Answer: The standard replacement size for most 2017 Ram 1500 models is Group Size 65. The exact size can vary with engine and options, so it’s important to verify before purchasing.
In detail, the 2017 Ram 1500 uses a 12-volt automotive battery. While Group Size 65 covers the majority of builds, some configurations with heavier electrical loads or start-stop features may require a different size or an AGM (absorbed glass mat) type. Always confirm the correct size by checking the current battery label, the owner’s manual, or by consulting a dealer or parts professional using your vehicle’s VIN.
How to confirm the correct battery size for your Ram 1500
To ensure you get a battery that fits and delivers proper cranking power, follow these steps.
- Check the current battery label for the Group Size (often shown as a number such as 65) and the cold-cranking amps (CCA) rating.
- Consult the Ram 1500 owner’s manual or service manual for the OEM battery group size specified for your trim and engine.
- Use your vehicle identification number (VIN) at a local dealer or trusted parts store to pull the exact OEM specifications for your truck.
- When shopping, match or exceed the OEM CCA and reserve capacity (RC) requirements and ensure the battery terminal configuration (top-post vs. side-terminal) matches your truck.
- If you have start-stop equipment or large electrical upgrades, consider an AGM battery as recommended by the manufacturer or a qualified technician.
Concluding: Always verify with the VIN and current battery label; using the correct group size and electrical specifications helps ensure reliable starts and optimal battery life.
Additional considerations
In practice, most 2017 Ram 1500s that use the standard starting system will do well with Group Size 65. If your Ram has special equipment, aftermarket accessories, or start-stop capability, consult a professional to confirm whether you should opt for an AGM or a different group size to maintain reliability and warranty compliance.
Summary
For a 2017 Ram 1500, the typical battery size is Group Size 65. Verify the exact size using the current battery label, the owner’s manual, or by querying a dealer with your VIN. If your truck has higher electrical demands or start-stop technology, an AGM option or a different group size may be recommended. When in doubt, have a professional install the replacement to ensure proper fit and performance.
