What Battery Size Fits A Honda CR-V?
The Honda CR-V typically uses a 45Ah (12V) Yuasa 46B24LS battery for gasoline models. This maintenance-free flooded calcium battery measures 207mm(L) x 175mm(W) x 175mm(H), with a CCA rating of 330A. Hybrid versions may require a larger AGM battery due to start-stop systems. When replacing, prioritize the original JIS B24 size group with L terminal orientation.
Fasta Power Battery Products Overview
Is the battery size different between Honda CR-V generations?
The physical battery dimensions remain consistent across CR-V generations (207x175x175mm). However, 2017+ models with auto start-stop may require enhanced AGM batteries with 550-650 CCA for increased electrical demands.
Since 2007, most CR-Vs share the JIS B24 case size despite varying battery technologies. The critical upgrade occurred in 2017 when Honda introduced:
- Absorbent Glass Mat (AGM) batteries for start-stop systems
- Increased reserve capacity (55-65Ah vs original 45Ah)
- Upgraded charging algorithms
The 46B24LS remains compatible for older models, but 2020+ hybrids use a unique lithium-based auxiliary battery.
How does climate affect CR-V battery selection?
Cold climates demand higher Cold Cranking Amps (CCA). For CR-Vs in sub-0°F regions:
| Climate Zone | Recommended CCA | Chemistry |
|---|---|---|
| Arctic (-30°C) | 450+ | AGM/EFB |
| Temperate | 330-400 | Flooded Calcium |
Tropical areas prioritize reserve capacity – 45Ah remains sufficient unless using aftermarket electronics. Always check battery date codes (last digit=year, A-L=month) for freshness.
Can I upgrade to a higher capacity battery?
Upgrades require verifying these factors:
- Tray dimensions (max height 175mm)
- Charging system output (CR-V alternators average 90-120A)
- BMS compatibility for AGM/SLI types
Possible safe upgrades:
- 55Ah AGM (+15% capacity)
- EFB (Enhanced Flooded Battery) with 600 CCA
- Lithium Iron Phosphate (LiFePO₄) for weight reduction
What’s the expected service life?
Original Yuasa batteries typically last:
- 3-5 years in moderate climates
- 2-4 years in extreme temperatures
- 5-7 years for AGM versions with proper maintenance
Signs of failure include:
- Slow engine crank (>3 seconds)
- Voltage below 12.4V when engine off
- Corrosion on terminals (white/green deposits)
How to maintain CR-V batteries?
Use monthly:
- Clean terminals with baking soda solution
- Check electrolyte level (distilled water only)
- Test voltage (12.6V=charged)
Smart charger maintenance every 6 months prevents sulfation. For infrequent use, disconnect negative terminal to prevent parasitic drain.

FAQs
Do hybrid CR-Vs need special batteries?
Yes – hybrids use both a 12V auxiliary battery (typically 20-30Ah AGM) and high-voltage lithium packs. Never interchange these systems.
What Battery Size Fits a Honda CR-V?
For a 2022 Honda CR-V, the recommended battery size is BCI Group 47 (LN2), while models from 2019-2024 often require a BCI Group 51R. Always check your owner’s manual to confirm the size, as it may vary based on model year and engine type.
What is the Best Battery for Honda CR-V?
The best battery for your Honda CR-V depends on factors like climate and driving conditions. A BCI Group 51R battery, like the OPTIMA D51R, is a common option, offering excellent cold-cranking amps (CCA) for reliable starts in cold weather.
How to Find the Right Battery for My Honda CR-V?
Check your Honda CR-V’s owner’s manual for the exact battery size and specifications. You can also inspect the label on your current battery or use an online battery finder tool for compatibility.
Can I Use a Higher CCA Battery for My Honda CR-V?
Yes, using a higher Cold Cranking Amps (CCA) battery is recommended for cold climates, as it provides more power to start your engine in low temperatures. Ensure it fits within your vehicle’s battery compartment.
How Long Do Honda CR-V Batteries Last?
Honda CR-V batteries typically last 3 to 5 years, depending on factors like driving habits, weather conditions, and maintenance. Regularly check the battery’s health to avoid unexpected breakdowns.
What Happens if I Install the Wrong Battery Size in My Honda CR-V?
Installing the wrong battery size can cause performance issues, including improper starting, electrical system damage, or even the inability to close the hood properly. Always use the correct battery size recommended by the manufacturer.
How Much Does a Honda CR-V Battery Cost?
A replacement battery for a Honda CR-V typically costs between $100 and $250, depending on brand, type, and warranty. High-performance batteries with more features, such as longer lifespan or higher CCA, may cost more.
How Do I Maintain My Honda CR-V Battery?
To maintain your Honda CR-V battery, regularly check for corrosion on terminals, ensure it’s securely fastened, and clean it as needed. If you notice any signs of weakness, like dimming lights or slow engine starts, it may be time for a replacement.
