Dual power battery: the Optima Yellwo Top is a starter battery and supply battery in one. Particularly suitable for motorhomes and cleaning machines.When you buy an Optima YELLOW TOP battery, you are choosing a quality product.Agricultural and construction machinery is used seasonally and requires outstanding starting performance. The patented SpiralCell® technology, a special feature of OPTIMA® batteries, makes it possible to reliably start heavy diesel engines even after long periods of standstill and in cold weather. Their low self-discharge makes OPTIMA® batteries ideal for seasonal applications. OPTIMA® batteries also offer unsurpassed vibration resistance compared to conventional lead-acid batteries: their resistance is up to 15 times higher. This proves advantageous for machines that are used in a stony, uneven environment and are exposed to strong vibrations. The firmly compressed cells in the battery enable a leak-proof design and prevent the loss of active material even in the event of strong vibrations. The loss of active material would reduce the capacity and starting power of a battery. However, OPTIMA® batteries are able to withstand rough terrain and demanding requirements without interrupting performance, increasing productivity and efficiency. Performance features:Dual power batteries for starter and traction applicationsDouble the service life of conventional batteriesConstant power output ensures consistent operation even during dischargeOPTIMA has greater power in the first 1, 2, 5 and 10 seconds when starting the vehicle compared to standard lead-acid batteries of the same sizeIdeal for seasonal use. Problem-free vehicle starting at any time after storage in charged condition for 12 months at room temperature (or lower)15 times the vibration resistance of other batteriesLeak-proof and can be mounted in almost any position.Would you like more information?The following link will take you to the manufacturer's website: www.optimabatteries.com/de-de (German) www.optimabatteries.fr/fr-fr (french)www.optimabatteries.com (english)
