The “94R” on a battery refers to its group size, a standardized code indicating physical dimensions, terminal placement, and power capacity. Commonly used in vehicles like Honda, Acura, and Toyota, the “R” denotes reversed terminal positions (positive on the right). This code ensures compatibility with specific car models and electrical requirements.
What Is a Group Size 24 Battery?
How Is the 94R Battery Group Size Defined?
The 94R group size specifies a battery measuring approximately 12.4 x 6.9 x 7.5 inches. It features a BCI (Battery Council International) code with reversed terminals, delivering 70-80 Ah (ampere-hours) and 700-800 CCA (cold cranking amps). This standardization ensures fitment in vehicles designed for this configuration, such as hybrid cars and SUVs requiring compact, high-output power sources.
Which Vehicles Use a 94R Battery?
94R batteries are commonly found in Honda Accord Hybrids, Acura MDX, Toyota Camry Hybrids, and select Lexus models. Manufacturers prioritize this group size for its balance of compact design and sufficient power to support start-stop systems, infotainment, and advanced safety features. Always check your owner’s manual or consult a dealer for compatibility.

What Are the Key Specifications of a 94R Battery?
A 94R battery typically provides 750 CCA, 120-minute reserve capacity, and 80 Ah. Its AGM (absorbent glass mat) or EFB (enhanced flooded battery) variants cater to start-stop technology, ensuring durability under frequent cycling. Voltage stabilizers and corrosion-resistant terminals further enhance reliability in modern vehicles.
AGM 94R batteries are particularly favored for their spill-proof design and faster recharge rates. These units can handle up to 3x more charge cycles than standard flooded batteries. For drivers in extreme climates, the following table compares performance metrics:
| Specification | AGM 94R | EFB 94R |
|---|---|---|
| CCA at -18°C | 800 amps | 750 amps |
| Lifespan | 6–8 years | 4–6 years |
| Cycle Resistance | High | Moderate |
“The 94R’s design caters to modern vehicles’ energy demands. Its reverse terminals prevent cable stress, and AGM technology handles regenerative braking in hybrids. Always prioritize OEM specifications—aftermarket alternatives may lack the software integration needed for battery management systems.” – Automotive Electrical Systems Specialist
FAQs
- Can I use a 94R battery in a non-hybrid car?
- Only if the vehicle’s manual specifies this group size. Non-hybrids may lack the charging systems to optimize 94R performance.
- How long does a 94R battery last?
- Average lifespan is 4–6 years, depending on usage, climate, and maintenance. AGM variants often exceed this range.
- Is the 94R more expensive than standard batteries?
- Yes, due to advanced construction. Prices range from $200–$400, but longevity and performance justify the cost.
