What type of battery does a 2007 Honda Accord need?

The 2007 Honda Accord typically uses a 12‑volt BCI Group 51R battery (reverse terminal), and that’s the factory-specified size for most trims, including the 2.4L inline‑four and the 3.0L V6. Look for a battery with at least about 410 cold‑cranking amps (CCA), with higher CCA recommended for cold climates; both conventional flooded lead‑acid and AGM versions are compatible. While some owners upgrade to a physically larger size with tray/bracket changes, 51R is the correct drop‑in fit for stock vehicles. Below are the details to help you pick the right unit and install it confidently.

Factory specifications

The following are the key specifications that match the OEM fitment for a 2007 Accord in North America and ensure proper tray fit, hold‑down, and cable reach.

• BCI group size: 51R (reverse terminal orientation; positive post on the right when facing the front of the vehicle)
• Voltage: 12 V
• Type: Flooded lead‑acid (standard) or AGM (upgrade/optional)
• Recommended CCA: Approximately 410–500+ CCA (choose higher CCA for cold climates)
• Reserve capacity: Typically around 70–90 minutes (varies by brand)
• Approximate dimensions (Group 51R): 9.4 x 5.1 x 8.9 inches (L x W x H)
• Hold‑down: Top clamp style compatible with the factory tray

Sticking to these specs ensures the battery fits the tray, the hold‑down secures properly, and the cables attach without strain.

Engine and trim considerations

Most 2007 Accord variants use the same BCI Group 51R size, but usage and climate can influence the ideal choice within that group size.

• 2.4L I4 (Sedan/Coupe): Group 51R is the standard factory size.
• 3.0L V6 (Sedan/Coupe): Group 51R is also standard and fits the OEM tray and clamp.
• Accord Hybrid (if equipped, 2007 model year): Uses a conventional 12V auxiliary starting battery, typically Group 51R; always confirm under‑hood labeling or the owner’s manual.
• Cold climates: Favor higher CCA within the 51R category or an AGM 51R for better cold‑start performance.
• High electrical loads (audio/accessories): Consider an AGM 51R for better cycling tolerance; upsizing to larger groups (e.g., 24F or 35) is possible only with tray/hold‑down and cable modifications.

In short, Group 51R covers virtually all stock 2007 Accord configurations; deviate only if you plan hardware changes.

Compatible examples you can buy

These commonly available models fit the 51R spec and are frequently stocked by national retailers. Exact CCA/RC ratings vary by brand and model line.

• Interstate MT‑51R or MTP‑51R (flooded; higher CCA on MTP line)
• DieHard Gold/Platinum 51R (Sears/Advance Auto; Platinum often AGM)
• EverStart Maxx 51R (Walmart; usually 500+ CCA)
• NAPA Legend 751R (flooded) or NAPA AGM 51R
• Optima YellowTop D51R (AGM; deep‑cycle/starting hybrid)
• Costco/Interstate 51R (club store variant; good value and warranty)

Match the group (51R), confirm terminal orientation, and choose the performance tier (CCA/AGM) that suits your climate and usage.

How to confirm fitment

If you’re unsure about your trim or suspect prior modifications, these quick checks help verify you’re buying the right battery.

1. Check the owner’s manual or the battery decal under the hood for the BCI group size (51R).
2. Verify terminal orientation: the positive post should sit on the right when the battery is installed and you’re facing the engine bay from the front.
3. Measure your current battery and compare to 51R dimensions to confirm tray and clamp fit.
4. Use a reputable parts lookup with your VIN to double‑check cataloged fitment.
5. Inspect cables and hold‑down hardware; evidence of adapter brackets may indicate a non‑standard size was fitted previously.

These steps prevent buying the wrong case size or terminal layout, saving time at the parts counter.

Installation and ownership tips

Proper installation and maintenance will extend battery life and help avoid nuisance issues like lost radio presets.

• Use a memory saver if you want to retain radio presets and clock; some Accords may prompt for radio security code after loss of power.
• Clean terminals and apply dielectric grease or anti‑corrosion spray before reconnecting.
• Connect positive (+) terminal first, then negative (−); remove in the reverse order.
• Secure the top clamp firmly so the battery cannot move; avoid overtightening terminal clamps.
• After installation, start the engine and let it idle; brief idle relearn may occur as the ECU stabilizes.
• No battery “registration” procedure is required on a 2007 Accord.

These simple steps help ensure reliable starting and protect the vehicle’s electrical system.

Summary

The correct replacement battery for a 2007 Honda Accord is a 12‑volt BCI Group 51R with reverse terminals. Choose at least ~410 CCA (more for cold climates), and consider an AGM 51R for durability or higher demand. This group size fits the factory tray and hold‑down across most trims—including 2.4L I4, 3.0L V6, and typically the Hybrid’s 12V system—while larger sizes require hardware changes. Verify with your manual or VIN if in doubt.

Honda vehicles typically require either lead-acid or AGM (Absorbent Glass Mat) batteries.

What size battery is in a 2007 Honda Fit?

Size is the biggest factor to consider when shopping for a car battery because it determines whether or not it will fit under the hood and provide enough voltage to start the engine. For this reason, a 2007 Honda Fit car battery replacement should belong to group size 151R.

What kind of battery does a Honda Accord take?

The Honda Accord typically uses either a Group Size 51R, 35, or 24F battery, depending on the model year and engine. Some newer models, like the 2018 Accord Hybrid, may use an H6 or H5 battery. 
Here’s a more detailed breakdown:

• 4-Cylinder Models: Often use a Group Size 51R battery. 
• V6 Models: May use a Group Size 35 battery. 
• 2018+ Models: Some may use an H6 or H5 battery. 
• Hybrid Models: May use an OPTIMA H6 YELLOWTOP or similar. 
• General Recommendation: A Group Size 24F battery can be used as a larger, more readily available alternative in some cases. 
• AGM Batteries: Many Honda Accords can also use AGM (Absorbent Glass Mat) batteries, which are a type of lead-acid battery.
