Comparing The Built Technology

When comparing interstate vs diehard AGM batteries, keep in mind that both Diehard and Interstate are 12V AGM batteries.

AGM (Absorbent Glass Mat) is a technology that uses a glass plate module, which are improved lead-acid batteries with a voltage of 12V that provide greater power to satisfy the increasing electrical needs of today’s automobiles and start-stop applications.

Interstate batteries may be used as a cranking battery and a source of power for your engine. It has a non-alloy lead plate design that is one of the most reliable. Even for the trolling motors, ATVs, wheelchairs, scooters, an Interstate battery with a 55Amp-hour rate works fine.

Diehard batteries’ energy flow has increased by 60 percent. Its non-alloy lead plate design is one of the most reliable on the market. Their design claims a 20% reduction in greenhouse gas emissions.

Batteries from Diehard are usually constructed using cutting-edge technology and appear to be capable of supplying the power requirements of a wide range of automobiles.

Best Use

Diehard is suitable for usage in a wide range of automobiles. It has versions that satisfy deep cycling demands to models with high starting power so that it can cater to a wide range of vehicle requirements.

You can use them for heavy-duty power trucks, marine vehicles, smaller sedans, and power sports cars.

On the other hand, Interstate offers a wide choice of batteries to meet a variety of needs. They’re recognized for making high-quality batteries for golf carts, man lifts, and backup security systems.

They have a large assortment of batteries for personal and commercial vehicles, including automobiles, trucks, and other vehicles. There are also batteries for RVs, marine vehicles, utility vehicles, and motorcycles.

Longevity

Let’s start with diehard batteries. If you reside in a colder northern area, it usually lasts for around five years or more. However, if you, as a battery user, dwell in America’s hot southern environment, such a car battery would normally last only three years.

On the other hand, an interstate battery typically lasts three to five years. Even bad driving habits will reduce battery life. Furthermore, the more a battery is exposed to severe environments, the less durable it becomes. But we see people having such reliability on the Interstate batteries for their car, jeep, and van.

Performance Difference

Duralast batteries have a polypropylene structure that is impact-resistant, reducing the risk of damage caused by vibration. Furthermore, the in-class vent mechanism ensures that gases in the system are vented, reducing corrosion and leakage.

You’ll observe that Interstate batteries often have an average CCA of 800 cold-cranking amps and an average CA total of 1000 cranking amps. Still, Duralast batteries have 720 cold-cranking amps and a total range of 910 cranking amps, making them somewhat more potent in power output.

While talking about diehard vs interstate marine battery, you will notice that The 110.00 Interstate AH marine battery requires no maintenance. It has a long life and is hence suitable for deep discharge applications. So, in short, it works much better for marine vehicles compared to Duralast.
