| Conventional | A traditional flooded battery with liquid electrolyte and a separate acid container. |
| Enhanced Flooded Battery (EFB) | A flooded battery with improved performance and durability. |
| Absorbed Glass Mat (AGM) Battery | A maintenance-free battery with a glass mat separator and no free acid. |
| Start-Stop Battery | A specialized battery designed for vehicles with start-stop technology. |
| Deep Cycle Battery | A battery designed for heavy-duty applications, such as RVs and boats. |
Determining Your Vehicle’s Battery Requirements
To determine the right car battery for your vehicle, you’ll need to consider several factors:
Vehicle Make and Model
Your vehicle’s make and model will play a significant role in determining the right battery for your car. Different manufacturers may have specific battery requirements, so it’s essential to consult your owner’s manual or manufacturer’s website for guidance.
Engine Size and Type
The size and type of engine in your vehicle will also impact the battery requirements. For example, a larger engine will require a more powerful battery to handle the increased electrical demands.
Accessories and Upgrades
If your vehicle is equipped with accessories such as a stereo system, winch, or lift kit, you may need a battery with additional capacity to handle the increased electrical load.
Driving Habits and Climate
Your driving habits and the climate you drive in can also impact the battery requirements. For example, if you live in an area with extreme temperatures, you may need a battery with improved cold-cranking amps (CCA) or hot-cranking amps (HCA) ratings.

Measuring Your Vehicle’s Battery Requirements
Once you’ve considered the factors mentioned above, you’ll need to measure your vehicle’s battery requirements. This can be done by:
Checking the Battery Group Size
The battery group size is the physical size of the battery and is measured in inches. You can find the recommended battery group size in your owner’s manual or on the manufacturer’s website.
Checking the Cold-Cranking Amps (CCA) Rating
The CCA rating measures a battery’s ability to start an engine in cold temperatures. A higher CCA rating indicates a more powerful battery.
Checking the Reserve Capacity (RC) Rating
The RC rating measures a battery’s ability to provide power to the vehicle’s accessories after the engine has been turned off. A higher RC rating indicates a battery with more capacity.
Checking the Maintenance Requirements
Some batteries require maintenance, such as checking the electrolyte levels or adding distilled water. Make sure to consider the maintenance requirements when selecting a battery.
Choosing the Right Car Battery
With the information you’ve gathered, you can now choose the right car battery for your vehicle. Here are some tips to keep in mind:
