Optima Blue Top battery

The Optima Blue Top comes in two varieties, which makes it ideal for use in all marine applications. One version is a powerful starter battery that, even when operating in the wettest conditions, or in situations where the battery has not been in use for long periods, delivers maximum power. The other version is a starter/deep cycle battery that also provides power to all your onboard equipment and accessories. This makes Optima Blue Top the natural choice for any boat that needs to combine different battery requirements depending on the usage, environment and power needs.

Blue Top marine battery

Installing an Optima Blue Top high-performance AGM battery in your boat or RV means exceptional running time and more recharges than you’d get out of a traditional lead-acid battery. It’s perfect for boats with trolling motors, extensive electronic systems, or RVs with creature comforts that tend to drain batteries quickly. On top of providing outstanding vibration resistance, the Blue Top’s efficient power delivery and faster recharge time mean you’ll spend less time worrying about your battery. This means more time for fun. Again and again. This battery is ideal for those who need a sure-starting, strong-cranking, maintenance-free power source.

Blue Top battery benefits:

  • Both dual-purpose and starting applications available
  • Up to three times more recharges
  • More than 15 times the vibration resistance
  • Spillproof, mountable in virtually any position
  • Maintenance-free
  • Optimal starting power (Dual purpose and starting applications available)
