Diehard Battery Types in the US Market

Several Diehard batteries are available in the US market, including Diehard Platinum, Diehard Silver, and Diehard Gold. Each of these batteries has unique features and specifications that cater to different needs and budgets.

Diehard Platinum

The DieHard Platinum battery is known for its high performance, durability and reliability. It is made with several advanced technologies and features to increase its performance and longevity.

  • Type: The sealed lead-acid Diehard Platinum Battery uses AGM technology. The electrolytes in AGM batteries are captured by a glass mat, which ensures that the battery will not leak or spill.
  • CAA: Power output by a vehicle measured in cold-cranking amps (CCA) at -18 degrees Celsius. And the cranking amps (CA) scale is based on measurements taken at 0 Celsius. If your battery has a higher cold cranking amps (CCA) rating, you’ll quickly get the engine started when it’s chilly outside. Platinum has 850 in CAA and 1000 CA.
  • Capacity: There are 100 minutes of reserve power in every Diehard Platinum Car Battery.
  • Voltage: Platinum’s nominal voltage is 12 volts, making it compatible with any vehicle’s electrical setup using 12v.
  • Group Size: A battery’s group size indicates how much space it takes up physically. The Platinum series perfectly fits any vehicle with group 35 batteries.
  • Dimensions: The Diehard Platinum measures 10.937 x 6.937 x 7.25 inches. If your vehicle’s battery area is already cramped, this gives the Diehard Platinum Car Battery an attractive option.
  • Warranty: The company backs the quality of Diehard Platinum for 48 months with a no-questions-asked replacement guarantee.

Diehard Silver

Vehicles with a heavy electrical load might benefit from the superior performance of a Diehard Silver car battery.

  • Type: Silver is an economical lead acid battery.
  • CAA: There are 575 CAA and 720 CA available in Diehard Silver. Gold or Platinum batteries are more suitable if you live in a colder region.
  • Capacity: After the engine has shut down, it will keep providing power for up to 90 minutes thanks to the reserve capacity.
  • Voltage: The voltage of a Diehard Silver Car Battery is 12 volts.
  • Group Size: When compared to the 34 of Gold and Platinum, Silver has a larger group size at 35.
  • Dimensions: The Diehard Silver Car Battery measures 12.06 x 7.56 x 7.56 inches, which is significantly larger than the other two batteries.
  • Warranty: The warranty period for Diehard Silver is 24 months.

Diehard Gold

The voltage and group size of Diehard Gold batteries are very close to those of the Platinum series. However, a few key differences might make Gold a better option.

  • Type: Diehard Gold Lead Acid Batteries are the most common and less expensive than Platinum. Even though they don’t have quite the same leak-proof reputation as AGM batteries, they last far longer than standard batteries.
  • CAA: There are 640 CAA and 800 CA available in Diehard Gold.
  • Capacity: Diehard Gold, like Platinum, has a 100-minute reserve capacity, meaning it can maintain a 25-amp current long before it is depleted.
  • Voltage: Gold’s nominal voltage of 12 volts makes it compatible with the electrical systems of all vehicles that use that voltage.
  • Group Size: Gold is the same group 35 battery size as Platinum.
  • Dimensions: The Diehard Gold is larger than the Platinum, measuring 9.06 x 6.937 x 8.875.
  • Warranty: The warranty period for Diehard Gold is 36 months.

The lifespan of a DieHard battery can vary depending on several factors, such as the type of battery, the vehicle it is used in, and the driving conditions. However, on average, a DieHard battery can last between 3 and 5 years.

DieHard Platinum batteries, an advanced AGM (Absorbed Glass Mat) battery, are known for lasting longer than traditional lead-acid batteries, up to 5 years. DieHard Silver and Gold batteries, which are conventional lead-acid batteries, have a lifespan of around 3-5 years.

Does Diehard Honor Their Battery Warranty?

DieHard honors their battery warranty, but only under certain conditions. A free replacement warranty that lasts between two and four years is included with every DieHard battery. The length of the guarantee changes with the battery model you choose.
