Toyota Camry Battery Size and Price Guide: Cost and Specifications

If you searched for Toyota Accord battery size and price, you're probably dealing with a dead or weak battery and need answers fast. Here's the thing the Accord is actually a Honda model, not a Toyota. It's a common mix-up, especially when you're Googling in a parking lot with a car that won't start. But your real question is simple: what battery fits your car, and how much will it cost? That's exactly what we'll cover below, including both Honda Accord and popular Toyota models in case you have one of those instead.

Is the Toyota Accord a Real Car?

No. The Honda Accord has been around since 1976 and is one of the best-selling sedans in the U.S. Toyota makes the Camry, Corolla, and Avalon not the Accord. If you typed "Toyota Accord" into Google, you likely own a Honda Accord or possibly a Toyota Camry. Both are midsize sedans, which is probably where the confusion starts. Regardless of which one you actually drive, the battery information below will help you figure out what you need.

What Battery Size Does a Honda Accord Use?

Battery group size depends on the model year and engine type. Here's a quick breakdown for the most commonly searched Accord years:

2003–2007 Honda Accord (4-cylinder): Group 51R
2003–2007 Honda Accord (V6): Group 24F
2008–2012 Honda Accord (4-cylinder): Group 51R
2008–2012 Honda Accord (V6): Group 24F
2013–2017 Honda Accord: Group 51R (all trims)
2018–2022 Honda Accord: Group 51R (gas models); hybrid models use an AGM battery

The Group 51R is the most common Accord battery. The "R" means the positive terminal is on the right side. Getting the terminal position wrong can cause cable strain or even short circuits, so double-check before you buy.

What Battery Size Do Popular Toyota Models Use?

If you actually own a Toyota and mixed up the name, here are battery group sizes for common Toyota sedans:

Toyota Camry (2012–2017): Group 35 (4-cylinder) or Group 24F (V6)
Toyota Camry (2018–2023): Group 35 or Group 47 (H5)
Toyota Corolla (2014–2019): Group 35
Toyota Corolla (2020+): Group 47 (H5)
Toyota Avalon (2013–2018): Group 24F

Always check your owner's manual or the label on your existing battery before purchasing. You can also look up your exact year and model to find the correct battery group size for a 2005 Toyota model with pricing details.

How Much Does a Replacement Battery Cost?

Prices vary based on brand, battery type (standard flooded vs. AGM), and where you buy. Here's what to expect in 2024:

Group 51R (Honda Accord): $120–$220
Group 24F (Honda Accord V6): $130–$240
Group 35 (Toyota Camry/Corolla): $110–$200
Group 47 / H5 (newer Toyota models): $140–$230
AGM batteries (hybrid or start-stop systems): $180–$350

Walmart, Costco, and AutoZone tend to have the best prices. Dealerships charge more sometimes $250+ for the same battery you'd find for $150 at a retail store. If you want a deeper look at pricing for older models, this breakdown of the cost of a battery for a 2005 model year gives you real numbers.

What Affects Battery Price the Most?

Three things push the price up or down:

Battery type. Standard flooded batteries are cheapest. AGM (Absorbent Glass Mat) batteries cost 30–60% more but last longer and handle extreme temperatures better.
Brand. DieHard, Interstate, and Optima cost more than store brands, but many are made in the same factories. The warranty length is often a better indicator of quality than the brand name.
Where you buy. A dealership install might run $200–$400 total. Buying the battery yourself at Costco and installing it in the parking lot costs $100–$180 total. Most auto parts stores offer free installation with purchase.

Can You Install It Yourself?

Yes, and it's one of the easiest car maintenance tasks. You need a 10mm wrench and about 10 minutes.

Turn off the engine and open the hood.
Disconnect the negative (−) terminal first, then the positive (+).
Remove the battery hold-down bracket.
Lift out the old battery (they weigh 30–45 lbs, so be careful with your back).
Place the new battery in the tray.
Reconnect the positive (+) terminal first, then the negative (−).
Secure the hold-down bracket and close the hood.

On some Honda Accords (especially 2008+), the battery sits in a tight spot. If the terminal bolts are corroded, spray them with a battery cleaner or a mix of baking soda and water before attempting removal.

What Are Common Mistakes People Make?

Buying the wrong group size. A Group 51 and Group 51R are the same dimensions but have opposite terminal positions. Getting this wrong means cables won't reach or could short out.
Ignoring the CCA rating. Cold Cranking Amps matter if you live somewhere with real winters. Aim for at least the minimum CCA listed in your owner's manual more is fine, less is risky.
Not registering the battery. Some newer cars (mainly European, but it's spreading) require you to "register" a new battery through the car's computer. Honda and Toyota generally don't require this, but check if your model has an auto start-stop system.
Forgetting to recycle the old battery. Most stores that sell you a new battery will take the old one for free. Some even give you a $10–$20 core refund if you bring it back.

How Long Should a Car Battery Last?

Most batteries last 3 to 5 years. Heat kills batteries faster than cold, so if you live in Arizona or Texas, expect the lower end of that range. In cooler climates like Minnesota or Maine, you might squeeze out 5–6 years. If your battery is over three years old and you notice slow cranking or dim headlights, have it tested at an auto parts store they'll do it for free.

Quick Checklist Before You Buy

✅ Confirm your exact year, make, model, and engine size not just "Accord" or "Camry"
✅ Check the group size printed on your current battery's label
✅ Note the terminal position (left or right side of the positive terminal)
✅ Compare prices at at least two stores before purchasing
✅ Look for a warranty of 3 years or longer
✅ Bring your old battery for the core refund ($10–$20 back in most cases)
✅ Test the new battery's voltage with a multimeter it should read 12.4V–12.7V before installation

Knowing the right battery group size and a fair price range keeps you from overpaying or buying the wrong part. Check your manual, compare prices, and if the battery is older than three years, test it now before it leaves you stranded.
