Quick Answer

• BCI Group Size: H7 (also known as Group 94R)
• CCA Rating: 700-800 CCA is recommended for optimal starting power.
• Reserve Capacity: 130-150 minutes RC
• AGM vs. Flooded: The 2016 Grand Cherokee can use either, but AGM is highly recommended for its superior performance and longevity.
• Terminal Layout: Top post, typically positive on the right (SAE posts).
• Physical Dimensions: 12.4" L x 6.9" W x 7.5" H (315mm x 175mm x 190mm) – varies slightly by manufacturer.
• Dual-Battery Setup: Not applicable for the gasoline model; diesel models may have a larger single battery or a different setup, consult your owner's manual.

Replacement Battery Options

Here are some popular and reliable replacement battery options for your 2016 Jeep Grand Cherokee:

• Interstate: MTZ-94R/H7 (AGM) or MTP-94R/H7 (Flooded)
• Optima: YellowTop H7 (AGM - 8003-251)
• DieHard: Platinum AGM H7 (check current part numbers with retailer)
• Odyssey: ODP-AGM94R H7 (AGM)
• ACDelco: 94RAGM (AGM) or 94R Advantage (Flooded)

AGM vs. Flooded — Which Does This Vehicle Need?

While your 2016 Jeep Grand Cherokee originally came with a flooded lead-acid battery, an Absorbed Glass Mat (AGM) battery is strongly recommended for replacement. Modern vehicles like the Grand Cherokee place higher demands on their electrical systems due to numerous electronic components (infotainment, safety features, engine control units, etc.).

AGM batteries offer several advantages over traditional flooded batteries:

• Improved Durability: More resistant to vibration and impacts, ideal for a vehicle that might go off-road.
• Longer Lifespan: Generally last longer than flooded batteries under similar conditions.
• Deeper Cycle Capability: Better suited for vehicles with start-stop technology (though the 2016 Grand Cherokee typically doesn't have this, it benefits from the robust design).
• Maintenance-Free: No need to check water levels.
• Enhanced Performance: Provides more consistent power output and excellent cold-cranking performance, especially beneficial in harsh weather.

Considering the relatively small price difference for the long-term benefits, an AGM battery is a worthwhile upgrade for your Grand Cherokee.

Post-Installation Relearn / Reset Procedure

After replacing the battery in your 2016 Jeep Grand Cherokee, it's a good idea to perform a basic reset to allow the vehicle's computer systems to recalibrate. While not always strictly necessary for basic function, it can help prevent minor electrical glitches or erroneous dashboard warnings.

1. Install the new battery: Ensure terminals are clean and connections are tight.
2. Turn the ignition to the "ON" position (without starting the engine): Leave it in this position for about 10-15 seconds.
3. Turn the ignition to the "OFF" position: Leave it off for 10-15 seconds.
4. Start the engine: Allow it to idle for a few minutes. The engine control unit (ECU) will begin to re-learn its idle parameters.
5. Drive the vehicle: Drive the Grand Cherokee for a short period (10-15 minutes) with varying speeds and stops. This helps the transmission and other systems recalibrate.

Some owners report that power windows might need to be "relearned" by rolling them all the way down and then all the way up, holding the switch for a few seconds at each extreme. Radio presets and clock settings will also need to be re-entered.

Signs of a Failing Battery

Don't wait for your battery to die completely. Look out for these common signs that your 2016 Grand Cherokee's battery is on its way out:

• Slow Engine Crank: The engine struggles to turn over, especially in cold weather.
• Dim Headlights or Interior Lights: Lights appear dimmer than usual when the engine is off or idling.
• Warning Lights: A battery or charging system warning light appears on your dashboard.
• Corrosion on Terminals: White or blue powdery substance around the battery terminals can indicate a poor connection or an aging battery.
• Swollen Battery Case: The battery case looks expanded or bulging, often a sign of overheating or overcharging.
• Electrical Gremlins: Unexplained issues with electronics, such as intermittent radio operation or flickering dash lights.

Common Battery Issues for This Generation

Owners of the 2016 Jeep Grand Cherokee occasionally report parasitic draws as a cause of premature battery drain. This means something in the vehicle continues to draw power even when the vehicle is off, slowly depleting the battery. Common culprits can include:

• Failing door lock actuators
• Malfunctioning infotainment systems or modules
• Aftermarket accessories that are improperly wired
• Glove box or under-hood lights staying on

If you experience repeated battery drains even with a relatively new battery, it's advisable to have a professional diagnose the parasitic draw. Additionally, ensure your alternator is functioning correctly, as a failing alternator can lead to undercharging and a dead battery.
