and customers requires batteries that can deliver the appropriate power levels. You’ll also need to weigh additional factors such as safety features and performance in extreme weather conditions to maintain smooth vehicle operation.

When it’s time to replace a battery in a commercial vehicle, consider the following factors:

  • Power: The power requirements of commercial vehicles can vary significantly. Are you managing a fleet of small trucks or rental cars, or do you need a battery for a heavy-duty semi-truck? The required power level will dictate the type of commercial vehicle battery you should choose. Common commercial battery types include:
    • Flooded lead-acid batteries: Ideal for vehicles like day cabs of semi-trucks and heavy-duty vehicles that need a strong initial energy burst or make frequent stops.
    • Absorbent glass mat (AGM) batteries: Popular in newer vehicles and those equipped with energy-demanding accessories, such as sleeper cabs with additional lighting and cooking equipment. AGM batteries are also suitable for marine use due to their solid-state electrolyte.
  • Vehicle Type: The battery you select should match the vehicle’s specifications. If a vehicle originally comes with a commercial AGM battery, it’s best not to replace it with a flooded lead-acid battery. Some vehicles with flooded lead-acid batteries can be upgraded to AGM batteries, but always consult the vehicle manual for voltage and mounting instructions to ensure compatibility.
  • Cost: Managing multiple vehicles means battery purchases can add up. While flooded lead-acid batteries often have lower initial costs compared to AGM batteries, AGM batteries can last two to three times longer, potentially saving money in the long run.
  • Lifespan: Battery longevity isn’t just about total lifetime cost; it impacts vehicle downtime. In a commercial setting, time is money. Consider that flooded lead-acid batteries typically start a vehicle engine around 30,000 times, while AGM batteries can handle around 60,000 starts.
  • Maintenance: Battery maintenance can affect fleet productivity. Flooded lead-acid batteries usually require more maintenance, with the electrolyte needing regular refilling, based on vehicle usage.
  • Weather: Commercial vehicle batteries can be sensitive to temperature extremes. Look for batteries with thermal protection and check the Cold Cranking Amps (CCA) rating to ensure reliable starting in cold temperatures.
  • Safety: Proper battery maintenance and handling are crucial for fleet safety. AGM batteries, with their solid-state electrolyte, are less likely to spill and can better withstand vibrations.
  • Warranty: A warranty provides peace of mind, especially for batteries that may underperform or fail prematurely. Many commercial vehicle batteries come with one-year warranties due to the wear and tear they endure. Longer warranties may offer extended protection but could impact the battery’s initial cost.
