Jeep Gladiator Battery Specifications
The Gladiator uses a 12V AGM (Absorbent Glass Mat) battery to support its stop-start system and off-road accessories. Off-road duty stresses the battery and charging system — inspection matters.

Battery Care Tips for Your Jeep Gladiator
- Off-road accessories (winches, lights) put heavy load on the battery — inspect terminals and connections regularly.
- Western NC winters drop cranking capacity — load-test annually before cold weather.
- Terminal corrosion is common in off-road Gladiators — inspect seasonally.
- Stop-start requires AGM — never substitute flooded lead-acid.
- Expected lifespan for the AGM battery is 4-6 years.
What's Included in Every Battery at Mahon CDJR
Every battery service at Mahon CDJR starts with a free Mopar battery test that measures voltage, cold cranking amps, and internal resistance. If replacement is needed we use the OEM-spec Mopar battery matched to your Jeep Gladiator — including AGM batteries for vehicles with auto start-stop or eTorque. We also test your alternator and starter while we're at it.
Note on Pricing: Battery price depends on group size, CCA rating, and whether your Jeep Gladiator requires an AGM (Absorbent Glass Mat) battery for start-stop or eTorque systems. PHEV models have additional high-voltage battery systems covered by separate warranties. Call (828) 492-2121 for current battery pricing.
