CCA (Cold Cranking Amps) measures the battery's ability to start the engine in cold temperatures. RC (Reserve Capacity) measures how long your battery can run essential accessories if the alternator fails.
AGM (Absorbed Glass Mat) batteries generally offer better performance, longer life, faster charging, and are required for vehicles with Start-Stop technology or high electrical demands. Traditional lead-acid batteries are usually less expensive but require more maintenance (if not sealed).
The BCI Group Size (e.g., Group 48, H7) dictates the physical dimensions and terminal locations of the battery. You can find this information in your vehicle's owner's manual or by checking the label on your existing battery.
Most automotive batteries last between 3 to 5 years, though this can vary significantly based on climate, driving habits, and whether the battery is a standard lead-acid or a premium AGM/Lithium model.
Investing in a high-quality replacement battery is essential for vehicle reliability and performance. Whether you need the extreme cold-weather power of a high-CCA AGM battery or a reliable deep-cycle option for auxiliary systems, our curated list provides durable and powerful choices. Review the specifications, confirm your BCI group size, and select the best battery to keep your vehicle running smoothly for years to come.
