What Is a Group 24 Battery?
A Group 24 battery refers to a standardized size classification for lead-acid or lithium-ion batteries, defined by the Battery Council International (BCI). These batteries measure approximately 10.25 x 6.8 x 8.8 inches and are commonly used in automotive, marine, and RV applications. Their capacity ranges from 70-85 Ah, balancing power output and physical dimensions for versatile use.
What Is a Group Size 24 Battery?
How Does Group 24 Compare to Other Battery Sizes?
Group 24 batteries are smaller than Group 27 (12 x 6.8 x 8.8 inches) and Group 31 (13 x 6.8 x 9.4 inches) but larger than Group 34 (10.25 x 6.8 x 7.8 inches). They provide a middle ground in capacity and size, making them ideal for mid-sized vehicles and equipment requiring moderate energy storage without excessive bulk.
What Are the Key Specifications of a Group 24 Battery?
- Voltage: 12V (standard for automotive use)
- Capacity: 70-85 Ah
- Cold Cranking Amps (CCA): 600-800A
- Terminal Type: Top-post or side-post configurations
- Weight: 40-50 lbs (flooded lead-acid) or 25-30 lbs (AGM/lithium)
Where Are Group 24 Batteries Commonly Used?
Group 24 batteries power boats, RVs, trucks, and backup solar systems. Marine versions feature thicker plates for vibration resistance, while deep-cycle variants support trolling motors or off-grid energy storage. Automotive applications prioritize high CCA for reliable engine starts in moderate climates.

In marine environments, Group 24 batteries are often paired with dual-purpose or deep-cycle designs to handle both engine starting and accessory loads. For RVs, they serve as house batteries for lighting, refrigeration, and inverters, though users with higher energy demands may need to connect multiple units in parallel. In trucks, their compact size fits snugly in engine compartments while delivering sufficient power for auxiliary devices like winches or refrigeration units. Their adaptability also extends to renewable energy systems, where they store solar or wind energy for off-grid cabins or emergency backup setups.
What Are the Pros and Cons of Group 24 Batteries?
Pros:
– Balanced size-to-power ratio
– Wide compatibility with vehicles and equipment
– Available in AGM, lithium, and flooded lead-acid chemistries
Cons:
– Limited capacity for high-demand applications
– Shorter lifespan in extreme temperatures
How to Choose Between Flooded, AGM, and Lithium Group 24 Batteries?
Flooded: Budget-friendly but requires maintenance.
AGM: Maintenance-free, spill-proof, and vibration-resistant.
Lithium: Lightweight, long-lasting (2,000+ cycles), but 3x more expensive. Choose based on budget, usage frequency, and environmental conditions.
What Maintenance Does a Group 24 Battery Require?
For flooded lead-acid:
– Check electrolyte levels monthly
– Clean terminals to prevent corrosion
– Recharge after 50% discharge
AGM and lithium batteries need minimal maintenance but benefit from periodic voltage checks and storage at 50-80% charge.
How Long Does a Group 24 Battery Last?
Lifespan varies by chemistry:
– Flooded: 3-5 years
– AGM: 4-6 years
– Lithium: 8-12 years
Proper maintenance, avoiding deep discharges, and temperature control (ideally 50-80°F) maximize longevity. For example, a lithium Group 24 battery used in a temperate climate with regular partial discharges can exceed 10 years, while a flooded battery in a hot environment might degrade in 2-3 years. Below is a comparison of average lifespans under different conditions:
| Chemistry | Moderate Climate | Hot Climate | Cold Climate |
|---|---|---|---|
| Flooded | 4 years | 2.5 years | 3 years |
| AGM | 5 years | 3.5 years | 4 years |
| Lithium | 10+ years | 8 years | 9 years |
Expert Views
“Group 24 batteries remain popular due to their adaptability. However, lithium-ion variants are gaining traction in marine and RV markets, offering weight savings and deeper cycling capabilities. Always match the battery’s CCA and Ah ratings to your system’s demands to prevent premature failure.”
