What vehicles use a Group 24 battery? Group 24 batteries fit mid-sized cars, boats, RVs, and light trucks. They provide 70-85 Ah capacity and 600-800 CCA, balancing power and size for engines requiring moderate cranking amps. Compatible brands include Honda, Toyota, and marine applications like sailboats. Always check your vehicle manual for exact specifications.
What Is a Group Size 24 Battery?
How Does a Group 24 Battery Compare to Other Sizes?
Group 24 batteries are smaller than Group 27/31 but larger than Group 35. They offer 12-15% less capacity than Group 31 but fit tighter engine compartments. Their dimensions (10.25″ x 6.75″ x 8.75″) make them ideal for vehicles where space efficiency matters without sacrificing cold-cranking performance.
| Battery Group | Length (inches) | CCA Range | Common Applications |
|---|---|---|---|
| 24 | 10.25 | 600-800 | Mid-size SUVs, fishing boats |
| 27 | 12.06 | 750-900 | Full-size trucks, RVs |
| 35 | 9.06 | 500-650 | Compact cars, hybrids |
This size comparison reveals why Group 24 remains popular for marine applications – its compact footprint allows installation in cramped bilge areas while still delivering sufficient power for fishfinders and trolling motors. Automotive technicians often recommend Group 24 for vehicles with aftermarket audio systems due to its balance between reserve capacity and physical dimensions.

Why Choose AGM Over Flooded Group 24 Batteries?
AGM Group 24 batteries offer 2x vibration resistance, spill-proof operation, and 3-5x faster recharge than flooded equivalents. While costing 30-40% more, they last 6-8 years vs 3-4 years for flooded types. Ideal for marine/RV use where tilt resistance matters.
“Modern AGM batteries maintain stable voltage output even at 45-degree angles, making them indispensable for sailboats and off-road vehicles. Their sealed construction prevents acid stratification issues common in flooded batteries during long storage periods.”
The maintenance-free nature of AGM technology proves particularly valuable for seasonal users. Unlike flooded batteries that require monthly water top-ups, AGM variants can sit idle for 6-8 months without losing charge. Their lower internal resistance also supports higher accessory loads, making them suitable for RVs with multiple appliances.
Which Battery Terminals Does Group 24 Use?
Most Group 24 batteries feature SAE standard top-post terminals (0.75″ diameter), though some marine variants include dual terminals (top-post + side terminals). Terminal placement varies by brand – consult your vehicle’s wiring diagram to ensure proper polarity alignment before installation.
When Should You Upgrade to Group 24 Lithium?
Upgrade to lithium Group 24 batteries if you need 50% weight reduction (from 45 lbs to 22 lbs), 2000+ cycles vs 500 in lead-acid, and 95% depth of discharge. Best for off-grid solar systems or performance vehicles where weight distribution impacts handling.
Expert Views
“The Group 24 market is shifting toward dual-purpose designs – 65% of our marine customers now want batteries that handle engine starting and deep-cycle needs simultaneously. Lithium-ion adoption grew 300% year-over-year, though lead-acid still dominates 80% of replacement markets due to upfront cost sensitivity.”

Conclusion
Group 24 batteries serve as versatile power solutions across automotive and marine sectors. While traditional flooded batteries remain popular, emerging technologies like AGM and lithium are redefining performance expectations. Always verify physical dimensions, terminal type, and CCA requirements against your vehicle’s specifications when selecting a replacement.
FAQ
- Can I replace Group 24 with Group 34?
- Only if terminal positions match and the battery box has 0.9″ extra length. Group 34 provides higher CCA but may require modified hold-down brackets.
- Do Group 24 batteries fit Tesla accessory systems?
- No – Tesla uses proprietary lithium packs. Group 24 may work for aftermarket accessories if isolated from the main drive system.
- How long do marine Group 24 batteries last?
- 4-7 seasons with proper maintenance. Saltwater environments reduce lifespan by 30% compared to freshwater use. Monthly voltage checks are critical.
