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)

What gets you on the water must get you back on land just as safely. The OPTIMA® BLUETOP® battery offers the performance you can rely on. Thanks to the patented SPIRALCELL TECHNOLOGY®, it can provide power for longer, has a shorter charging time and twice the service life of conventional boat batteries. And it is specially designed to meet the demanding challenges of maritime applications.The OPTIMA BLUETOP battery is completely leak-proof and maintenance-free. It is lightweight and can be installed practically anywhere in almost any position. The vibration resistance of this battery is 15 times higher than that of other batteries, which is extremely important in maritime applications. It also holds its charge longer and can be recharged faster thanks to its remarkably low self-discharge rate. This means you can be back on the water faster at the start of the season.BLUETOP® deep-cycle batteriesOPTIMA BT DC 4.2 and BT DC 5.5 BLUETOP batteries fulfill two tasks. They are suitable for all deep-cycle applications (boat accessories, wheelhouse loads, electric motors, bow thrusters) and for starting applications.BLUETOP SLI (Starting, Lighting, Ignition)The BT SLI 4.2 BLUETOP battery from OPTIMA is a starter battery. While you can use deep-cycle batteries in any application, starter batteries are only suitable for starting applications. Advantages: Starter and dual-purpose models (starter and deep-cycle battery) available. Lasts up to three times longer than other batteries. More power in the first 10 seconds of starting than comparable conventional lead-acid batteries. Consistent power quality - ensures the power of your battery throughout the discharge process. Ideal for seasonal use - can still provide the power required to start a boat engine when fully charged after 12 months storage at room temperature (or below). 15 times higher vibration resistance than other batteries. Leak-proof, flexible and can be installed in almost any position.
