The 2015 Chevrolet Equinox uses a standard 12-volt automotive lead-acid battery. In practice, most replacement batteries are conventional flooded lead-acid units in a Group Size 75 or 78 (with variations by engine and trim), though some aftermarket options may use AGM. Always verify the exact specification on the battery label or in the owner's manual.
Battery type and common sizes for the 2015 Equinox
This section explains the typical battery category and what to look for when shopping for a replacement.
What to know about the battery type
The Equinox does not require a special high-voltage or lithium battery; it runs on a standard 12-volt lead-acid battery. Some models or aftermarket replacements offer AGM (absorbed glass mat) versions, but the factory setup is usually a flooded lead-acid battery. The vehicle’s battery management system helps monitor charge and health.
Before choosing a replacement, you should confirm the correct group size, CCA rating, and terminal configuration for your exact vehicle.
Common group sizes and specs to consider
- Group size: Common options for the Equinox include 75 (or 75R) and 78 (or 78R) depending on the model year, engine, and regional supplier. Check the battery label or your owner's manual for the precise size.
- Cold-cranking amps (CCA): Typically in the range of 720–800 CCA for many Equinox configurations, ensuring reliable starting in cold weather.
- Reserve capacity (RC): Often around 110–140 minutes, indicating how long the car can run on the battery if the alternator is not charging.
- Battery type and features: Most factory batteries are flooded lead-acid; AGM replacements are available but ensure compatibility with your vehicle's charging system and the battery hold-downs.
- Terminal layout: Most GM 2015 models use top-post terminals; verify terminal position (left or right) to match your cables or clamps.
Always verify the exact battery specification by checking the label on your current battery or consulting your owner's manual or a Chevrolet parts advisor. Using an incorrect group size or CCA can lead to starting problems or electrical issues.
How to identify the correct battery for your car
Use the following steps to confirm the right battery before purchasing:
- Locate your current battery and read the label for group size, CCA, and RC.
- Consult the owner’s manual or Chevrolet’s official parts catalog for the exact specification by VIN or engine type.
- Consider replacing with the same group size and an equal or higher CCA; ensure compatible terminal posts and cable connections.
After selecting the battery, follow standard replacement steps and ensure proper disposal of the old battery at an authorized recycling facility.
Why it matters
A correct battery ensures reliable starting, proper charging by the alternator, and compatibility with the vehicle’s electrical system. Using the wrong size or a non-compatible AGM option can cause charging or fitment issues.
Summary
The 2015 Chevy Equinox runs on a 12-volt lead-acid automotive battery, with common replacement group sizes typically falling around 75 or 78, depending on engine and trim. Most are flooded/wet batteries, though AGM alternatives are available aftermarket. Always verify the exact group size, CCA, RC, and terminal configuration on the current battery or in the owner's manual, and consult a dealer or parts retailer if in doubt.
Summary: For a 2015 Equinox, start with a conventional 12V lead-acid battery in a compatible group size (commonly 75 or 78) and match the CCA/RC to your climate and driving needs. Always check the label or manual to confirm the exact specification.
