2012–2021 Jeep Grand Cherokee Battery Size (BCI Group and CCA)

Which Jeep Grand Cherokee model years does this cover?

These battery specifications apply to every Jeep Grand Cherokee built from 2012 through 2021 — the WK2 (4th generation), mid-size 2-row suv. Nothing in this specification changes between those model years. Pick your year for the engines it offered, what changed that year, and the problems recorded against it.

What size battery does a 2012–2021 Jeep Grand Cherokee take?

BCI group H6/Group 48 (some builds/trims reported as H7/Group 94R), rated at 730 cold cranking amps from the factory. 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.

How many CCA does a 2012–2021 Jeep Grand Cherokee need?

At least 730 CCA. Going higher is harmless and helps in cold climates; going lower is how a vehicle that started fine in October stops starting in January.

Does the 2012–2021 Jeep Grand Cherokee need an AGM battery?

The factory battery is a conventional flooded type. AGM is a valid upgrade, but never downgrade from AGM to flooded.

Where is the battery on a 2012–2021 Jeep Grand Cherokee?

Cabin, under the front passenger seat, move the seat all the way forward to access, not under the hood.

Does a 2012–2021 Jeep Grand Cherokee need the battery registered after replacement?

Group size is inconsistently reported across owner threads (H6/48 vs H7/94R). Very likely varies by build/options package. Confirm the size stamped on your existing battery before ordering a replacement. Diesel and some heavier-optioned builds may spec a larger Group 65/H8 battery. See the EcoDiesel engine entry.
