Why Should You Buy It?

If you want to get a portable yet functional battery booster, we should go for the NOCO Boost XL GB50. This portable unit produces 1500A of peak current to let you jump-start your diesel trucks successfully.

What to Consider Before Buying Best Battery Charger for Diesel Truck?

Before choosing a battery charger for diesel trucks, take a look at the following criteria.

Peak Power

It’s important to consider the peak power if you want to get a battery booster. The higher the peak power, the more successfully you can start a diesel engine with dead batteries. Regarding this, you can go for the GOOLOO Jump Starter. It delivers up to 4000A of peak current to start any vehicle like a champ.

Voltage

Make sure you choose the right battery charger that is compatible with your truck battery. If you attach a 12V battery charger to a 6V battery, it will have a negative effect on your battery. On the other hand, if you connect your battery with a low voltage charger, it can’t charge up the battery efficiently. So, choose the trickle charge that will be compatible with your vehicle battery.

Port

You should also consider whether the battery booster or charger comes with extra ports or not. A trickle charger with USB ports will help you charge smartphones, tablets, and other USB devices. Fortunately, every battery booster or trickle charge we enlisted comes with USB ports. So, you don’t need to worry about it.

Durability

Ensure the battery booster or trickle charger is rated at IP65. Such a battery booster can resist rain, dirt, and dust. Also, make sure it comes with a rubberized over-molded casing so that it doesn’t get damaged if you drop it accidentally.

LED Flashlight

A trickle charger with an LED flashlight will change the world when it comes to hooking it up at night. Because of the LED flashlight, you can attach the clamps to your vehicle’s battery terminals in the dark. Therefore, it also helps you illuminate your camps.

Safety Features

Safety comes first, right? What if you attach the clamps wrongly to the battery terminals? Fortunately, every battery booster or trickle charge we enlisted comes with reverse polarity technology. So, you don’t need to worry about attaching the clamps incorrectly. Therefore, each battery boosters feature overload, overcurrent, and overvoltage protection systems to let you use the charger safely.

How Do You Charge A Diesel Truck Battery Or Jump-Start It?

If your diesel truck batteries are dead, you can bring back life to it by charging it with a battery charger. Alternatively, you can jump-start the dead battery with a jump starter. In this chapter, we will break down both of them.

Charging A Diesel Truck Battery:

  • Detach the negative terminal first on your battery. Then, disconnect the positive terminal. Repeat this same process for the second battery.
  • Now, connect the positive clamp with the positive terminal of your truck battery. And then, attach the negative clamp of your charger to the negative terminal of the battery. Do the same thing with the second battery and the second charger.
  • Afterward, set your charger to charge the battery on low amperage. It will take a lot of time to charge but ensure complete charge.
  • Finally, you can turn off the battery charger when it charges the battery fully. Most battery chargers come with indicators that will tell you when you need to turn off the charger.

Jump Starting A Diesel Truck:

  • Just attach the positive clamp to the positive terminal and the negative clamp to the negative terminal of your battery.
  • Turn on the jump starter.
  • Start the engine of your diesel truck. Once you start your vehicle, detach the jump starter and drive your truck.

Frequently Asked Questions

Can diesel truck run without battery?

It’s not possible to run a diesel truck or a diesel engine without a battery. Yeah, you can operate a diesel engine without an alternator. The fuel stop solenoid on the injection pump requires a continuous supply of 12 volts electricity. And without a battery, you will fail to provide 12V to the fuel stop solenoid. In short, running a diesel truck without a battery is just an imagination.

Why are there 2 batteries in diesel truck?

There are 2 batteries in a diesel truck so that it can crank at higher amps. Diesel truck requires two batteries as it demands a high-resistance load to start the engine successfully. In other words, a diesel truck needs more power than the gas truck. That’s why it has two batteries to supply the energy it needs to start the diesel engine.

Will a diesel truck start with one battery?

It actually depends on the voltage requirement of the starter motor. If the starter motor operates on 12V, a battery should be fair enough to start the diesel truck. On the other hand, you should need two batteries if the starter motor runs on 24V. So, check out the voltage requirements of the starter motor and then get one or two batteries.

How many amps do you need to start a diesel truck?

Generally, it requires at least 400 amps if you have a diesel truck. On the other hand, a larger truck requires 1000 amps to start it. When you go to buy a jump starter, take the jump starter size into account. Based on the engine size and the number of cylinders your truck has, you should pick the jump starter to get the amps you need to start a diesel truck.

How long should a diesel truck battery last?

Generally, a diesel truck battery will last around 4 years. However, the lifespan of the battery will also depend on the climate or temperature of the area you live in. In hotter climates, the batteries don’t last long. We recommend you get a diesel truck battery that comes with a better warranty. The better the warranty will be, the longer the battery will last.

Final Thoughts
