What is Group 24 Battery?

A Group 24 battery is a specific size and type of battery commonly used in vehicles, backup power systems, and medical equipment. It is classified based on its physical dimensions and terminal layout, which are standardized by the Battery Council International (BCI). Understanding the characteristics of a Group 24 battery can help you determine if it's the right fit for your application.

Group 24 Battery Dimensions

The Group 24 battery size is defined by the following dimensions:

  • Length: 10.25 inches (266.7 mm)
  • Width: 6.75 inches (174.6 mm)
  • Height: 9 inches (225.4 mm)

However, there are slight variations within the Group 24 category, known as subcategories like Group 24F, 24H, 24R, and 24T, each with slightly different dimensions to accommodate specific applications.

Group 24 Battery Specifications

In addition to the physical dimensions, Group 24 batteries have the following typical specifications:

  • Voltage:12 Volts
  • Cold Cranking Amps (CCA): 700 CCA
  • Cranking Amps (CA): 875 CA
  • Reserve Capacity (RC): 120-130 minutes

These specifications indicate the battery's ability to start an engine in cold temperatures (CCA), its overall starting power (CA), and the duration it can sustain a load before needing a recharge (RC).

Deep Cycle vs. Starting Battery

Group 24 batteries are primarily designed as deep cycle batteries, meaning they are optimized for providing a steady flow of power over an extended period. This makes them suitable for applications like RVs, boats, and backup power systems that require sustained energy delivery. However, they can also be used as starting batteries in some vehicles, although they may not perform as well as dedicated starting batteries in extremely cold conditions.

Applications and Advantages

Group 24 batteries find applications in a wide range of industries and settings, including:

Automotive: These batteries are used in cars, trucks, and other vehicles as starting or deep cycle batteries.

Marine: Boats and other watercraft often rely on Group 24 batteries for power, thanks to their deep cycle capabilities.

Recreational Vehicles (RVs): RVs require reliable power sources for their electrical systems, making Group 24 batteries a popular choice.

Backup Power Systems: In case of power outages, Group 24 batteries can provide backup power for essential equipment and systems.

Medical Equipment: Many medical devices and equipment rely on Group 24 batteries for their power needs.

Other advantages of using Group 24 batteries include their versatility, cost-effectiveness, and compact size. Their size allows them to fit in various battery compartments and spaces, while their capacity and performance make them suitable for a wide range of applications.

Lithium-Ion Group 24 Batteries

While traditional Group 24 batteries are lead-acid based, lithium-ion versions are also available. Lithium-ion Group 24 batteries offer advantages like higher energy density, longer lifespan, and better performance in extreme temperatures. However, they typically come at a higher upfront cost.

When selecting a Group 24 battery, it's essential to consider factors like your application's power requirements, available space, and environmental conditions. Consulting with battery experts or referring to your vehicle's owner's manual can help ensure you choose the right battery for your needs.
