The 2011 Acura RL uses a standard 12-volt automotive battery. In most markets, the factory-installed unit is a Group 35 size, typically delivering about 640–700 cold-cranking amps (CCA) and around 70–75 amp-hours (Ah). Exact specifications can vary by market and equipment, so always verify with the vehicle’s label or owner’s manual.
Battery basics and fitment
Understanding battery group sizes helps ensure you buy a unit that fits physically and powers the car reliably. The RL’s battery is located under the hood in the engine bay, and the correct size must align with the tray, terminal layout, and electrical connections. While Group 35 is common for this model, regional variations or dealer-installed options can slightly alter the expected size.
Group sizes commonly used
Below are the group sizes most often seen as replacements for the 2011 RL. The exact fit for your car should be confirmed with the label on the existing battery or by checking the owner’s manual.
- Group 35 — 12V battery, typical CCA around 640–700, reserve capacity around 100–120 minutes, and roughly 70–75 Ah.

Note: While Group 35 is the most common fit for the RL in many markets, always verify the exact size for your vehicle’s trim and production region, as specifications can vary.
How to confirm the exact size for your specific RL
To ensure you install the correct battery, follow these steps to verify the exact size and specification for your car.
- Check the under-hood battery label, which shows the group size (e.g., Group 35), CCA, and Ah.
- Consult the owner's manual or Acura service documentation for the recommended battery group size for your year and market.
- If you’re purchasing from a parts retailer, provide your VIN to confirm the exact compatible battery size for your RL.
Following these steps helps ensure proper fitment, electrical performance, and compatibility with any on-board battery monitoring systems.
Practical tips for replacement
When replacing the battery, consider choosing a unit that meets or exceeds the OEM CCA if you live in a colder climate. Ensure proper cleaning of cable terminals, apply anti-corrosion protection, and dispose of the old battery at an approved recycling site. If your RL has any unique electrical options or a newer battery management system, confirm compatibility with the replacement battery to avoid warning lights or charging issues.
Summary
For the 2011 Acura RL, the typical factory battery is a 12-volt Group 35 unit with about 640–700 CCA and 70–75 Ah.
