Your car’s battery powers a whole lot of accessories, including all the dashboard lights. If the battery is weak and doesn’t hold charges any longer, you’d experience several difficulties and have to jumpstart your vehicle most of the time. This is why you should go for the best durable battery for your car.
Duralast vs Diehard batteries? Duralast and Diehard are among the best car battery brands patronized by car owners globally. Both Diehard and Duralast produce different types of car batteries using patent technologies.
Duralast is a brand under AutoZone, and Diehard is a brand under Advance Auto Parts, Inc.
Well, the major difference between Duralast and Diehard batteries has to be the price because both brands offer their customers good batteries with different specifications that match the requirements of different vehicles.
What You Need To Know About Duralast Batteries
Duralast is a brand under AutoZone that produces some of the best car batteries on the market. You’d find a suitable Duralast battery for your car or truck vehicle. The brand manufacture both AGM batteries and flooded lead batteries.
Each Duralast battery model came with unique specifications for use on specific vehicles. Also, Duralast batteries are remarkable for their outstanding Cold Cranking Amps (CCA), which makes starting your car in freezing temps seamless.
What You Need To Know About Diehard Batteries
Advance Auto Parts, Inc. acquired the Diehard Battery brand in 2019. The brand produces some of the best quality and most reliable car batteries. Diehard batteries are priced competitively, and there are many types available for different vehicles.
Diehard also produces car batteries with different Cold Cranking Amps (CCA) ratings up to 810, which make the batteries usable even in cities where the climate is usually low. Just like Duralast, Diehard makes both AGM and Flooded Lead batteries.
Duralast Vs Diehard: The Comparison
| Brand/Factor | Duralast | Diehard |
| Types | AGM and Flooded Lead | AGM and Flooded Lead |
| CCA | Up to 710amps | Up to 810amps |
| Cranking Amps (CA) | Up to 885amps | Up to 1000amps |
| Reserve Capacity (RC) | Up to 120mins | Up to 120mins |
| Voltage | 12V | 12V |
| Variations | Regular, Gold, and Platinum | Red, Silver, Gold, Platinum, and Platinum AGM |
| Price | Competitive | Competitive |
Battery Types
Diehard and Duralast make the same types of car batteries, which are basically two types, Absorbent Glass Mat batteries (AGM) and Flooded Lead batteries. AGM batteries are common in modern cars, while flooded lead-acid batteries are found in older cars.
Flooded lead-acid batteries are built with a liquid electrolyte, which activates to trigger the battery’s chemical components to power your car’s engine. The acids are bonded with lead plates.
On the other hand, AGM batteries are built with chemicals too, but these chemicals (sulfuric acid and lead) are bonded in fiberglass mats to reduce the battery weight and improve performance. Diehard and Duralast produce both of these battery types.
Cold Cranking Amps (CCA)
Cold cranking amps are the ability of a battery to start an engine in cold temperatures. CCA refers to the amount of current a fully charged 12V battery can supply in 30 seconds while maintaining 7.2V at 0°F (-18°C).
The higher the CCA of a battery, the more better it’d perform in colder or freezing temperatures. Diehard manufactures different battery models that produce up to 800 CCA, while Duralast batteries produce up to 710 CCA.
Cranking Amps (CA)
CA and CCA are different. CA – Cranking Amps refers to the amount of current a battery can hold for 30 seconds under normal temperatures of 32°F. The CA of a battery tells the amount of charge the battery would deliver when starting up your car at normal temperature.
Again, both Duralast and Diehard makes car batteries with different Cranking Amps rating. Depending on the battery model you bought, the CA rating for Duralast batteries stands between 710 and 885, while Diehard batteries CA stand between 800 and 1000.
Reserve Capacity (RC)
Just like CCA and CA, the higher a battery’s reserve capacity, the more preferable the battery would be to most car owners.
Reserve Capacity refers to the duration (in minutes) in which a fully-charged 12V battery can supply/retain 25amps current before discharging to 10.5V or lower. Duralast batteries have an RC rating of up to 120 minutes, while Diehard batteries have a maximum of 115 minutes.
Conclusion
This Duralast vs. Diehard batteries comparison centers on the main differences between the two top car battery manufacturers.
Duralast and Diehard manufacture series of 12V batteries with different CA, CCA, and RC ratings, suitable for different car models. You should buy the battery that suits your car perfectly.
The prices of Duralast and Diehard batteries vary from series to series, but Duralast batteries appear to be cheaper.
Choosing between these two brands depends on your budget and battery requirement; you should pick the brand that offers sufficient CCA, CA, and RC to crank your car when you travel across cities of different climates.
