Are Duralast Batteries any Good?

Duralast is a popular and quality car battery manufactured by Autozone. This manufacturing company, Autozone, also has several other quality brands.

The answer to this question depends on the grade of the Duralast battery you want to buy. The brand has many battery grades and different prices according to its quality and performance.

If not, it might cut your expectations, and you’ll eventually leave bad feedback on this brand.

Who makes Duralast Batteries for Autozone?

Some Duralast batteries are manufactured by Johnson control, which is known for producing other popular brands like Ac Delco, Varta, Optima, Delkor, Heliar, Diehard, LTH, and many others.

However, other manufacturers make batteries for Autozone. The notable ones include East Penn and Exide.

A brief history of the manufacturers

You must have seen there are many Duralast battery manufacturers. So, speaking of the manufacturers, it may not be possible to talk about all the manufacturers.

We have decided to talk about only three companies that manufacture a significant part of Duralast total production in the United States.

East Penn

East Penn is renowned and the world’s largest single-site lead-acid battery producer. They produce a large number of batteries for Autozone. It is a privately owned company.

East Penn has gained a solid gold reputation for manufacturing only quality and long-lasting batteries.

Their production line incorporates costly gel batteries, but it’s one of the best the market has to offer.

If you’re after a long-lasting and high-quality battery, you need to invest in platinum Duralast batteries manufactured by East Penn.

They are known for producing deep-cycle batteries as well as accessories like battery chargers.

Johnson Controls

Johnson control is an American-Irish domiciled multinational conglomerate industry based in Ireland.

Among the three notable manufacturers, Johnson control manufactures a greater quantity of total Duralast production.

This battery maker has offices on 6 continents and operates in 2,000 locations across the world.

They have over 105,000 employees across the globe. As of 2018, they had a total company net of 2.4 billion us dollars. You can imagine how big they are.

However, Johnson controls have sold its automotive business battery division to Brookfield business partners. The new owners of the company are gradually trying to rebrand to Clarios.

Clarios is making more deals and implementing new strategies and technologies to hit the market so hard. You can confidently buy Duralast gold batteries manufactured by Clarios or Johnson controls.


Exide is a manufacturing and the most significant selling battery company and a life insurance company in Kolkata, India. They are known for producing batteries in various sizes and battery accessories like battery boosters and cables. They also manufacture inverter batteries.
