In short: a 12-volt automotive battery is required. If your Malibu has the Start-Stop system, you’ll need an AGM (absorbed glass mat) battery; otherwise a conventional flooded lead-acid battery will usually suffice. The common replacement group size for many 2017 Malibu models is H6 (also sold as 48), with CCA ratings that vary by trim and climate. Always verify the exact specs on the battery label or in the owner's manual.
This article lays out the options you’re likely to encounter, how to identify the right battery for your car, and practical tips for replacement and maintenance.
Battery types and configurations in the Malibu
Understanding the two main battery options helps you pick the right one for your Malibu’s equipment:
- Conventional flooded lead-acid (sealed, maintenance-free) batteries are standard on many Malibu trims without Start-Stop. They’re typically less expensive and widely available.
- Absorbed Glass Mat (AGM) batteries are used on Malibu models equipped with Start-Stop. AGM batteries handle frequent restarts, offer robust performance in cold weather, but cost more and require compatible charging and accessories.
- Group size and labeling: GM vehicles commonly use a Group Size such as H6 (often listed as 48 on some batteries). The exact size and whether the battery is AGM or flooded are printed on the battery label. The OEM spec (or your service manual) should be followed for best compatibility.
Concluding note: verify the label on your current battery or consult the owner's manual to confirm whether your 2017 Malibu uses a conventional flooded battery or an AGM, and what group size and CCA rating are required for your trim and climate.
How to verify the right battery for your car
To ensure you buy the correct replacement, follow these steps:
- Locate the existing battery in the engine bay and read the label for the group size (such as H6/48), CCA rating, RC (reserve capacity), and whether it’s an AGM designation.
- Check the Chevrolet Malibu owners manual or GM service information for the recommended battery type and group size for your specific trim and market.
- Determine if your vehicle has Start-Stop. If so, plan for an AGM battery with the appropriate CCA and capacity; otherwise a conventional flooded battery may be appropriate.
- Compare replacement options (OEM/GM-approved or reputable aftermarket), ensuring the chosen battery matches or exceeds the OEM specs (group size, CCA, RC, and AGM vs. flooded).
- Confirm physical fit: verify the battery dimensions, terminal layout (positive/negative), and venting to ensure compatibility with the tray and wiring harness.
- Consider battery registration if your vehicle’s charging system requires it. Some GM vehicles need the new battery to be registered with the body control module to optimize charging behavior; check with a dealer or qualified technician.
Concluding note: after installation, dispose of the old battery properly at an approved recycling facility and reset any electronic systems if instructed by the installer.
Summary
The 2017 Chevy Malibu generally uses a 12-volt automotive battery. If Start-Stop is equipped, an AGM battery is typically required; otherwise a conventional flooded battery is common. Common replacement group sizes for this model are around H6/48, with CCA varying by trim and climate. Always verify the exact specs from the battery label and the owner's manual, and ensure the replacement matches or exceeds OEM requirements. When in doubt, consult a Chevrolet dealer or qualified technician to confirm the correct battery type and installation procedure.
