Group 24 batteries are mid-sized lead-acid batteries used in cars, trucks, marine vehicles, and RVs requiring 600-800 CCA. Compatible models include Honda CR-V (2012-2016), Subaru Outback (2010-2014), select Ford F-150 trims, and marine applications like bass boats. Always verify dimensions (10.3″ L x 6.8″ W x 8.9″ H) before replacement.
What Is a Group Size 24 Battery?
How Does Group 24 Compare to Other Battery Sizes?
Group 24 batteries fill the gap between compact Group 35 (9.1″ L) and larger Group 27 (12″ L) sizes. They provide 15-20% more reserve capacity than Group 35 but maintain a smaller footprint than marine-focused Group 31. Key differentiation includes dual-terminal configurations (top/side posts) not found in smaller automotive batteries.
Which Automotive Brands Commonly Use Group 24 Batteries?
Asian automakers dominate Group 24 applications:
• Honda: CR-V, Pilot (2010-2015)
• Toyota: 4Runner (2003-2009), Tacoma (2005-2012)
• Subaru: Legacy, Forester (base trims)
• Nissan: Frontier (2004-2014)
Domestic use appears in Chrysler Pacifica hybrids and Jeep Wranglers with aftermarket audio upgrades.

Japanese manufacturers particularly favor Group 24 batteries for their balance between power output and space efficiency in mid-size SUVs. The Honda Pilot’s 3.5L V6 engine specifically requires the Group 24’s 700 CCA rating for reliable cold starts. In Toyota trucks, the battery compartment design accommodates Group 24’s specific height clearance (8.9″) without requiring tray modifications. Recent trends show Korean automakers like Kia adopting this size for their Telluride models’ auxiliary systems, though not as primary starting batteries. For marine conversions, Group 24 remains popular in pontoon boats and cabin cruisers due to its dual-purpose capabilities.
| Vehicle Type | Common Group 24 Applications | Typical CCA Requirement |
|---|---|---|
| Mid-size SUV | Honda CR-V, Toyota 4Runner | 650-750 |
| Light Truck | Nissan Frontier, Ford Ranger | 700-800 |
| Marine | Bayliner Capri, Tracker Pro Guide | 550-700 (Marine Cranking Amps) |
What Are the Weight Specifications of Group 24 Batteries?
Standard flooded lead-acid Group 24 batteries weigh 39-43 lbs, while AGM variants reach 47-52 lbs. The weight distribution correlates with plate thickness – marine deep-cycle versions have 11% heavier plates than automotive starting batteries. Weight impacts vibration resistance, with heavier AGM models preferred for off-road vehicles.
When Should You Replace a Group 24 Battery?
Replace when:
1. CCA drops below 75% of rated capacity (tested at 0°F)
2. Voltage recovery exceeds 2 hours after charging
3. Visible case deformation or terminal corrosion
4. Frequent jump-starts in moderate temperatures
Average lifespan: 3-5 years in automotive use, 2-4 years in marine applications.
Why Choose AGM Over Flooded Group 24 Batteries?
AGM (Absorbent Glass Mat) batteries offer:
• 3x vibration resistance (MIL-STD-810G compliant)
• Spill-proof operation at 45° inclines
• Faster recharge acceptance (40% reduction in charging time)
• 2x cycle life in deep-discharge applications
Ideal for marine use, luxury vehicles with start-stop systems, and aftermarket electronics.
The sealed construction of AGM batteries makes them particularly advantageous for vehicles experiencing extreme temperature fluctuations. Unlike flooded batteries, AGM versions maintain consistent performance from -30°F to 140°F due to recombinant gas technology. They’re mandatory for Mercedes-Benz and BMW models with intelligent charging systems that require precise voltage regulation. Off-road enthusiasts appreciate AGM’s resistance to electrolyte stratification during prolonged angles – a common issue in flooded batteries when navigating steep trails. While costing 30-50% more upfront, AGM’s maintenance-free operation and longer service life often justify the investment for high-demand applications.
“The Group 24 market is shifting towards lithium-ion conversions. While only 12% of applications currently use LiFePO4 chemistry, we’re seeing 300% year-over-year growth in drop-in replacements for RV and marine markets. These provide 60% weight reduction and 2000+ deep cycles but require compatible charging systems.”
