How to Jumpstart a Diesel Truck with 2 Batteries

When you are operating a car with heavy-weight-driven engine you know that in case there is a case of dead battery then it will be more complicated as compared to the normal car. Diesel engines are very stiff to boot up and therefore most of the rigs use dual battery system. This skill is to be able to jump-start a two-battery diesel truck, and this is a skill that all vehicle drivers (fleet operators or assumed individual pickup owners) should have.

Our company is a high technology company, JOZOKING (TIANJIN) TECHNOLOGY Co., LTD. and it deals with high quality solutions of energy. Our products are relied on harsh markets within Europe, North and Australia to semi truck batteries to advanced lithium and LiFePO 4 batteries. For the right jumpstarting procedure and what you can do to maintain your rig running we are going through it.

Understanding Dual Semi Battery Systems

You had better know what you are handling before you go on to make a leap. Heavy duty automobiles like a tractor trailer battery have a standard 2 12 voltage battery wired in series. This arrangement keeps the voltage at 12V, but doubles the amperage (cranking power) to power a huge diesel engine.

A case where a battery needs replacement in a truck is delicate and the two batteries should be replaced at the same time. An old battery should not be interchanged with a new battery because the former will over strain the new battery and malfunction prematurely.

Step-by-Step: How to Jumpstart a Diesel Truck with 2 Batteries

Jump starting a diesel truck using 2 batteries takes more power and is a different process compared to jump starting a regular sedan. These are the steps to be followed:

Prepare the Vehicles: Hold the working donor vehicle (preferably another truck) near enough so that the jumper cables can reach, but not contact the vehicles.

Locate the Batteries: Find the two batteries. Some semi truck batteries are arranged so that they are in a side box, or under a step.

Connect to the Dead Truck (Correct Order):

Have one red clamp attached to the positive side of the first battery.

Connect the other red clamp on the positive (+) terminal of the second battery.

Put one black clamp on the negative (-) of the first battery.

Crucial Step: Attach the last black clamp to some clean and unpainted metal surface on the engine block or frame of the dead truck-not to the negative post of the second battery. This eliminates sparks around the batteries.

Start the Donor Vehicle: Start the donor vehicle and allow it to run a few minutes in order to charge a little.

Switch on the Diesel: Attempt to start the non-functional truck. If it does not turn over at once, allow a few more minutes to accumulate a charge.

Disconnect: It is important that when the truck is running remove the cables in the same order as at their connection.

The Role of Battery Quality in Jumpstarting

The health and type of your batteries are crucial to a smooth jumpstart. We have various solutions that will help get reliable starting power in the future at JOZOKING:

AGM and Gel Technology: Gel battery to be used in cars or trucks. The gel battery provides better vibration and recovery of discharge than the old flooded batteries do. This is essential in a tractor trailer battery that is subjected to constant vibration on the road.

High Cranking Amps: Our heavy-duty automotive batteries are designed to provide the heavy start burst of power required in a cold start situation so that they do not leave you stranded in the first place.

Modern Alternatives: Although the majority of the trucks are designed with 12V, the industry is changing. The use of a 48 volt battery system is increasingly popular in auxiliary power units (APUs) in sleeper cabs to enable drivers to operate amenities without turning on the main engine.

When to Consider Truck Battery Replacement

When you are constantly having to jump start your truck then it is an obvious indication that the batteries are failing. Other indicators include:

Slow cranking (the engine is starting slowly).

Battery cases are corroded or swollen.

The batteries are more than 3-5 years.

Comparing the prices of truck batteries, it should be kept in mind that the most affordable one will not necessarily be the most cost-efficient. High quality semi battery or a heavy equipment 4d battery (size used by heavy equipment) will have a longer lifespan and more reliable and will in the end save you money on downtime and replacement cost of a battery in the truck.

At JOZOKING, we can make any kind of battery to exactly the specifications you require. You may require batteries in starting semi-trucks that have a lot of power, or you may require advanced solar energy storage systems parts and components, but you can be sure that JOZOKING will be able to provide you with power that you can rely on.
