2023-2026 Honda Accord Battery Size
1.5T models use Group H6 (48); Hybrid 2.0L models use Group H6 (48). 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.
The current Accord is the simplest of the five to buy for, because one battery covers the whole lineup. The 1.5T and the hybrid's 2.0L both take a Group H6 — Group 48 under the DIN-derived H-series sizing — an AGM unit rated around 760 CCA. No flooded option, no engine-by-engine split. What matters on the hybrid is knowing which battery is which: the car drives on a separate high-voltage pack, while the H6 discussed here is the 12V auxiliary battery, a different component entirely. The two are separate systems, and replacing the 12V does not involve the pack at all.

| 1.5T | H6 (48) | ~760 | AGM | 11th-gen cars use DIN/H-series sizing; verify the installed label before ordering. | Shop ▸ |
| Hybrid 2.0L | H6 (48) | ~760 | AGM | The hybrid 12V auxiliary battery is separate from the high-voltage pack and should remain AGM. | Shop ▸ |
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.
