Make sure you have a good understanding of your car’s battery location and type. Consult your owner’s manual or look for a diagram in the glove compartment. If you’re not sure, consult with a mechanic or a car expert.

Choosing the Right Battery

When selecting a new car battery, make sure it’s the correct type and size for your vehicle. You can find this information in your owner’s manual or on the manufacturer’s website. Here are some things to consider:

• Size: Make sure the new battery is the correct size for your vehicle. You can find this information in your owner’s manual or on the manufacturer’s website.
• Cold Cranking Amps (CCA): This measures the battery’s ability to start the engine in cold temperatures. A higher CCA rating means the battery can start the engine more easily.
• Reserve Capacity (RC): This measures the battery’s ability to power the electrical system while the engine is off. A higher RC rating means the battery can power the electrical system for longer.

Understanding Battery Ratings

When shopping for a new car battery, you’ll come across various ratings and specifications. Here’s a brief explanation of what they mean:
