A replacement 12-volt battery for a 2018 Mazda CX-5 typically costs between about $90 and $320, depending on the battery type and where you buy it.
The CX-5 uses a 12-volt starting battery, and some trims with Start-Stop technology may require an AGM (Absorbent Glass Mat) battery for optimal performance. Pricing reflects whether you choose a standard flooded lead-acid battery or an AGM battery, as well as the retailer and any installation fees.
What affects the price
Prices vary by battery type, retailer, and warranty terms. The following ranges capture common market offerings and what you can expect to pay.
- Standard flooded 12V battery (non-AGM): typically $90–$150 at auto parts stores; dealer pricing can be $120–$180. A core charge may apply.
- AGM battery (for Start-Stop or higher electrical load): typically $170–$320 at auto parts stores; dealer pricing can be $210–$360. Longer warranties are common with AGM models.
- Battery with extended warranty or premium brands: prices can be higher, often $200–$360 depending on brand and warranty terms.
In practice, choosing AGM or standard, along with where you purchase, drives the total cost. If your CX-5 has Start-Stop, budgeting toward AGM options is prudent for reliability and longevity.
Where to buy
Retail options and typical price expectations vary. The following are common sources for a 2018 CX-5 battery.
- National auto parts stores (AutoZone, Advance Auto Parts, O'Reilly): broad selection with warranty coverage; prices align with the ranges above.
- Mazda dealership: OEM (dealer) batteries, often with installation available; typically higher prices but guaranteed compatibility with your vehicle.
- Online retailers and local garages: can offer competitive pricing; ensure you select the correct group size and confirm whether an AGM is used if your build requires it.
Call ahead for current quotes and verify fitment for your exact CX-5 trim and battery type. Installation and disposal fees may apply at some shops.
Choosing the right battery for your CX-5
To ensure a proper fit, verify the battery’s group size and whether your model requires an AGM battery. Check the owner’s manual or the existing battery's label, and confirm with the retailer that the replacement matches the CX-5's Start-Stop configuration if equipped.
Summary
The cost of a 2018 Mazda CX-5 battery depends largely on battery type (standard vs AGM), retailer, and warranty. Expect roughly $90–$150 for a standard battery, $170–$320 for an AGM battery, with dealer pricing often higher. Installation or core charges can add to the total. For the most accurate quote, contact local parts stores or your Mazda dealer with your vehicle’s trim and, if possible, its VIN.
