Battery finder
Select your Accord year and engine. Each size is the replacement battery Honda's parts catalog lists for it (part numbers in the chart below); confirm against the label on your battery before buying.
Check for the R on your current label: 51 and 51R put the terminals on opposite sides.
See recommended batteriesHonda's parts catalog lists a Group 51R battery, part 31500-SR1-100M, for the 2013-2017 Accord with the 2.4-liter four-cylinder. The 3.5-liter V6 gets a Group 24F, part 31500-TK8-A2100M, rated at 630 CCA. The Accord Hybrid is where people go wrong. Its 12-volt battery is a Group 51, not a 51R, Honda part 31500-SB2-100M. The two are mirror images with the terminals on opposite sides, so the 51R from the gas car won't do. Honda sold the hybrid for 2014, 2015 and 2017, with no 2016 model. On some 2014 hybrids the catalog also shows a 46B24R battery, part 31500-T3V-A02, so look at the label on the one that's installed before ordering.
