A Series 24 battery typically measures 10.25 x 6.8 x 8.75 inches (LxWxH) and weighs between 40-45 pounds. These dimensions and weight make it compatible with mid-sized vehicles like sedans and small SUVs. Always verify specifications with the manufacturer, as slight variations can occur based on design and electrolyte type.
What Is a Group Size 24 Battery?
How Do Series 24 Battery Dimensions Compare to Other Group Sizes?
Series 24 batteries are smaller than Group 27/31 batteries (12 x 6.8 x 9.4 inches) but larger than compact Group 35 models. Their mid-sized profile balances power and space efficiency, making them ideal for vehicles requiring 550-650 cold-cranking amps (CCA). For example, they occupy 15% less engine bay space than Group 65 batteries while delivering comparable reserve capacity.
| Battery Group | Length (in) | Width (in) | Height (in) |
|---|---|---|---|
| 24 | 10.25 | 6.8 | 8.75 |
| 27 | 12.0 | 6.8 | 9.4 |
| 35 | 9.1 | 6.9 | 8.9 |
This size comparison explains why Series 24 batteries are preferred for vehicles with limited under-hood space but moderate power needs. The 0.5-inch height reduction compared to Group 31 batteries allows better clearance in compact engine compartments. When upgrading, consider both physical dimensions and electrical specifications – a taller battery might interfere with hood closure even if length/width measurements appear compatible.

What Factors Influence Series 24 Battery Weight Variations?
Weight differences (40-45 lbs) stem from plate thickness, electrolyte volume, and casing materials. Flooded lead-acid batteries weigh more due to liquid electrolyte, while AGM variants use fiberglass mats to reduce weight by 10-15%. Higher reserve capacity models add lead plates, increasing mass by 3-5 pounds compared to standard versions.
| Component | Weight Impact | Typical Range |
|---|---|---|
| Lead Plates | +8-12 lbs | 22-28 lbs |
| Electrolyte | +5-7 lbs | 10-12 lbs |
| AGM Matting | -4-6 lbs | 3-5 lbs |
Manufacturers balance these components to meet specific performance targets. Heavy-duty versions designed for diesel engines often approach the 45-pound upper limit through thicker plates (0.125″ vs standard 0.095″). Conversely, lightweight AGM models sacrifice some cycle life for easier handling. Always compare weight specifications when replacing batteries – a significantly lighter battery might indicate reduced lead content and shorter lifespan.
Which Vehicles Require Series 24 Battery Dimensions?
Common applications include Honda Accord (2013-2017), Toyota Camry (2018-2021), and Nissan Altima (2016-2020). Compact trucks like the Ford Ranger (2019+) also use this size. Check your owner’s manual or measure your battery tray – Series 24 fits compartments between 10.1-10.5 inches long and 6.7-7.1 inches wide.
Why Does Terminal Placement Matter for Series 24 Batteries?
Series 24 batteries use JIS (Japanese Industrial Standard) terminals: positive on the right side when facing the label. Improper terminal alignment can cause cable stress or electrical shorts. Some U.S. vehicles require SAE posts – use adapters if necessary. Always confirm polarity (positive/negative position) before installation to avoid system damage.
Can You Use a Series 24 Battery in Marine or RV Applications?
While possible, marine/RV use requires vibration resistance and deeper cycle capability. Opt for dual-purpose Series 24 batteries with thicker plates (2.5-3.0mm vs standard 1.8mm) and reinforced casing. These modifications increase weight by 5-7 pounds but provide 20-30% longer cycle life in high-movement environments.
What Are the Consequences of Installing an Oversized Battery?
Exceeding compartment size stresses mounting brackets, risking terminal contact with hood components. Weight over 50 pounds may exceed factory tray ratings, leading to structural fatigue. Electrical systems designed for 650 CCA could suffer from 800+ CCA batteries due to alternator overload – stick within 10% of OEM specifications.
How to Measure Your Current Battery for Series 24 Compatibility
Use calipers to measure length/width/height within 1/16-inch accuracy. Check labels for BCI group number – if unclear, compare terminals: Series 24 uses Type 3/8-inch top posts. Measure tray clearance – minimum 0.5 inches above battery for venting. Weight verification helps: 40-45 lbs indicates likely Series 24; 35-38 lbs suggests smaller Group 35.
“The Series 24’s 20-hour amp-hour rating (55-70Ah) makes it a sweet spot for modern start-stop systems. While dimensions haven’t changed since 2008, new AGM tech lets these batteries deliver 850 CCA in the same footprint – a 22% power boost over conventional designs.”

FAQs
- Q: Can I replace a Group 35 battery with Series 24?
- A: Only if your tray accommodates the 1.5-inch longer dimensions. Check clearance around fuse boxes and wiring harnesses before upgrading.
- Q: Do Series 24 batteries work in cold climates?
- A: AGM Series 24 models perform best below freezing, maintaining 95% CCA at 0°F vs 80% for flooded types. Look for 650+ CCA ratings in sub-zero regions.
- Q: How long do Series 24 batteries typically last?
- A: Average lifespan is 3-5 years. Flooded types last 3-4 years; AGM versions reach 5+ years with proper maintenance charging.
