Optima D31T Features & Benefits

Spiralcell Technology

• Each lead plate is manufactured as a continuously cast strip that maintains critical thickness tolerances
• 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
• The unique manufacturing process of spiral winding continuous lead plates is far more precision-controlled and expensive than building traditional flat-plate AGM batteries. Custom automated cell-winding machines are required to maintain the close tolerances required to maintain quality and performance
• 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
• OPTIMA batteries' precision-molded cylindrical cases are manufactured to such tight tolerances that only virgin polypropylene can be used. This ensures perfect and uniform compression once the SPIRALCELL is inserted and also avoids any potential contaminants or impurities from pre-used plastic
• 12 Volt OPTIMA batteries are made of six SPIRALCELL cells, each having a fully charged open circuit voltage of 2.2 volts for deep-cycle batteries and just over 2.1 volts for starting batteries OPTIMA has built more than 100 million individual spiral cells since the early 1990s. No one knows how to build the highest quality and best-performing spiral-wound batteries better than OPTIMA.
