The 2008 Sentra typically uses a Group 35, 12-volt lead-acid battery, with cold-cranking amps (CCA) around 550–650 depending on climate. Always verify the exact specification on the battery label or in the owner's manual.
The model year spans two gasoline engines (1.8L and 2.0L) and various trims, but the standard replacement size is Group 35 for most configurations. Climate and driving patterns can influence the recommended CCA, but the group size is generally 35. The sections below summarize the common size and how to choose the right battery.
Common battery size for the 2008 Sentra
Here is the basic group size you'll look for when replacing the battery on most 2008 Sentra models.
- Group Size 35 (12-volt lead-acid battery).
Using the correct group size ensures proper fit, mounting, and terminal orientation. If you're replacing a battery with a non-standard configuration, verify with the manual or a parts specialist.
Recommended CCA ranges for climate and usage
Cold-cranking amps indicate starting power. The following ranges help you choose an appropriate CCA for your climate.
- Typical CCA range: 550–650 CCA for standard climates; consider up to 750 CCA for very cold climates or heavy electrical demands.
Choosing a battery with a higher CCA than the minimum is generally acceptable if it matches the group size and terminal layout, but it won't fix underlying charging or electrical issues. Consult a parts professional if unsure.
How to verify the exact spec
The most reliable method is to check the battery label for Group Size and CCA, refer to the owner's manual, or contact a Nissan dealer or trusted parts retailer with your vehicle VIN.
Summary
The 2008 Nissan Sentra most commonly uses a Group Size 35, 12V battery, with typical CCA in the 550–650 range, and higher CCA recommended for colder climates or heavier electrical use. Always confirm the exact specs on the current battery or in the manual before purchasing a replacement.
