The 2014 Mazda CX-5 uses a standard 12-volt lead-acid car battery. If your vehicle has the i-Stop start-stop system, Mazda typically specifies an AGM (absorbed glass mat) battery to handle frequent cycling; otherwise a conventional flooded battery is used.
The exact battery size and specification depend on the engine and market. Replacement should match the OEM rating and group size; check the label on the battery or the owner's manual. This article explains how to identify the correct battery, what to look for when replacing, and where to locate it on the CX-5.
Battery type and specifications
Learn the core facts so you can replace or maintain the CX-5 battery correctly:
- A 12-volt automotive battery powers starting, lighting, and electronics in the CX-5.
- Engine and market variants determine whether a conventional flooded lead-acid battery or an AGM battery is used; i-Stop-equipped models typically require AGM.
- The exact battery group size varies by engine and market; common group sizes include 35 or similar, but you must verify the label or manual for your car.
- When replacing, match or exceed the OEM CCA (cold-cranking amps) rating and overall capacity to ensure reliable starts, especially in cold weather.
- Battery orientation and terminal placement should match the original to ensure proper fit and connection.
In practice, the safe rule is to replace with a battery that matches the OEM rating and group size, and to choose AGM if the vehicle has i-Stop or if you need enhanced cycling resilience.
Replacing the battery: what to verify
Before purchasing a replacement, consider these checks to ensure compatibility and reliability:
- Check the battery group size code on the label (for example, 35, 24F, etc.) and verify in the owner’s manual.
- Note the cold-cranking amps (CCA) and reserve capacity (RC) figures; choose a battery with equal or better performance.
- Determine whether your model requires an AGM or a flooded lead-acid battery based on i-Stop configuration.
- Confirm terminal layout and mounting hardware will fit your engine bay and connectors.
- Inspect battery warranty terms and the replacement policy from the supplier or dealer.
With the right specifications, installation is straightforward: disconnect the negative terminal first, remove the old battery, clean the tray, install the new battery, and reconnect terminals in the reverse order.
Locating and confirming the correct size
Where to find the exact battery specifications and how to confirm the correct size:
The battery is typically located under the hood. For precise group size, refer to the label on the battery itself or the CX-5’s owner's manual. If you’re unsure, a Mazda dealer or a trusted automotive parts retailer can pull the exact spec using your VIN.
Summary
Bottom line: The 2014 Mazda CX-5 uses a 12-volt lead-acid battery. Models with i-Stop may require an AGM battery, while non-i-Stop models use a conventional flooded battery. The precise group size and CCA rating depend on engine and market, so always verify via the battery label or the owner's manual before replacement. When in doubt, consult a dealer or parts professional to ensure you get the right fit.
