EFB (Enhanced Flooded Battery) adds carbon additives and reinforced separators for 2x the cycle life of SLI\u2014suitable for entry-level start-stop vehicles. AGM (Absorbent Glass Mat) uses a glass fiber separator that absorbs all electrolyte, enabling 3\u20134x the cycle life, spill-proof operation, and superior deep discharge recovery\u2014required for most modern European vehicles with start-stop and regenerative braking. For a complete technical breakdown, see our <a href=\"\/sli-vs-agm-vs-efb-battery-comparison-guide\/\">battery type comparison guide<\/a>.<\/p>\n<h4>How do I select the right battery for my market?<\/h4>\n<p>Battery selection depends on five factors: (1) vehicle types in your market and their OEM battery specifications; (2) climate\u2014cold markets prioritize CCA, hot markets prioritize capacity and heat tolerance; (3) market segment\u2014budget, mid-range, or premium; (4) local standards\u2014JIS (Asia\/Africa), DIN (Europe\/Middle East), BCI (Americas); and (5) electrical load\u2014newer vehicles with infotainment, start-stop, and ADAS require higher capacity and AGM\/EFB technology. For personalized product recommendations: <a href=\"\/contact\/\">contact our technical team<\/a> with your target market and vehicle types.<\/p>\n<h4>What is CCA and why are there different CCA ratings?<\/h4>\n<p>CCA (Cold Cranking Amps) measures a battery\u2019s ability to start an engine in cold temperatures by delivering current for 30 seconds at \u221218\u00b0C while maintaining at least 7.2V. Different standards (SAE, EN, DIN, JIS) use slightly different test protocols and produce different values for the same battery. A battery delivering 600 CCA (SAE) would test approximately 565 CCA (EN) or 500 CCA (DIN). Always confirm which CCA standard your supplier uses. For a complete explanation, refer to the <a href=\"\/technical-data-center\/\">Technical Data Center<\/a>.<\/p>\n<h4>Can I use a standard SLI battery in a start-stop vehicle?<\/h4>\n<p>No. Installing a standard SLI battery in a vehicle designed for AGM or EFB will result in premature failure\u2014typically within 3\u20136 months. Start-stop vehicles cycle the battery 20\u201350 times per day versus once or twice for conventional vehicles. Standard SLI batteries are not designed for this duty cycle. Always replace with the same or higher battery technology than the original equipment. See our <a href=\"\/sli-vs-agm-vs-efb-battery-comparison-guide\/\">battery comparison guide<\/a> for compatibility details.<\/p>\n<h4>How should batteries be stored before sale?<\/h4>\n<p>Proper storage is essential for battery longevity and customer satisfaction: store in a cool, dry environment (15\u201325\u00b0C \/ 59\u201377\u00b0F ideal); keep batteries fully charged (12.6V+ open circuit voltage); recharge every 3 months (flooded) or 6 months (AGM) if not sold; avoid direct sunlight and temperatures above 40\u00b0C (104\u00b0F); never stack batteries more than 3 layers high; never store in a discharged state\u2014sulfation begins immediately and becomes irreversible after 48\u201372 hours; rotate stock (first-in, first-out) to minimize shelf time. For further guidance, refer to our shipping and storage documentation included with every order.<\/p>\n<h3>Partnership and Support<\/h3>\n<h4>Do you offer exclusivity or territory protection?<\/h4>\n<p>Exclusive distribution agreements are available for qualified importers with demonstrated sales volume and market coverage.
