The 2008 Buick Lucerne uses a standard 12-volt lead-acid automotive battery; replacements typically use a Group Size 75 battery with roughly 640–750 cold-cranking amps (CCA), depending on the exact trim and equipment. The exact specification should be verified on the battery label or in the owner's manual.
Battery specifications for the 2008 Lucerne
The Lucerne's electrical system runs on a conventional 12-volt flooded lead-acid battery. Most factory configurations install a maintenance-free unit designed to fit in the engine bay's battery tray on the passenger side. Typical capacity is in the 60–78 Ah range, with CCA generally around 640–750, ensuring reliable starting in cold weather. Replacement batteries should match or exceed these specs and fit the battery tray and terminal layout.
Common battery sizes for this model
These sizes are commonly seen in the Lucerne and similar GM front-wheel-drive sedans from the same era. Always verify your exact vehicle's label before purchasing.
- Group Size 75 (the most common for GM mid-size sedans of this era). Typical ratings around 60–78 Ah and 640–750 CCA.
- Group Size 24F or 34R (occasionally used as alternatives for replacements or after-market upgrades). CCA and capacity vary by model and supplier.
- AGM or enhanced-performance options (rare for 2008 Lucerne, usually only on special packages or aftermarket replacements). AGM batteries offer higher vibration resistance and slower self-discharge but require specific terminal and charging compatibility.
When replacing, ensure the chosen battery matches the vehicle's required group size, terminal orientation, and venting, and that your charger and alternator are compatible with whichever technology you choose.
How to identify the correct battery for your car
To confirm the exact battery for your Lucerne, check the battery label under the hood, which lists the group size (e.g., 75, 24F), CCA, and RC ratings. You can also consult the owner's manual or a dealer parts department with your vehicle identification number (VIN). If in doubt, bring the old battery to a parts counter so staff can match the shape, terminal positions, and size.
You can also inspect the battery tray and terminal layout to ensure compatibility with the replacement, including which side the positive and negative terminals face and the distance between posts.
Summary
The 2008 Buick Lucerne uses a standard 12-volt lead-acid battery, with Group Size 75 being the most common factory choice, typically offering around 640–750 CCA and 60–78 Ah.
