What Are the Dimensions of a Group 78 Battery?
Group 78 batteries typically measure 10.25 inches in length, 7 inches in width, and 7.75 inches in height. This standardized sizing ensures compatibility with battery trays in vehicles designed for this group. Weight ranges between 35-45 pounds depending on construction, with post positions offset to prevent installation errors in approved applications.
Which Vehicles Use Group 78 Batteries?
Common applications include Honda Accord (2008-2017), Toyota Camry (2012-2019), Ford Fusion (2013-2020), and select Nissan Altima models. These batteries suit vehicles requiring SAE BCI Group 78 specifications with 12V systems, typically powering engines up to 3.5L displacement. Always verify compatibility via manufacturer specifications or cross-reference tools before installation.

What Features Define a Group 78 Battery?
Key features include spiral-cell or flat-plate AGM designs, calcium-alloy grids for reduced corrosion, and absorbent glass mat separators. Advanced models incorporate state-of-charge indicators, vibration-resistant casings, and dual-purpose capabilities for start-stop systems. Cold Cranking Amps (CCA) typically range 600-800, with Reserve Capacity (RC) between 90-120 minutes for sustained electrical supply.
How Does Temperature Affect Group 78 Battery Performance?
Performance degrades by 35-50% at 0°F compared to 80°F ratings. High temperatures accelerate fluid evaporation and plate corrosion. AGM variants maintain 85% efficiency in -30°F to 140°F ranges through recombinant technology. Thermal management systems in modern vehicles optimize operating temperatures, extending service life in extreme climates when paired with appropriate battery chemistry.
What Are the Cost Factors of Group 78 Batteries?
Pricing ranges from $120-$300 based on technology: flooded ($120-$180), AGM ($200-$300), lithium hybrid ($400+). Lifespan varies accordingly: 3-5 years for flooded, 5-7 years AGM, 8-10+ years lithium. Total cost of ownership analysis shows AGM providing 25% better value despite higher upfront costs when factoring in replacement frequency and maintenance requirements.
The cost structure reflects technological advancements in plate composition and electrolyte formulations. AGM batteries now feature 15% thicker lead plates compared to 2015 models, increasing material costs but improving cycle life. Installation expenses vary by vehicle complexity – some European models with battery management systems require dealer programming ($75-150 labor cost). Warranty differences significantly impact long-term costs, with premium AGM models offering 48-month free replacement periods versus 18-36 months for standard flooded batteries.
| Battery Type | Average Cost | Expected Lifespan |
|---|---|---|
| Flooded Lead-Acid | $120-$180 | 3-5 years |
| AGM | $200-$300 | 5-7 years |
| Lithium Hybrid | $400+ | 8-10+ years |
“Modern Group 78 batteries now incorporate smart diagnostics directly in the posts. We’re seeing 30% faster charging through graphene additives and self-regulating electrolytes that automatically adjust viscosity based on temperature. These innovations address the growing power demands of advanced driver-assistance systems while maintaining backward compatibility.”

FAQs
- How long do Group 78 batteries typically last?
- Average lifespan ranges 3-5 years for standard flooded batteries, 5-7 years for AGM variants, and 8-10+ years for lithium hybrids. Actual longevity depends on usage patterns, maintenance, and environmental conditions.
- Can I upgrade to an AGM Group 78 battery?
- Most vehicles post-2010 support AGM upgrades if the charging system provides voltage regulation between 14.4-14.8V. Consult your owner’s manual or dealer service department to confirm compatibility before upgrading.
- What’s the proper disposal method for old batteries?
- Return used batteries to authorized retailers or recycling centers. Most states mandate core charge refund programs. Never dispose in regular trash due to lead and acid content – improper disposal may incur fines up to $10,000 under RCRA regulations.
