How Long Do Semi Truck Batteries Usually Last?

Semi truck batteries are essential components of long-haul commercial trucks. They provide power to engine starters, lights, and other electrical systems in the vehicle.

Semi truck batteries last for a long time, but how long exactly? Depending on its type and quality, a semi truck battery can last anywhere from two to five years.

Factors that Affect Battery Life

The life of a semi truck battery is determined by several factors. First, the type of semi truck battery used plays an important role.

There are four types of semi truck batteries: AGM (Absorbed Glass Mat), Gel Cell, Lead Acid, and Lithium-Ion. Each type has its own advantages and disadvantages when it comes to battery life.

The second factor is the quality of the battery itself. Low-quality batteries can have shorter lifespans than high-quality ones.

Thirdly, the environment in which the semi truck battery is used can have a significant impact on its life expectancy. For example, extreme temperatures or frequent vibrations can reduce the lifespan of a battery.

Maintenance Tips

To maximize their lifespan and performance, semi truck batteries should be inspected regularly for signs of wear and tear. Batteries should be cleaned regularly with a solution of baking soda and water to remove any debris or corrosion that may have accumulated over time. It is also important to keep terminals clean and free from corrosion buildup.


With proper maintenance and regular inspections, semi truck batteries can last between two to five years depending on their type and quality. To ensure optimal performance and longevity, it is important to maintain your semi truck battery regularly by cleaning it with a baking soda solution and keeping terminals free from corrosion buildup.
