Optima AGM car batteries provide long-lasting performance that many of todays auto professionals and enthusiasts need and demand.This ensures perfect and uniform compression once the SPIRALCELL is inserted and also avoids any potential contaminants or impurities from pre-used plastic Our unique SPIRALCELL TECHNOLOGY gives OPTIMA Batteries over 15 times more vibration resistance. Using or storing batteries in temperatures above 75 F accelerates the rate of self-discharge and increases sulfation dramatically. OPTIMA Batteries deliver supreme performance and reliability. It’s Ideal for seasonal use a fully charged battery can start a car immediately even after 12 months of standstill. Next to their incredible toughness, they have almost twice the lifespan of normal lead-acid batteries. It must be charged enough to prevent the battery from dropping below 12.4 Volts (2.07 volts / cell). Optima Red Top batteries are built to withstand usage in trucks, MPVs and 4x4s, both on the road and in off-road conditions. OPTIMA ® batteries' precision-molded cylindrical cases are manufactured to such tight tolerances that only virgin polypropylene can be used. Even when stored fully charged sulfate will form without a frequently applied maintenance charge.Each completed SPIRALCELL ends up looking somewhat like a precisely wound “jelly roll.” Critical tolerances, temperatures, humidity and automated processes are maintained and constantly monitored. ![]() Custom automated cell-winding machines are required to maintain the close tolerances required to maintain quality and performance The unique manufacturing process of spiral winding continuous lead plates is far more precision-controlled and expensive than building traditional flat-plate AGM batteries.The two plates get a proprietary separator (this key component is actually made of a micro-fiberglass blend that feels like fine cotton) that performs two critical functions: keeps the two plates from touching, and holds the electrolyte in a uniform suspension.Each lead plate is manufactured as a continuously cast strip that maintains critical thickness tolerances.
