What is the history of Duralast batteries?

The automotive battery brand Duralast is available in the US, Mexico, and Canada. Johnson Controls, Inc., a leader in energy storage technologies, makes the batteries. The first Duralast batteries were introduced in 1995 by AutoZone, a well-known retailer, and distributor of automotive parts and accessories, under the Duralast brand. The batteries were designed to meet the demands of customers who desired a dependable, cost-effective battery with long life.

Johnson Controls’ expertise in battery manufacturing and technology was utilized by AutoZone in its partnership with the company to produce the Duralast batteries. Due to its premium design, top-notch functionality, and affordable pricing, the Duralast brand quickly gained popularity among consumers.

The Duralast line of automotive batteries has grown over time to include a variety of automotive batteries, from conventional lead-acid batteries to AGM and EFB batteries created for contemporary vehicles with intricate electrical systems. To fit almost any make and model of car, Duralast batteries come in a wide range of sizes and power ratings. With a reputation for quality, performance, and value, Duralast batteries are one of the most respected brands in the car battery market today.

How does a Duralast battery work?

Using a process known as an electrochemical reaction, Duralast batteries work by converting chemical energy into electrical energy. A sequence of positive and negative terminals, lead plates, an electrolyte, and a plastic or hard rubber case make up the battery. An electrical current flow between the positive and negative terminals of the battery when it is connected to a circuit due to a chemical interaction between the electrolyte and lead plates. Direct current (DC) electrical current, which is created by this flow of electrons, can be used to power a vehicle’s electrical systems and parts.

The lead and lead oxide mixture that makes up the battery’s lead plates react with the electrolyte of sulfuric acid to generate power. Sulfuric acid and distilled water are combined to create the electrolyte, which enhances the chemical reaction between the lead plates and generates the required ions for the electrochemical reaction. In order to deliver better performance and endurance, Duralast batteries also make use of cutting-edge technologies like Absorbed Glass Mat (AGM) and Enhanced Flooded Batteries (EFB).

For instance, AGM batteries employ a specific glass mat that absorbs and immobilizes the electrolyte to stop leakage and spillage. The carbon addition used in EFB batteries, in contrast, enhances the battery’s capacity to endure high electrical demands and challenging driving circumstances. In general, Duralast batteries function by generating electricity through a chemical reaction between the lead plates and electrolytes, which can power the electrical systems and parts of a vehicle.

What are the differences between Duralast gold & platinum?

differences between Duralast gold & platinum

Here are the differences between Duralast gold & platinum:


Finding the appropriate automobile battery with Duralast should be simple when it comes to fitting your car. The company makes sure that every vehicle has a compatible battery. The spill-proof construction of the Duralast Platinum is its best feature. A Platinum battery can be mounted in any position in your truck, car, or SUV, unlike the gold series.

Cold-Cranking Amperage (CCA)

You can determine how effectively a battery will start in cold weather by looking at its cold-cranking amperage rating. High CCA ratings indicate that the battery has more starting power under all circumstances. The CCA rating is one of the key differences between the Gold and Platinum linkups. In comparison to gold versions, Platinum models have better CCA ratings.


Either line-up will have a long lifespan, so choose wisely. The warranties for the Gold and Platinum batteries are three years. Yet, the Platinum battery’s construction may enable it to last beyond what was expected. The higher-end model might last longer even though the warranty is the same.

Reverse Capacity

How long the battery can run on a single charge is determined by its reserve capacity. Knowing this grade is crucial, especially if you want to drive in severe weather. The Gold line-up of Duralast is only certified for 150 minutes whereas the Platinum line-up offers a reserve capacity of 200 minutes.


It’s crucial to assess the batteries’ voltage as well. The majority of car batteries have a 12-volt rating. You may anticipate the same voltage whether you select the Gold or Platinum battery. These two batteries have a 12-volt capacity.


When buying a new car battery, you cannot undervalue the importance of setting a budget. While it’s crucial to keep costs as low as possible, you need also to consider the value. The Duralast Platinum will be more expensive than the gold version.
