Your Diesel Truck Questions Answered

In general, Roseville drivers tend to ask around five common questions about diesel engines, ranging from the definition of diesel itself to information about how diesel batteries work. Check out the answers to these five FAQs below:

How does diesel differ from gasoline?

Let’s start by defining diesel and discussing how it’s different from gasoline. Diesel compresses air at a higher ratio than gasoline and doesn’t use a spark plug to ignite the fuel; the higher compression ratio allows the fuel to self-ignite. Diesel engines tend to be more fuel-efficient and longer-lasting than gasoline engines because of their robust construction. Diesel is used in trucks more often than in other vehicles because it’s ideal for long-distance highway driving.

How many batteries do diesel trucks have?

Most vehicles require a single battery to run the engine, but diesel trucks are powered by two batteries under the hood. The way diesel engines are constructed requires more power to turn the engine over than is required for a gasoline engine, and the second battery provides that extra boost of power.

Which battery starts a diesel truck?

Unlike hybrid or electric vehicles, which sometimes have one “main” battery and one smaller secondary battery, the two batteries in diesel trucks run in tandem and operate simultaneously. This means that if one starts to wear out, it’s a good idea to go ahead and get both replaced.

How much does a diesel truck battery weigh?

There’s no one answer to this question since engines, batteries, and trucks all come in different sizes. However, on average, you can expect a single diesel battery to weigh anywhere between 40 and 80 pounds. 

How many volts is a diesel truck battery?

The diesel battery setup runs on a 12-volt system. Diesel engines are either set up in a parallel or series setup, but almost all diesel trucks today run on parallel batteries. This means that the negative and positive terminals of both batteries are connected to each other in a “criss-cross” pattern, making for a stable output of energy that prevents power surges.
