Stock battery size for the 2006 TL
The original equipment battery installed at the factory is a Group 35, 12-volt lead-acid unit. This size fits the TL’s engine bay for all trims in 2006. Some drivers in very cold climates or with aftermarket equipment may opt for higher-CCA replacements, but Group 35 remains the standard specification for the 2006 TL.
What to consider when replacing
To confirm the exact size for your car, use these steps:
- Check the label on your current battery for the group size (for example, “35”) and the cold-cranking amps (CCA).
- Consult the owner’s manual or Acura service data for the recommended group size for your specific trim and market.
- If the label is unreadable, compare the dimensions of the existing battery to standard Group 35 batteries or have a parts store read the information from the car’s VIN and model year.
- When shopping, choose a Group 35 12-volt battery with CCA equal to or greater than the minimum recommended by Acura for your climate (often about 640–700 CCA).
In practice, sticking to a Group 35 with similar or higher CCA ensures proper fit and starting performance. If you live in extremely cold regions or use the car with demanding electronics, consider an AGM variant within Group 35 as an upgrade.
Summary: The 2006 Acura TL typically uses a Group 35, 12-volt battery. Verify the exact size on your current battery or in the owner's manual, and match the group size and ample CCA when replacing to ensure proper fit and performance.
