Full specifications by generation
The battery on a Jeep Wrangler 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.
Jeep Wrangler battery: common questions
What size battery does a Jeep Wrangler take?
- BCI group 48 (H6) with stop-start-equipped engines; 94R (H7) on engines without stop-start. 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 Jeep Wrangler need an AGM battery?
- Yes. This vehicle requires AGM, not flooded. A flooded battery in a start-stop system is cycled far harder than it is designed for and fails early.
Where is the battery on a Jeep Wrangler?
- Engine bay, driver side (except 4xe. See hybrid engine entry for its separate 12V/HV setup).
Does a Jeep Wrangler need the battery registered after replacement?
- JL moved from the JK's flooded Group 34 to a larger AGM battery. Which group fits depends on whether the specific engine/trim has engine stop-start. Confirm before ordering a replacement.
