A Light Case For Heavy Bass

If you run a big system with massive subs and a full rack of speakers in your wakeboard boat, you need a battery with the ability to power all of your gear and still have enough juice left to fire up your engine when it’s time to go home.

OPTIMA's dual-purpose batteries can get the job done and they're easy to spot. All YellowTop batteries feature light gray cases, as do the D27M, D34M and D31M BlueTop marine batteries. All BlueTops are also equipped with additional threaded top posts for marine applications. Find the right battery and it will keep you powered up all day long.
