What Are The Specs Of A Group 24 Battery?
Group 24 batteries are standardized 12V lead-acid or AGM cells with dimensions around 10.25 x 6.8 x 8.9 inches, commonly used in automotive, marine, and RV applications. They deliver 70–85Ah capacity (flooded) or 80–100Ah (AGM), with CCA ratings of 600–800A. Terminal types include top-post (SAE) or dual terminals, supporting high cranking power for engines and moderate deep cycling. Pro Tip: AGM Group 24 batteries last 2–3x longer than flooded types in vibration-prone setups.
What are the physical dimensions of a Group 24 battery?
A Group 24 battery measures approximately 10.25″ L x 6.8″ W x 8.9″ H, with ±0.25″ variance across brands. This compact size fits most mid-sized vehicle trays, balancing power density and space efficiency. Weight ranges from 40–55 lbs depending on plate thickness and electrolyte type.
Beyond size consistency, Group 24’s design prioritizes universal compatibility. For example, a Marine Master AGM Group 24 battery slots into both bass boats and diesel trucks without tray modifications. Pro Tip: Always measure your existing battery compartment before upgrading—some AGM models have taller terminals requiring spacer rings. Technical specs include:
– Post height: 0.75″–1.25″
– Inter-terminal distance: 7.25″
– Case material: Polypropylene (heat-resistant)
But what if your application demands more reserve capacity? Consider Group 27 (20% larger) or verify if your tray accommodates dual Group 24s in parallel.
What capacity does a Group 24 battery provide?
Group 24 batteries offer 70–100Ah capacity, with 180–240 minute reserve capacity (RC). Flooded versions average 75Ah, while AGM variants reach 95Ah via dense lead grids. High CCA ratings (600–800A) suit cold-cranking needs.
Practically speaking, a 85Ah Group 24 can power a 50L RV fridge for 17 hours without recharge. Pro Tip: For trolling motors, multiply amp-hour rating by 0.8 to estimate real-world runtime—AGM handles deeper discharges better. Chemistry impacts capacity retention; flooded batteries lose 1–2% monthly vs AGM’s 1–3% annually. Example: Two Group 24 AGMs in series create a 24V 90Ah system for solar storage, doubling voltage while maintaining capacity.
| Type | Capacity (Ah) | Cycle Life |
|---|---|---|
| Flooded | 70–85 | 300–500 |
| AGM | 80–100 | 600–1200 |
What terminal configurations do Group 24 batteries use?
Group 24 batteries feature SAE top-post terminals (0.75″ diameter) or dual top/side posts. Marine models often add threaded studs for accessory connections, while automotive focus on cranking amps.
When installing, ensure terminal polarity matches your system—reverse connections can fry electronics. Pro Tip: Apply anti-corrosion gel on terminals; saltwater exposure accelerates erosion by 5x. Example: A dual-terminal Odyssey Group 24MPC powers winches (via side posts) while maintaining starter function through top posts. Warning: Mixing lead-acid and lithium jump starters on terminals risks voltage spikes.

FAQs
Yes, AGM Group 24 handles 50% DoD cycles 600+ times—ideal for solar/RV use. Flooded types limit cycles to 200–300.
How long does a Group 24 last?
3–5 years (flooded) vs 6–10 years (AGM). Temperature extremes shorten lifespan by 30%.
Is Group 24 interchangeable with Group 35?
No—Group 35 is 1″ shorter. Verify tray clearance and terminal positions first.
