A Group 24 battery fits vehicles requiring mid-sized power sources, including boats, RVs, trucks, and select SUVs. Designed with dimensions of 10.25″ x 6.8″ x 8.9″, it delivers 70-85 Ah capacity and 600-800 CCA, balancing compactness with high output. Compatibility depends on terminal placement, voltage, and physical space—critical for marine and automotive applications.
What Is a Group Size 24 Battery?
How to Determine If a Group 24 Battery Fits Your Vehicle?
Measure your vehicle’s battery compartment and compare it to Group 24 dimensions. Check terminal positions (top-post or side-post) and ensure voltage matches your system (12V for most applications). Consult your owner’s manual or use online fitment tools from brands like Optima or Interstate Batteries.
What Are the Key Specifications of Group 24 Batteries?
Group 24 batteries typically offer 70-85 amp-hours (Ah), 600-800 cold cranking amps (CCA), and 120-180 minute reserve capacity. Weight ranges 40-50 lbs. Flooded, AGM, and gel-cell variants exist, with AGM excelling in vibration resistance—critical for marine use.

Which Vehicles Are Most Compatible with Group 24 Batteries?
Common fits include Ford F-150 (2010-2014), Chevy Silverado 1500, Jeep Wrangler JK, Honda CR-V, and marine vessels like Bayliner Capri. RV chassis such as Thor Axis and Winnebago View also use Group 24 for auxiliary power.
Beyond these models, Group 24 batteries are increasingly adopted in hybrid marine applications. Pontoon boats with trolling motors often utilize dual Group 24 setups – one for starting and another dedicated to accessories. In commercial vehicles, delivery vans like Mercedes Sprinter (2015-2020) frequently employ this size for balance between cargo space and electrical demands. Below is a compatibility table showing amp-hour requirements for common vehicles:
| Vehicle Model | Minimum Ah | Preferred Type |
|---|---|---|
| Ford F-150 (5.0L V8) | 75 | AGM |
| Bayliner VR5 Bowrider | 80 | Marine Deep Cycle |
| Winnebago View | 85 | Dual AGM |
Why Choose Group 24 Over Other Battery Sizes?
Group 24 balances power density and space efficiency better than smaller Group 35 (limited CCA) or larger Group 27 (excessive size for compact engine bays). Its 20-25% higher reserve capacity vs. Group 34 makes it ideal for dual-battery RV/marine setups.
How Does Climate Affect Group 24 Battery Performance?
Extreme cold reduces CCA efficiency—opt for 800+ CCA models in sub-zero climates. Heat accelerates sulfation; AGM batteries lose 3-5% less capacity annually in hot environments compared to flooded variants.
In tropical climates with consistent 90°F+ temperatures, battery case design becomes crucial. Group 24 AGM batteries with pressure-relief valves outperform standard models by 18% in humidity resistance tests. For arctic conditions (-22°F), look for Nordic-certified versions containing thickened electrolytes. Below are performance comparisons across temperature ranges:
| Temperature Range | CCA Retention | Recommended Maintenance |
|---|---|---|
| -22°F to 32°F | 68% | Monthly voltage checks |
| 32°F to 100°F | 89% | Bi-annual load testing |
| 100°F+ | 74% | Quarterly terminal cleaning |
Can Group 24 Batteries Power Aftermarket Electronics?
Yes. With 85Ah capacity, a Group 24 can support 1000W audio systems (drawing ~83A) for 1 hour at full load. For winches or inverters, pair with a deep-cycle variant offering 100+ cycle life at 50% depth of discharge.
What Maintenance Extends a Group 24 Battery’s Lifespan?
Keep terminals corrosion-free using lithium grease. For flooded batteries, maintain electrolyte levels with distilled water. Monthly voltage checks (12.4V+ at rest) and annual load testing prevent premature failure. In RVs, use a battery tender during storage.
Expert Views
“Group 24 remains the Swiss Army knife of mid-sized batteries. While lithium options gain traction, AGM Group 24s still dominate marine markets due to vibration tolerance—we’ve seen 30% fewer warranty claims versus standard flooded batteries.”
— Michael Torres, Lead Engineer, Coastal Marine Power Systems
Conclusion
Group 24 batteries offer versatile compatibility across automotive, marine, and RV applications. By matching specifications to your vehicle’s demands and environmental conditions, you can optimize performance and longevity. Regular maintenance and proper selection between flooded/AGM types ensure reliable power for 3-5 years.
FAQ
- Can I replace a Group 35 with a Group 24 battery?
- Only if compartment space allows—Group 24 is 0.7″ longer than Group 35. Verify terminal alignment and ensure hold-down brackets can adjust to the larger size.
- Do Group 24 batteries work for solar storage?
- While possible, lithium batteries offer better depth-of-discharge (80% vs 50% for lead-acid). For small solar setups, use two Group 24 deep-cycle AGMs in parallel.
- How long to charge a dead Group 24 battery?
- With a 10-amp charger: 8-12 hours for full recharge from 50% discharge. Avoid fast-charging above 15A to prevent plate warping in flooded types.
