The standard 2014 Avalon uses a 12-volt lead-acid battery in Group 24F; the hybrid variant uses Group 35. This distinction matters when shopping for a replacement or jump-starting the car.
In 2014, Toyota offered two powertrains for the Avalon: a gasoline V6 and a Hybrid. The 12V battery powers the vehicle’s electronics and starter system; it is not the high-voltage battery that drives the hybrid system. Replacement options are available in the Group 24F and Group 35 sizes, depending on the drivetrain. Always verify the exact group size on the battery label and in the owner's manual before purchasing.
Non-hybrid 2014 Avalon battery size
The gasoline Avalon uses a Group 24F 12-volt battery. Here are the typical specs you’ll encounter when shopping for a replacement:
- Group size: 24F
- Voltage: 12V (lead-acid)
- Cold-cranking amps (CCA): roughly 550–750 A depending on the model
- Terminal layout: top-post terminals suitable for the Avalon's tray
- Fitment: standard size that fits the engine bay battery bracket
Bottom line: For the 2014 Avalon with the gasoline engine, the standard replacement battery size is Group 24F (12V). Always verify with the battery label and VIN before buying.
Notes on compatibility
Because battery sizes can vary by trim and market, confirm the exact group size from the battery label or owner's manual before purchasing.
Avalon Hybrid battery size
The 2014 Avalon Hybrid uses a 12V battery in Group 35. Here are the typical specs you’ll see for replacement of the hybrid-specific 12V battery:
- Group size: 35
- Voltage: 12V (lead-acid)
- Cold-cranking amps (CCA): approximately 500–650 A depending on the model
- Terminal layout: top-post; confirm orientation for your vehicle
- Location: may be under-hood or in the trunk in some configurations
Bottom line: The 2014 Avalon Hybrid uses Group 35 for the 12V battery; confirm the exact fit with your VIN and battery label.
Additional considerations for hybrids
For hybrids, the 12V battery is separate from the high-voltage traction battery. Replacement should use a battery rated for hybrid-equipped Toyotas to ensure proper charging and system compatibility. If in doubt, consult a technician or your local auto parts professional.
Summary
For the 2014 Toyota Avalon, expect Group 24F for the gasoline model and Group 35 for the hybrid model. Always verify your exact VIN, consult the owner's manual, and confirm the battery label before buying replacements. If you’re unsure, a professional installer or your local auto parts dealer can help ensure you get the correct fit and terminal orientation.
