The 2019 Nissan Altima typically uses a standard 12-volt lead-acid car battery, most commonly in Group 35 size.
In more detail, the gasoline-powered Altima relies on a conventional 12V battery to start the engine and power electronics. This is not a high-voltage hybrid battery. Replacement parts follow standard automotive sizing, but exact group size and CCA can vary by trim, market, and climate. The information below outlines the common expectations and how to confirm the correct battery for your car.
Battery type and common specifications
Key specs at a glance
These are typical characteristics you’ll encounter when shopping for a replacement. Exact figures can vary by trim, climate, and regional market.
- Battery type: 12-volt lead-acid battery, usually a conventional flooded design; AGM is not typically required for standard Altima models.
- Group size: Group 35 is common for many 2019 Altima configurations; verify with the current battery label or the owner's manual.
- Cold-cranking amps (CCA): About 600–700 CCA is common to ensure reliable starts in cold weather; you may opt for higher CCA in harsher climates.
- Capacity (Ah): Typically in the 45–70 Ah range, depending on climate and equipment; exact rating is shown on the battery label.
Concluding note: For most 2019 Altima owners, a conventional 12V Group 35 battery with appropriate CCA will fit and perform well. Always confirm by checking the current battery and the owner’s manual.
How to verify the correct battery for your car
Quick verification steps
Before purchasing a replacement, confirm the exact specifications for your vehicle to ensure proper fit and warranty protection.
- Inspect the existing battery label to read the group size (e.g., 35, 24F), CCA, and CA ratings.
- Consult the owner’s manual or Nissan service manual for the recommended group size and minimum CCA for your model year and trim.
- Consider climate and electrical load: in extreme heat or cold, a battery with higher CCA or reserve capacity may be beneficial.
- Ask a professional: provide your VIN to a dealer or parts retailer to pull the exact spec for your car.
Bottom line: match the group size and CCA to your vehicle’s needs, and ensure you’re using a compatible 12V lead-acid battery.
Summary
The 2019 Nissan Altima uses a standard 12-volt lead-acid battery, with Group 35 being a common replacement size and a CCA rating around 600–700 depending on climate. Verify specifications on the current battery or in the owner’s manual, and choose a compatible 12V battery accordingly. AGM is not typically required for non-hybrid Altima models.
