Battery Care Tips for Your Jeep Grand Cherokee
- 4xe owners: the 12V battery still needs occasional charging if vehicle sits unused.
- HEMI eTorque systems have an auxiliary battery — inspect both during service.
- Western NC winters drop cranking — load-test annually.
- Inspect terminals seasonally.
- Expected lifespan for AGM batteries 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 Grand Cherokee — 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 Grand Cherokee 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.
