- 3.8-liter V6 GT: typically Group 35, 12-volt lead-acid battery, with higher CCA rating around 600–800 to support the V6 engine and electrical loads.
Note: Some replacements may use alternative group sizes such as 24, 34/78, or others depending on aftermarket supplier or regional availability. Always confirm with the label on the old battery or consult the owner’s manual.
How to verify the correct size for your car
To ensure you buy the right battery, check the label on your current battery for the Group Size (e.g., 24F or 35), the required CCA rating, and the reserve capacity. You can also consult the owner's manual or contact a Mitsubishi dealer or reputable auto parts store with your VIN to confirm the OEM specification.
Practical tips for replacement
When replacing, consider the following to ensure longevity and performance:
- Match CCA and RC ratings to your climate and usage. Colder climates benefit from higher CCA and robust RC for cold-start.
- Ensure the terminal orientation and polarity match your car’s harness.
- Install with the engine off and follow proper safety steps; check for corrosion and clean terminals if needed.
Selecting the right battery size is crucial for reliable starting and electrical function in the Eclipse, particularly in cold weather or when using accessories.
