The 2016 Cadillac ATS uses a 12-volt automotive battery. If your car is equipped with the Start-Stop system, it typically uses an AGM (absorbed glass mat) battery; models without Start-Stop generally use a conventional flooded lead-acid battery.
Battery types and Start-Stop influence
Two main battery technologies
Owners should know there are two primary battery technologies that appear in the ATS lineup, depending on equipment and options:
- Conventional flooded 12‑volt lead‑acid battery — commonly used in ATS configurations without Start‑Stop or with basic electrical demands.
- Absorbed Glass Mat (AGM) 12‑volt battery — used on vehicles equipped with Start‑Stop or higher electrical loads; provides better crank power and resistance to deep discharge.
In practice, the exact battery type for a given 2016 ATS depends on whether the car has the Start‑Stop feature. If you’re unsure, check the battery label, the owner’s manual, or ask a dealer to confirm the correct type for your vehicle.
How to verify and replace the battery
Practical steps for verification and replacement
To ensure you buy the correct size and type, follow these steps. This list helps you confirm the proper group size, CCA rating, and whether AGM is required.
- Check the owner's manual for the recommended battery group size and specifications for your exact engine and trim.
- Inspect the existing battery label for the group size (the code such as 41, 94R, etc.), the CCA rating, and whether it’s labeled as AGM.
- If your ATS has Start‑Stop, expect an AGM battery; if there’s any doubt, verify with the dealer or GM service information by VIN.
- Choose a replacement that matches the specified group size and meets or exceeds the CCA rating; for Start‑Stop, use an AGM battery from a reputable brand or OEM supplier.
- Consider OEM-grade options such as ACDelco (GM’s preferred supplier) or other reputable brands with the AGM design if required.
Using an incorrect battery type or size can lead to charging issues or electrical glitches, so always verify using your VIN and official documentation before purchase.
Summary
The 2016 Cadillac ATS relies on a 12‑volt battery. Models with Start‑Stop typically require an AGM design, while non‑Start‑Stop configurations use a conventional flooded lead‑acid battery. Verify the exact group size, CCA rating, and whether AGM is required via the owner’s manual, the battery label, or by checking with a dealer using your VIN, and replace with an OEM‑approved battery to ensure compatibility and reliability.
