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.
