- The OPTIMA BlueTop battery will keep you in the water longer. Optima will give you longer uptime, faster recharging and twice the life    compared to traditional marine batteries.
- Hermetic/maintenance free
OPTIMA batteries are 15.0 times more resistant to vibration than other batteries. Constant vibrations and jolts from waves can be lethal for conventional marine batteries. The wrap-around design of OPTIMA batteries minimises grid movement and damage caused by extreme conditions, prolonging battery life.
Acid cannot leak and batteries remain clean, easy to handle and environmentally friendly.
The maintenance-free casing design eliminates the need to add water or clean the terminals.
OPTIMA Blue Top batteries are hermetically sealed and can therefore be mounted anywhere and in almost any position within a boat or recreational vehicle. In the off-season, marine batteries remain inactive for months and self-discharge. OPTIMA BlueTop Deep Cycle marine batteries have a very low self-discharge, so that they can remain dormant for up to a year without being recharged, if kept at room temperature. In addition, due to the low internal resistance, they recharge faster, allowing you to get back on the water quickly. Optima BT DC 4.2 and BT DC 5.5 are batteries with dual polarity. They can be used in any deep discharge application: marine services, solar panels, electric motors, bow thrusters, and can also be used in starting applications.
