How long do truck batteries last?

Truck batteries are an essential component of any commercial vehicle, powering the engine and other electrical systems required for safe and efficient operation. Like any other battery, they have a limited lifespan and will eventually need to be replaced. But sometimes it’s nice to know just how long that could be, right?

In this blog, we will take a good look at how long truck batteries typically last, as well as some of the factors that may affect their lifespan.

How long do truck batteries usually last?

The lifespan of a truck battery can vary widely. This will depend on several factors, including the type of battery, the quality of the battery, and the conditions under which it is used.

Typically, a truck battery will last between three and five years, although some may last up to seven years or more. However, this is just an estimate, and the actual lifespan of a battery will depend on several factors, which we'll discuss below.

The type of truck battery you have

Some of the most common types of batteries used in trucks are lead-acid batteries, which are well-known for their quality and lifespan in the trucking industry. They’re durable and reliable. There are many kinds of lead-acid batteries, including flooded lead-acid batteries, absorbed glass mat (AGM) batteries, and gel batteries.

AGM batteries are often considered to be the most durable and longest-lasting and can last up to seven years or more, while gel batteries typically last between five and seven years. Flooded lead-acid batteries, on the other hand, will usually have a shorter lifespan of three to five years.

The quality of your truck battery

The quality of the battery can also have a big impact on its lifespan. Higher-quality batteries are usually made with better materials, are better constructed, and are built to withstand harsh conditions.

Cheaper batteries may save you some money upfront, but they may not last as long, which means you'll end up spending more money in the long run.

The conditions in which your truck battery is used

The conditions in which your truck is used can also impact the lifespan of the battery. Extreme temperatures, both hot and cold, can cause a battery to degrade quicker, as can frequent deep discharges. Overcharging can also cause damage to a battery, so it's essential to ensure that the charging system on your truck is working correctly.

Do you maintain your truck battery?

Yep - batteries work better when they’re maintained. Regular maintenance is crucial to extending the life of your truck battery. Keeping the battery clean and free of corrosion, checking the water levels in flooded lead-acid batteries, and making sure the charging system is functioning correctly are all essential steps in maintaining a battery's health.

By choosing a high-quality battery, keeping it maintained, and operating the truck under optimal conditions, you can maximise the lifespan of your truck's battery, ensuring that it provides you with reliable performance for years to come.
