Frequently Asked Questions

What CCA rating do I need for my motorcycle?

The required CCA rating depends on your motorcycle's engine displacement, compression ratio, and operating climate. Generally, you need 2-3 CCA per cubic inch of engine displacement for standard motorcycles, but high-compression sport bikes may require 4-5 CCA per cubic inch. Cold climates increase requirements by 20-30%. Our calculator considers these factors plus your specific motorcycle type to provide accurate CCA recommendations for reliable starting performance.

How do I choose between AGM, Gel, and Lithium motorcycle batteries?

AGM batteries offer excellent vibration resistance and maintenance-free operation, ideal for most modern motorcycles. Gel batteries provide superior deep-cycle capability for touring bikes with high electrical loads. Lithium batteries offer significant weight savings (60-70% lighter) and faster charging, perfect for racing or sport applications. Consider your priorities: AGM for reliability and value, Gel for deep-cycle needs, Lithium for performance and weight reduction. Climate and charging system compatibility also influence the optimal choice.

How often should I test my motorcycle battery?

Test your motorcycle battery monthly during riding season and every two weeks during storage. Use a digital multimeter to check resting voltage (12.6V+ for healthy battery) and perform load testing quarterly. Before storage, ensure full charge and test specific gravity if serviceable. AGM and Gel batteries need voltage testing only, while conventional batteries require electrolyte level checks. Replace batteries showing consistent voltage below 12.4V, slow cranking, or inability to hold charge after proper charging cycle.
