What type of battery does a Honda CRV need?

Most Honda CR‑V models rely on a standard 12‑volt automotive battery for starting and running the car’s electrical systems. Hybrid versions add a separate high‑voltage battery for propulsion, while still using a 12‑volt battery for accessories and ignition-related tasks.

Non-Hybrid CR‑V: The 12-Volt Battery

The gasoline-powered CR‑V models use a conventional 12‑volt car battery to start the engine and power electronics such as the infotainment system, lights, and sensors. When replacing, you’ll choose a 12‑volt battery that fits the vehicle’s fitment and meets its electrical specifications.

Below are the main considerations when replacing the 12‑volt battery in a non-hybrid CR‑V.

• Battery type: a 12‑volt lead‑acid automotive battery, typically maintenance‑free (sealed) or flooded lead‑acid.


• Cold Cranking Amps (CCA): choose a rating that meets or exceeds the OEM specification to ensure reliable starting in cold weather.


• Group size and fitment: match the battery’s physical size and terminal layout to the vehicle’s tray and connectors (check the label or owner’s manual for the correct group size).


• Reserve capacity (RC) and overall capacity: higher RC can help electronics stay powered if the engine is off for extended periods.


• Battery type options: an AGM (absorbed glass matt) replacement can offer longer life and better resistance to vibration, but confirm compatibility with your CR‑V’s charging system.


• Warranty and pricing: compare manufacturer or aftermarket warranties and price points for value and reliability.

Bottom line: for non-hybrid CR‑Vs, select a 12‑volt lead‑acid battery that matches Honda’s specs, with the proper group size and adequate CCA for your climate and driving needs.

Hybrid and CR‑V e:HEV: The 12-Volt Battery and the High-Voltage Pack

CR‑V Hybrid models use a separate high‑voltage battery to drive the electric motors, while a 12‑volt battery powers accessories, the vehicle’s computer systems, and startup operations for the hybrid system. Replacement considerations differ mainly in confirming the 12‑volt battery’s compatibility with the hybrid powertrain’s requirements.

Important notes regarding the 12‑volt battery in a hybrid CR‑V include:

• The 12‑volt battery remains a 12‑volt automotive battery, used for auxiliary power and control systems.


• In many markets, the hybrid’s 12‑volt battery is a sealed maintenance‑free type; some regions may use AGM variants—verify the label and OEM guidance.


• Ensure the replacement battery matches Honda’s specifications for CCA, capacity, and physical fit to avoid charging or electrical issues.


• Replacement should follow proper safety procedures; if in doubt, have a qualified technician perform the swap.


• The high‑voltage traction battery pack is a separate component and is not user‑serviceable; maintenance and service are performed by trained technicians.

In short, even in hybrid CR‑Vs, the 12‑volt battery remains essential for the electronics and startup sequence, but the vehicle also relies on its high‑voltage pack for propulsion.

How to Choose and Replace a CR‑V Battery

Whether you drive a non‑hybrid or hybrid CR‑V, the replacement process follows common automotive battery practices tailored to Honda’s specifics. The steps below help you pick the right battery and install it safely.

• Consult the owner’s manual or a dealer to confirm the exact group size, CCA, and type Honda recommends for your model year and trim.


• Decide between a conventional flooded, maintenance‑free, or AGM 12‑volt battery based on climate, vehicle usage, and budget, ensuring compatibility with the charging system.


• Choose a reputable brand with a solid warranty, and verify compatibility with any vehicle features that rely on battery performance (alarm system, idle stop/start, etc.).


• Before removing the old battery, disconnect the negative terminal first, then the positive, and follow safety precautions to avoid sparks or short circuits.


• Install the new battery in the correct orientation, reconnect terminals (positive first, then negative), secure the tray, and apply terminal protection if recommended.


• After installation, reset or relearn any electronics as required (radio codes, clock, etc.), and dispose of the old battery at an authorized recycling point.

Always follow the specific instructions in the owner’s manual and, if you’re unsure, have a certified technician perform the replacement to ensure full system compatibility and safety.

Summary

For most gasoline CR‑V models, you need a standard 12‑volt automotive battery that fits the vehicle and meets the required CCA. Hybrid CR‑Vs also use a 12‑volt battery for auxiliary power, in addition to a high‑voltage traction battery for propulsion. When replacing, verify the correct group size, CCA, and type (flooded, maintenance‑free, or AGM) from Honda’s specifications, and recycle the old battery responsibly. In any case, consult the owner’s manual or a dealer if you’re unsure about the exact battery needed for your year and trim.

How much does a new battery cost for a Honda CRV?

The average cost for a Honda CR-V Battery Replacement is between $227 and $247. Labor costs are estimated between $44 and $65 while parts are typically priced around $183.

What kind of battery does a 2017 Honda CRV take?

The 2017 Honda CR-V typically uses a Group 51R battery, although some may use a Group 47 (H5) battery, especially if equipped with a stop-start system. When purchasing a battery, it's best to confirm with a battery finder tool to ensure the correct fit, or use an AGM (Absorbed Glass Mat) battery for models with start-stop technology.
 
Common battery types

• Group 51R: This is the most common battery type for the 2017 CR-V. 
• Group 47 (H5): Some models, particularly those with stop-start technology, may use a Group 47 (H5) battery. 
• AGM (Absorbed Glass Mat): For models with a stop-start system, an AGM battery is often recommended due to its ability to handle frequent engine restarts. 

How to choose the right battery

• Check your owner's manual: This will confirm the specific battery type for your vehicle. 
• Use a battery finder tool: Many auto parts websites have tools that will find the correct battery based on your vehicle's make and model. 
• Match the specifications: Whether you choose a 51R or 47/H5, ensure the battery has sufficient Cold Cranking Amps (CCA) and Reserve Capacity (RC) for your vehicle's needs. 

What kind of battery is in a Honda CRV?

The Honda CR-V battery type varies by model year, but most commonly uses a BCI Group 51R battery, while some newer models may use a Group 47 or Group 35 battery. To ensure you get the right battery, always verify the required group size, voltage (12V12 cap V12𝑉), and specifications like Cold Cranking Amps (CCA) for your specific vehicle year, make, and model.
 
Common battery types by model year

• Older models (pre-2014): Often use BCI Group 51R. 
• Recent models (2014 and newer): May use Group 51R, but can also use Group 35 or Group 47, depending on the specific trim and options. 

How to choose the correct battery

• Check your owner's manual: This is the most reliable source for your vehicle's specific requirements. 
• Use a battery finder tool: Many auto parts websites have tools where you can enter your CR-V's year, make, and model to see compatible options. 
• Match the BCI group size: Look for the BCI group size (e.g., 51R, 47, 35) on your current battery or in your owner's manual to find a direct replacement. 
• Consider Cold Cranking Amps (CCA): Choose a battery with at least the recommended CCA for your vehicle, especially if you live in a cold climate. You can often opt for a higher CCA for better performance. 
• Confirm terminal location: Ensure the new battery has the positive and negative terminals in the correct positions (e.g., top left and top right) for your CR-V's cables.
