Toyota Battery Group Size Chart: Find the Perfect Fit for Your Ride
You pop the hood of your Toyota, stare at the battery, and realize you have no idea what size you actually need.
Battery group sizes can feel like a secret code, but they’re really just standard measurements that ensure your new battery fits perfectly. This guide breaks down the most common Toyota battery sizes, what they mean, and how to find the right one for your vehicle.
TL;DR
Toyota vehicles commonly use BCI Group Size 35, 24F, 27F, 51R, and 52 batteries . The group size refers to standardized physical dimensions and terminal placement—not battery power. Most sedans and smaller SUVs use Group 35, while larger trucks and SUVs use Group 24F or 27F. Hybrid models often use specialized sizes like Group 52. Always check your owner’s manual or the sticker under your hood before buying.
Key Takeaways
- Group 35 is the most common Toyota battery size—fits Camry, Corolla, RAV4, and Tacoma
- Group 24F/27F fit larger vehicles like Tundra, Sequoia, and older Land Cruisers
- Hybrids often use Group 52 or other specialized sizes
- BCI size doesn’t equal power—Cold Cranking Amps (CCA) and Reserve Capacity matter too
- Always check your current battery for the group size label before buying
What Is a BCI Group Size?
The Battery Council International (BCI) created standardized group sizes so you can easily find a battery that fits your vehicle . Each group size has specific:
- Length, width, and height dimensions
- Terminal placement (which side is positive/negative)
- Terminal type (top post, side post, or both)
The group size doesn’t tell you anything about power—that’s measured separately by Cold Cranking Amps (CCA) and Reserve Capacity (RC).
Toyota Battery Group Size Chart
Here are the most common Toyota battery group sizes based on official Toyota data :
| BCI Group Size | Length (inches) | Width (inches) | Height (inches) | Typical CCA |
|---|---|---|---|---|
| 24 | 10 1/4 | 6 13/16 | 9 | 575 |
| 24F | 10 21/32 | 6 13/16 | 9 | 575 |
| 25 | 9 1/16 | 6 7/8 | 8 7/8 | 550 |
| 27 | 12 1/32 | 6 13/16 | 8 15/16 | 675 |
| 27F | 12 31/64 | 6 13/16 | 8 15/16 | 710 |
| 35 | 9 1/16 | 6 7/8 | 8 7/8 | 550 |
| 51 | 9 3/8 | 5 1/8 | 8 7/8 | 500 |
| 51R | 9 3/8 | 5 1/8 | 8 7 | 500 |
Note: Group 24 and 24F have different terminal placement. The same applies to 27 vs 27F and 51 vs 51R .
Which Toyota Models Use Which Battery Size?
Group 35 – The Most Common Toyota Battery
This is the go-to size for most Toyota sedans, SUVs, and trucks . If you drive a:
- Camry (most years)
- Corolla (most years)
- RAV4 (most years)
- Tacoma (most years)
…you’re likely looking at a Group 35 battery.
Important note: Some Group 35 batteries require a height adapter to properly accommodate the factory battery hold-down .
Group 52 – The Hybrid Special
BCI Group 52 batteries are commonly used in hybrid vehicles, including:
- 2015-2021 Camry Hybrid
- Select Honda and Nissan hybrids
Group 52 specs:
- Dimensions: Approx. 9.5″ L x 7.5″ W x 7.25″ H
- CCA Range: 550-600
- Terminal Type: Top-post with positive terminal on the left
Group 24F and 27F – Larger Vehicles
If you drive a larger Toyota truck or SUV, you’ll likely need a bigger battery:
- Tundra often uses Group 24F or 27F
- Sequoia often uses Group 27F
- Land Cruiser often uses Group 27F
These larger batteries provide more CCA for bigger engines and more reserve capacity for accessories.
Cross-Reference: JIS to BCI Battery Conversion
Toyota vehicles manufactured in Japan use a different standard called Japan Industrial Standard (JIS) . When you’re replacing a JIS battery with a BCI battery, use this cross-reference guide :
| JIS Code | Best-Fit BCI | Notes |
|---|---|---|
| 46B24R | 51 | (BCI 51 is for Scion iQ only; for Prius, use JIS battery) |
| 50D20L | 35 | |
| 50D20R | 25 | |
| 50D23L | 35 | |
| 55B24L | 51R | |
| 55D23L | 35 | May have vent cap clearance problems |
| 55D23R | 25 | May have vent cap clearance problems |
| 65D23L | 35 | |
| 75D31R | 27 | |
| 80D26L | 24F | |
| 80D26R | 24 | |
| 95D31L | 27F | |
| 105D31L | 27F |
“It is advisable to check the size of the battery installed in the vehicle to determine the proper replacement battery.”
How to Find Your Toyota’s Battery Group Size
1. Check the Current Battery
The group size is usually printed on a label on top of the battery. Look for a number like “35” or “24F.”
2. Look Under the Hood
Many Toyotas have a sticker on the underside of the hood or near the battery tray with the recommended battery specifications.
3. Check the Owner’s Manual
The manual includes the recommended battery group size, CCA, and other specs.
4. Use an Online Parts Lookup
Auto parts websites like O’Reilly or AutoZone let you enter your vehicle’s year, make, and model to find the right battery .
Cold Cranking Amps (CCA) Matters Too
Group size tells you the physical fit, but Cold Cranking Amps (CCA) tells you the battery’s starting power . This is the number of amps a battery can deliver at 0°F for 30 seconds while maintaining at least 7.2 volts.
Rule of thumb: More CCA is better for cold climates. If you live in a cold area, get the highest CCA battery that fits your group size.
Toyota CCA ratings by group size :
- Group 24/24F: 575 CCA
- Group 25: 550 CCA
- Group 27: 675 CCA
- Group 27F: 710 CCA
- Group 35: 550 CCA
- Group 51/51R: 500 CCA
AGM vs. Standard Flooded Batteries
Some newer Toyota models with high electrical loads recommend or require AGM (Absorbent Glass Mat) batteries . AGM batteries:
- Handle repeated deep discharges better
- Are more vibration-resistant
- Last longer in stop-and-go driving
- Cost more than standard batteries
Check your owner’s manual—if it says “AGM Recommended,” spend the extra money.
