Key Features and Specifications
Both Duralast and Diehard batteries share some fundamental features, but there are subtle differences worth noting.
Battery Chemistry
Both brands offer batteries with lead-acid chemistry, the most common type found in vehicles. Lead-acid batteries consist of lead plates immersed in an electrolyte solution.
* **Flooded Lead-Acid:** These are the traditional type of car batteries, requiring regular maintenance, including checking and topping up the electrolyte levels.
* **AGM (Absorbent Glass Mat):** AGM batteries use a fiberglass mat to absorb the electrolyte, eliminating the need for regular maintenance and making them more resistant to spills and vibrations.
Cold Cranking Amps (CCA)
CCA measures a battery’s ability to start an engine in cold temperatures. Higher CCA ratings indicate better starting power in frigid conditions. Both Duralast and Diehard offer batteries with varying CCA ratings to suit different climates and engine sizes. (See Also: Which Terminal Do You Remove First On A Car Battery? – The Right Way)
