OPTIMA® BLUETOP® battery delivers the power you can rely on. Its patented SPIRALCELL TECHNOLOGY® means more running time, faster recharge, and up to twice the life of traditional marine batteries. And it’s specifically built to handle the demanding challenges of marine applications.
The OPTIMA® BLUETOP BT SLIM 4.2 battery is completely spill-proof and maintenance-free. It’s lightweight and can be mounted virtually anywhere and in any position. It’s over 15 times more resistant to vibration than other batteries, which matters in the hull of a boat. And it retains its charge longer and recharges faster thanks to its remarkably low self-discharge rate. And that can mean a quicker return to the water after the off-season.
OPTIMA’s BT SLIM 4.2 BLUETOP battery is a starting battery. Although you can use a deep-cycle battery in any application, starting batteries can only be used for starting applications.
