Full specifications by generation

The battery on a Honda Accord is set by its generation, not its model year, so each generation has one page carrying the complete figures, part numbers and fitment notes for every year it covers.

Honda Accord battery: common questions

What size battery does a Honda Accord take?

BCI group 47 (H5/LN2). Group size is a physical dimension and terminal-position standard, so a battery from a different group may not clamp down or may put the terminals on the wrong side.

Does the Honda Accord need an AGM battery?

The factory battery is an EFB type. Match the type when you replace it.

Where is the battery on a Honda Accord?

Engine bay, driver side.

Does a Honda Accord need the battery registered after replacement?

Both the 1.5T and the hybrid use the DIN H5 (Group 47) format; parts retailers list H5 EFB/AGM fitments for all 2023+ trims. AGM is a worthwhile upgrade for stop-start duty.
