For the 2007 Acura TL, replacement batteries are typically Group Size 65 (12V).
In practice, most TL models with the 3.2-liter V6 use a Group 65 battery. The exact CCA and RC can vary by climate and spec, but common OEM-equivalent specs are around 600-750 cold-cranking amps (CCA) and 110-125 minutes of reserve capacity (RC). When shopping, verify the battery label or consult the owner's manual to confirm the precise group size and terminal layout before purchasing.
Understanding the TL battery size and fit
The TL's electrical system is designed around a 12-volt lead-acid battery, with a Group Size 65 being the standard fit for most trims. Some replacements and aftermarket options offer the same footprint with different CCA ratings or AGM construction. Always confirm fitment by checking the label on your current battery or the owner's manual.
Common replacement options
There are several batteries that fit Group 65 and are commonly chosen by TL owners. The list below highlights typical choices, including standard flooded lead-acid and AGM variants.
- Group Size 65 flooded lead-acid battery: typically 600-750 CCA, RC around 110-125 minutes.
- Group Size 65R variant: same physical size but with reversed terminal layout; verify connector orientation.
- 65 AGM option: higher CCA and longer life; compatible with TL charging system if the alternator supports AGM charging.
Conclusion: When choosing a replacement, match the CCA rating to your climate (higher in cold regions) and ensure the terminal layout and fit under the hood.
How to verify the correct size for your vehicle
To confirm the exact battery you need, follow these checks and references:
- Check the current battery’s group size code on the label (often 65) and note the CCA and RC ratings.
- Consult the owner's manual or a dealer for the OEM battery specification for your trim and production date.
- Use your VIN to look up the exact OEM battery part number and recommended replacement on Acura’s service site or parts catalogs.
- Measure the battery space and compare terminal configuration (positive/negative terminal positions) to ensure a proper fit.
Conclusion: Verifying with the current part, manual, and VIN helps prevent buying a battery that physically fits but doesn’t match the electrical or terminal layout.
Summary
For a 2007 Acura TL, the standard replacement size is Group Size 65, with typical CCA around 600-750 and RC about 110-125 minutes. You can choose a flooded lead-acid 65 or an AGM variant, but you should confirm fitment, terminal layout, and climate-appropriate CCA by checking the current battery label, the owner's manual, or a VIN-based parts lookup to ensure you get the exact OEM spec for your vehicle.
