4-cyl 2.4L models use Group 51R; V6 3.5L models use Group 24F. Battery fit is the same for every year in this generation — always confirm against the
installed battery label, owner's manual, or a VIN-based retailer lookup before ordering.
On 2008–2012 Accords, the 2.4L four-cylinder is the fitment that matters — it is the high-volume version of the car, and it specs a Group 51R rated 500 to 590 CCA in flooded or AGM form. Note the numbers: that floor sits higher than the 435 CCA that passed on the previous generation, so a bargain 51R rated in the 400s technically fits the tray while missing the spec. The 3.5L V6 goes its own way with a Group 24F near 700 CCA. Watch the rating more than the group on these; 500 CCA is the line, and some batteries on the shelf sit under it.

What size battery does a 2008-2012 Honda Accord take?
Across 2008-2012 (8th gen), fitment is set by engine, not by year — every model year in this range shares the same battery. 4-cyl 2.4L models use Group 51R; V6 3.5L models use Group 24F. Confirm the exact group size on the label of your current battery or with a VIN-based retailer lookup before buying.
How many CCA does a 2008-2012 Honda Accord battery need?
Match or exceed the factory rating. For this generation, common fitments are 51R at 500-590 CCA and 24F at ~700 CCA. Higher CCA in the same group size is fine; the wrong physical group size is not.
Should a 2008-2012 Honda Accord use AGM or flooded?
Use the chemistry your car was designed for. Older gas Accords can often run flooded or AGM in the correct group size, while newer start/stop, Touring, and hybrid trims should stay AGM if they came with AGM.
Is a specific model year — like a single 2008 car — different?
No. Every 2008-2012 Accord in this generation uses the same group size and CCA for a given engine, which is why one page covers the whole range instead of a near-identical page per year.
