OPTIMA® Blue Top® BT SLI 4.2 starter battery

Starting and power battery, specially designed for the demanding challenges of maritime applications (boats, yachts, boats) but also ideal for camping applications.

The BLUETOP SLI (Starting, Lighting, Ignition) battery is a starter battery. Although you can use deep cycle batteries in any application, this starting battery is for starting applications only.

Thanks to the patented SPIRALCELL® TECHNOLOGY, the battery can provide power for longer, has a shorter charging time and a service life twice that of conventional boat batteries

Holds its charge longer and recharges faster thanks to its remarkably low self-discharge rate

Advantage:

Lasts up to three times longer than other batteries.

More power in the first 10 seconds of cranking than comparable conventional lead-acid batteries.

Constant power quality: guarantees the power of your battery during the entire discharge process

Ideal for seasonal use – can still provide the power needed to start a boat engine after 12 months of storage at room temperature (or below) when fully charged

15 times more resistance to vibrations than other batteries (extremely important in marine use)

Completely leak-proof and maintenance-free, it is flexible, lightweight, and can be installed in almost any position.
