Frequently Asked Questions

What is AGM technology and why is it better?

AGM (Absorbed Glass Mat) batteries use fiberglass mats to absorb the electrolyte, making them spill-proof and maintenance-free. They offer superior vibration resistance, faster recharging, and better deep-cycle capabilities compared to standard flooded lead-acid batteries, making them ideal for modern vehicles with heavy electrical loads.

How do I know which BCI group size my car needs?

The BCI group size is determined by the physical dimensions and terminal configuration of the battery tray in your vehicle. You can find this information in your vehicle's owner's manual, on the label of your current battery, or by using an online battery finder tool based on your car's make, model, and year.

What does CCA mean and how much do I need?

CCA stands for Cold Cranking Amps, which is the amount of current a battery can deliver at 0°F (-18°C) for 30 seconds while maintaining a minimum voltage. You should match or exceed the CCA rating specified by your vehicle manufacturer. Vehicles in very cold climates benefit from higher CCA ratings.

How long should an automotive replacement battery last?

The lifespan varies, but a high-quality AGM battery typically lasts between 3 to 5 years, and sometimes longer under ideal conditions. Factors like extreme temperatures, frequent short trips, and high electrical accessory usage can shorten the lifespan.
