Honda CRV Battery Size
This section is your master reference. The battery group size is the industry standard that defines a battery’s physical dimensions and terminal layout. Using the correct group size guarantees the battery will fit securely in your CR-V’s tray.
First Generation (1997-2001)
The first-gen CR-V, including the 2000 model, uses a 51R battery group size. This is a top-post battery, meaning the terminals are on the top surface.
- Group Size: 51R
- Cold Cranking Amps (CCA): Typically 410-500 CCA
- Terminal Type: Top Post
- Important Note: The “R” in 51R indicates the terminals are in the reverse position. Always get the “R” version for a correct fit.
Second Generation (2002-2006)
For the 2002-2006 models, Honda switched to the 35 battery group size. This is also a top-post battery but with a different footprint than the 51R.
- Group Size: 35
- Cold Cranking Amps (CCA): Typically 500-650 CCA
- Terminal Type: Top Post
Third Generation (2007-2011)
The third generation CR-V continues with the group 35 battery. Specifications remained largely consistent throughout this production run.
- Group Size: 35
- Cold Cranking Amps (CCA): Typically 500-650 CCA
- Terminal Type: Top Post
Fourth Generation (2012-2016)
A significant change arrived with the 2012 model year. Honda introduced a larger, more powerful battery to support increased electrical demands.
- Group Size: 24F (or sometimes listed as 24R)
- Cold Cranking Amps (CCA): Typically 600-750 CCA
- Terminal Type: Top Post
- Key Fact: The 24F is physically larger than the previous group 35. It provides more reserve capacity for accessories.
Fifth Generation (2017-2022)
The fifth-gen CR-V maintained the use of the 24F battery group size. This consistency makes it easy for owners of these popular model years.
- Group Size: 24F
- Cold Cranking Amps (CCA): Typically 600-750 CCA
- Terminal Type: Top Post
Sixth Generation (2023-Present)
The latest CR-V models, starting in 2023, also use the 24F battery. Hybrid models, however, use a separate, smaller auxiliary battery for the computer systems, not for starting.
- Group Size (Gas Models): 24F
- Cold Cranking Amps (CCA): Typically 600-750 CCA
- Terminal Type: Top Post
Quick Reference Chart
Here’s a simple table to save for later.
- 2000-2001: Group 51R
- 2002-2011: Group 35
- 2012-2023 (Gas): Group 24F
Understanding Battery Specifications
Knowing the group size is just the start. Understanding key specifications helps you choose a quality battery that will last.
Cold Cranking Amps (CCA)
CCA measures a battery’s ability to start an engine in cold weather. It’s the number of amps a battery can deliver at 0°F for 30 seconds while maintaining voltage. Higher is generally better, especially in cold climates.
- For CR-Vs: Aim for at least the OEM recommended CCA. Going slightly higher (e.g., 650 instead of 500) is often fine and can provide a safety margin.
Reserve Capacity (RC)
Reserve Capacity indicates how long the battery can run essential accessories if the alternator fails. It’s measured in minutes. A higher RC is a sign of a robust battery.
Terminal Type and Location
Getting this wrong means the cables won’t reach. Most CR-Vs use top-post terminals. Always double-check the terminal orientation (like the “R” in 51R) before purchasing.
How to Replace Your Honda CR-V Battery
Replacing the battery yourself is straightforward. Follow these steps for a safe and successful swap.
- Gather Tools: You’ll need gloves, safety glasses, a wrench set (usually 10mm), and a new battery. A memory saver device is optional but helpful to preserve radio codes and settings.
- Park Safely: Park on a level surface, turn the engine off, and engage the parking brake. Put the transmission in Park (or first gear for manual).
- Locate the Battery: Open the hood. The battery is in the engine bay on the driver’s side for all model years.
- Disconnect the Negative Terminal: Always disconnect the negative (black, “-“) cable first. Loosen the nut and carefully twist the clamp off. Tuck the cable away from the battery terminal.
- Disconnect the Positive Terminal: Next, disconnect the positive (red, “+”) cable in the same manner.
- Remove the Hold-Down Clamp: A bracket or clamp secures the battery base. Remove the bolts or nuts holding it and set the clamp aside.
- Lift Out the Old Battery: Batteries are heavy (30-40 lbs). Lift straight up with your legs, not your back. Place it on a stable surface.
- Clean the Tray and Cables: Use a wire brush and a baking soda/water mix to clean any corrosion from the tray and battery cable terminals.
- Install the New Battery: Carefully lower the new battery into the tray, ensuring it’s oriented correctly (terminals on the proper sides).
- Secure the Hold-Down: Re-install the hold-down clamp or bracket. A snug fit prevents vibration damage, which is a major cause of battery failure.
- Connect the Positive Terminal: Attach the positive cable first this time. Tighten the nut securely.
- Connect the Negative Terminal: Finally, attach the negative cable and tighten it. Give the terminals a light wiggle to ensure they are on there good.
- Test and Reset: Start the vehicle. You may need to reset your clock, radio presets, and window auto-up function. Consult your manual for specific reset procedures.
Choosing the Right Battery Brand
Not all batteries are created equal. Sticking with reputable brands often means better warranties and more reliable performance.
OEM vs. Aftermarket
Original Equipment Manufacturer (OEM) batteries from Honda are high quality but can be expensive. Aftermarket brands like Interstate, DieHard, Optima, and Duralast offer excellent alternatives, often with better warranties.
Warranty Considerations
Pay attention to the warranty. It has two parts: a free replacement period (e.g., 3 years) and a pro-rated warranty after that. A longer free replacement period usually indicates a better-built battery.
Maintaining Your CR-V’s Battery
Proper maintenance can extend your battery’s life by several years. Here’s how to care for it.
- Keep It Clean: Regularly check for corrosion on the terminals. Clean any white or blue crusty buildup with a terminal brush and corrosion-removing spray.
- Secure It Tightly: Ensure the hold-down clamp is snug. Excessive vibration shakes the internal plates apart.
- Drive Regularly: Short trips don’t allow the alternator to fully recharge the battery. Take a longer drive at least once a week if your usage is mainly short hops.
- Check Electrical Loads: Avoid leaving accessories on with the engine off for extended periods. This deeply discharges the battery, which is harmful.
- Test It Annually: Have a professional load test your battery every year, especially before winter. This test reveals its true health, not just its voltage.
Troubleshooting Common Battery Issues
If you’re having problems, this quick guide can help you diagnose the issue.
Slow Engine Crank
If the engine turns over very slowly, the battery is likely weak or discharged. First, check the terminal connections are tight and clean. If the problem persists, the battery may need a charge or replacement.
Clicking Sound When Turning Key
A rapid clicking noise usually indicates the battery doesn’t have enough power to engage the starter solenoid. Try jump-starting the vehicle. If it starts, have the battery and charging system tested immediately.
Battery Warning Light On Dashboard
This light usually indicates a charging system problem, not neccessarily a bad battery. The alternator might not be working. This requires prompt diagnosis to avoid being stranded.
Battery Won’t Hold a Charge
If a freshly charged battery dies after sitting for a day or two, you could have a parasitic drain (something drawing power when the car is off) or an internally failed battery that can’t hold a charge anymore.
