Understanding Group Size 24 Battery Specifications

When selecting a Group 24 battery, it is important to note the terminal orientation and physical size to ensure it fits your battery tray and cable reach. Unlike the "Group 24F" variant, the standard Group 24 has the positive terminal located on the left side when looking at the front of the battery.

Group 24 Battery Dimensions

Standard Group 24 dimensions are approximately:

  • Length: 10.25 inches (260 mm)
  • Width: 6.81 inches (173 mm)
  • Height: 8.88 inches (225 mm)

Specialized Technologies for Every Application

Our Group 24 inventory features three distinct high-end chemistries to match your specific performance requirements:

  • Odyssey ODX-AGM24 (Extreme Series): Utilizing Thin Plate Pure Lead (TPPL) technology, this battery provides enormous cranking power and exceptional deep-cycle capability. It is the ultimate choice for vehicles with heavy winches, high-end audio systems, or those operating in brutal temperature extremes.
  • Deka Intimidator 8A24 AGM: A premium, American-made AGM battery that offers a spill-proof, maintenance-free design. It is highly resistant to vibration and provides consistent starting power for daily drivers and light-duty commercial use.
  • Deka Dominator 8G24 Gel: Unlike standard AGM batteries, the Deka Dominator uses a specialized gelled electrolyte. This makes it one of the best choices for deep-cycle applications where the battery will be discharged frequently, such as in marine house banks or solar power storage.
  • Antigravity AG-24-40-RS Lithium: The modern solution for weight-conscious drivers. This LiFePO4 battery is up to 70% lighter than lead-acid alternatives and features a built-in "RE-START" button that saves enough energy to start your car if you accidentally leave the lights on.

Maintenance-Free Reliability

All of the Group 24 batteries we carry—whether Gel, AGM, or Lithium—are completely sealed and maintenance-free. This eliminates the need to check water levels and prevents terminal corrosion, ensuring a cleaner engine bay and a longer-lasting investment.

Choosing the Right Fit

Selecting the right Group 24 battery depends on your primary use case. If you need maximum starting power and durability, Odyssey is the industry leader. For deep-discharge applications where longevity is the priority, Deka Gel is unmatched. If you want the most advanced technology with built-in jump-starting safety, Antigravity Lithium is the ideal upgrade.
