Ford Mustang battery size by year

Model years Battery group size Type
2005–2014 Group 96R Flooded/AGM
2015–2023 Group 96R or Group 99R Flooded/AGM
2024–2025 Group 48/H6 AGM

More than one size listed? Some years use a different battery depending on engine, trim or options (for example hybrid vs. gas, or start-stop). Match the group number on the label of your current battery, or call (650) 583-6735 and we'll confirm.

AGM vs. flooded: if your Ford Mustang came with an AGM battery (common on start-stop models), replace it with AGM. Otherwise a standard flooded battery works, and AGM is an optional upgrade for longer life.
