A 2019 Nissan Altima uses a standard 12-volt lead-acid automotive battery, usually Group Size 35. Always verify the exact spec for your vehicle by checking the battery label or the owner's manual, since climate and trim can influence the needed rating.
Overview: the 12-volt battery in the 2019 Altima
Key facts at a glance
The Altima’s electrical system runs on a conventional 12-volt battery. For most replacements, you’ll be looking for a Group Size 35 battery that fits the car’s tray and terminal arrangement. While flooded lead-acid batteries are standard, some drivers opt for an AGM (absorbent glass mat) battery for improved durability in extreme climates or with heavy electrical use. Always match the battery’s cold-cranking amps (CCA) rating to the climate and the original specification, or exceed it if you drive in very cold or hot conditions.
Common options you will encounter when replacing the 12-volt battery include the following:
- Group size: The typical replacement size for the 2019 Altima is Group Size 35, though regional variations can occur.
- Battery type: Most replacements are standard flooded 12-volt lead-acid batteries; AGM variants are available as upgrades in some markets or from certain aftermarket suppliers.
- Certifications and compatibility: Look for batteries that list compatibility with Nissan vehicles and the 12-volt automotive standard.
- Physical fit: Ensure the replacement fits the battery tray, cable stud locations, and terminal layout without modification.
- Warranty considerations: Replacement batteries commonly come with a 2–4 year warranty, but terms vary by brand and retailer.
Conclusion: This list outlines the typical battery options you’ll encounter when replacing the Altima’s 12-volt battery.
How to verify the exact battery for your car
To avoid guesses, confirm the precise requirements for your Altima using straightforward checks or VIN-based lookup.
- Check the current battery’s label for group size and CCA rating, usually printed on the top or side of the case.
- Consult the owner’s manual or Nissan’s official parts catalog using your vehicle’s VIN to confirm the correct group size and CCA.
- If you’re buying aftermarket, request a battery that matches Group Size 35 and meets or exceeds the original CCA rating for your climate.
- Account for climate: colder regions benefit from higher CCA, while extreme heat can affect battery longevity and performance.
Conclusion: Verifying the exact battery requirements through labeling, manuals, or VIN-based parts lookup ensures compatibility and optimal performance.
Summary
The 2019 Nissan Altima typically uses a 12-volt lead-acid automotive battery, with Group Size 35 as the standard replacement size. Always verify the exact specifications against your current battery, the owner’s manual, or a Nissan dealer using your vehicle’s VIN. When shopping, prioritize the correct group size plus CCA to match climate and temperature conditions, and consider warranty and performance features such as AGM if you want extra durability.
