This is the high-volume Accord fitment: Group 51R with reversed terminals.
See recommended batteriesOn 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 to check before buying
- Group size: this controls physical fit, hold-down, and terminal position.
- Terminal direction: 51R has reversed terminals; 51 and 51R are not interchangeable.
- CCA: match or exceed the factory rating in the same group size.
- Chemistry: keep AGM if your Accord came with AGM, especially on hybrid or start/stop trims.
