A Group 24 battery typically weighs between 40–60 pounds, depending on its type and chemistry. Flooded lead-acid batteries are heavier (50–60 lbs), while AGM variants weigh 45–55 lbs. Lithium-ion Group 24 batteries are lighter, averaging 20–30 lbs. Weight varies based on capacity, plate thickness, and materials. Always check manufacturer specs for precise details.
What Is a Group Size 24 Battery?
What Factors Influence the Weight of a Group 24 Battery?
The weight of a Group 24 battery depends on its chemistry, capacity, and construction. Lead-acid batteries use thick lead plates and liquid electrolytes, adding mass. AGM batteries replace liquid with fiberglass mats, reducing weight slightly. Lithium-ion models use lightweight lithium compounds. Higher amp-hour (Ah) ratings increase weight due to additional materials. Case durability and terminal type also contribute marginally.
Plate thickness plays a critical role in lead-acid variants – deep-cycle batteries with thicker plates can weigh 15% more than starter batteries of the same group size. Electrolyte volume differences between flooded (1.5-2 gallons) and AGM (absorbed in mats) account for 5-8 lb variations. Lithium batteries achieve weight savings through advanced chemistry, using lithium iron phosphate (LiFePO4) cells that are 70% lighter than equivalent lead plates. Case materials like polypropylene add 2-3 lbs compared to thinner ABS plastic enclosures, while corrosion-resistant terminals contribute up to 1 lb difference between models.

How Does a Group 24 Battery Compare to Other Group Sizes?
Group 24 batteries (10.25″ L x 6.8″ W x 8.9″ H) weigh less than larger groups like Group 27 (55–70 lbs) but more than compact sizes like Group 35 (32–45 lbs). Their balance of capacity (70–85 Ah) and weight makes them ideal for mid-sized vehicles. Lithium variants narrow this gap, offering Group 27-like capacity at Group 35 weights.
| Battery Group | Lead-Acid Weight | Lithium Weight | Typical Capacity |
|---|---|---|---|
| Group 24 | 45-60 lbs | 20-30 lbs | 70-85 Ah |
| Group 27 | 55-70 lbs | 25-35 lbs | 85-105 Ah |
| Group 35 | 32-45 lbs | 15-25 lbs | 45-65 Ah |
Why Choose a Group 24 Battery for Marine Applications?
Group 24 marine batteries provide optimal power-to-weight ratios for boats. Flooded types offer affordable deep cycling (50–60 lbs), while AGM handles vibration better at 45–55 lbs. Lithium models (20–30 lbs) excel in weight-sensitive setups, doubling usable capacity versus lead-acid. Their 2000+ cycle life outperforms traditional options, despite higher upfront costs.
Marine environments demand exceptional vibration resistance – AGM batteries withstand 3x more shock than flooded models due to their immobilized electrolyte. Saltwater corrosion resistance is enhanced in marine-specific Group 24 batteries through thicker terminal coatings and stainless steel hardware. Dual-purpose models combine starting capabilities (800-1000 CCA) with 20% depth-of-cycle tolerance, making them ideal for powering trolling motors while maintaining engine starting reliability. Properly maintained Group 24 marine batteries can provide 5-7 seasons of service in moderate climates.
When Should You Upgrade to a Lithium Group 24 Battery?
Consider lithium when weight savings exceed 50% (20–30 lbs vs 50+ lbs), cycle life exceeds 2000 charges, or fast charging is needed. Ideal for RVs, marine use, and off-grid systems where space/weight matter. Though 3x pricier upfront, lithium lasts 8–10 years versus 3–5 for lead-acid, with zero maintenance.
Who Benefits Most From Group 24 Battery Weight Savings?
Boat owners gain hull-speed efficiency from weight reduction. RVers improve fuel economy and payload capacity. Off-grid solar users maximize power density. Emergency backup systems benefit from easier installation. Performance vehicles shed pounds for acceleration. Lithium’s 50–70% weight cut helps all users except those needing ultra-low-cost solutions.
“The shift toward lithium in Group 24 applications is accelerating. While lead-acid still dominates budget markets, lithium’s weight savings and lifespan now justify costs for 60% of marine and RV users. We’re seeing 25% annual growth in lithium Group 24 sales as users prioritize long-term value over initial price.” — Energy Storage Industry Analyst
Conclusion
Group 24 batteries weigh 40–60 lbs (lead-acid/AGM) or 20–30 lbs (lithium), balancing power and portability. Selection depends on application needs, budget, and performance priorities. Lithium’s lightweight advantages redefine traditional tradeoffs, making Group 24 a versatile choice across automotive, marine, and renewable energy sectors.
FAQs
- How long does a Group 24 battery last?
- Flooded: 3–5 years. AGM: 4–6 years. Lithium: 8–10 years. Cycle life ranges from 300–500 (lead-acid) to 2000+ (lithium). Proper maintenance extends lifespan.
- Can I replace a Group 24 with a smaller battery?
- Only if the smaller battery meets your vehicle’s CCA (cold cranking amps) and Ah requirements. Undersizing risks power shortages and reduced lifespan.
- Are all Group 24 batteries dual-purpose?
- No. Some are starter-only (thin plates) or deep-cycle-only (thick plates). Dual-purpose models balance both but compromise on specialization.
