Optima akude laadimiseks on parimaks tunnistatud Ctek akulaadijad.

OPTIMA aku põhineb spiraaltehnoloogial SPIRACELL TECHNOLOGY- registreeritud kaubamärk.

Aku koosneb 6-st löögikindlast plastikust valmistatud purgist, millesse on paigutatud spiraalsed elemendid. Iga element koosneb tihedalt kokkusurutud + ja - plaadist, mille vahel on elektrolüütidiga immutatud klaaskiudseparaator. Elemendid on ühendatud vahesildadega, millest üks toimib lühise korral sulavkaitsmena. Aku on laserkeevituse abil suletud kaanega, milles paiknevad sädemekindlad ülerõhuklapid.

The OPTIMA YELLOWTOP® is the ideal battery for modern accessory-loaded vehicles, such as caravans, 4x4s and commercial cleaning applications. The YELLOWTOP can be repeatedly brought back from deep power drains to full charge, so it can power plenty of electronics and still start you up time after time. 

OPTIMA® SPIRALCELL TECHNOLOGY® takes AGM to a much higher level.  Pound for pound OPTIMA performance is unmatched.  Here are some OPTIMA SPIRALCELL Facts:

• At the heart of every OPTIMA battery is a series of individual spiral-wound cells comprised of two pure (99.99%) lead plates coated in a precise coating of lead oxide. One coated plate is positive and the other is negative.
• Each lead plate is manufactured as a continuous 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:  Keep the two plates from touching, and hold 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 made 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 6 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 over 100 million individual spiral cells since the early 1990’s.  No one knows how to build the highest quality and best performing spiral-wound batteries better than OPTIMA.

Charging Info

• Deep cycling and cranking power all packed into one battery.
• Lasts up to 2 times longer than traditional flat-plate batteries.
• Constant performance quality, which keeps your battery running at the same level even as it's being discharged.
• More power in the initial 1, 3, 5, and 10 seconds of the starting process than comparably rated conventional lead-acid batteries.
• Ideal for seasonal use, fully charged it can sit unused for up to 12 months at room temperature (or below) and still start a vehicle.
• 15 times more resistant to vibration than traditional lead-acid batteries.
• Mountable in almost any position.
