The 2017 Nissan Altima uses a standard 12-volt automotive battery that powers starting and electrical systems. The exact size can vary by trim and regional market, so you should verify by checking the battery label, the owner's manual, or with a Nissan dealer or trusted parts vendor.
Battery type and common sizes
Most 2017 Altima models come with a conventional 12-volt flooded lead-acid battery. Some regions or dealer-installed options may offer an AGM (absorbed glass mat) battery as an upgrade, but the OEM setup is typically a standard 12-volt lead-acid unit designed to handle the car’s electrical load. The key requirement is a 12-volt battery with enough cold-cranking amps (CCA) for your climate.
Before listing the common sizes, it’s important to note that manufacturers specify group sizes to fit the battery tray, terminals, and electrical demands. Below are the sizes you are most likely to encounter for replacement.
- Group 24F
- Group 35
In practice, the exact group size depends on the vehicle's production year, trim level, and regional supplier. Check the current battery's label or the owner's manual to determine the correct fitment for your specific VIN.
How to identify the correct battery for your Altima
Use these steps to verify the correct 12V replacement for your 2017 Altima. The following guidance helps you confirm fitment and performance requirements before purchasing.
- Inspect the existing battery for a group size and CCA rating printed on a label on the top or side.
- Consult the owner's manual or the Nissan parts catalog for the exact specification recommended for your trim and VIN.
- Match the replacement battery’s physical dimensions, terminal layout, and connector positions to the current one.
- For confidence, have a professional install the battery to ensure compatibility with vehicle electronics and security systems.
Following these steps helps ensure you replace with a battery that fits and meets the Altima's electrical demands.
Summary
The 2017 Nissan Altima uses a standard 12-volt lead-acid car battery, with common replacement group sizes including 24F and 35 depending on trim and region. Always verify the exact specification from the battery label, the owner's manual, or a Nissan dealer to ensure proper fitment and adequate cold-cranking amps for your climate.
