Optima Dual Post 800 CCA Marine Battery (Group Size-34M)

Also referred to as #34M in the Optima Battery Application Guide. Optima battery is the most advanced engine starting battery available today. The patented SPIRALCELL Technology provides many features and benefits not found in conventional automotive batteries. The Optima's SPIRALCELL Technology provides more power for faster, crisper starts. The OPTIMA Blue Top battery will keep you on the water longer. Its patented SPIRALCELL Technology means more running time, faster recharge, and up to twice the life of traditional marine and RV batteries. OPTIMA Blue Top Marine batteries use the same unique SPIRALCELL Technology which Optima engineers incorporate in the Optima Red Top Batteries and the Optima Yellow Top Batteries. OPTIMA Batteries uses high purity lead plates wound with a glass mat that absorbs electrolyte like a sponge. Blue Top Batteries offer clean, reliable, high-power output and deep cycle characteristics that have made OPTIMA batteries your one and only choice for marine applications.

In the off-season, sometimes marine batteries sit for months at a time and lose their charge. But the OPTIMA Blue Top battery has such a low rate of self-discharge, that it can go unused for up to one year without recharging, if kept at or below room temperature. And because of its low internal resistance, it recharges faster, getting you back on the water quickly.

The OPTIMA Blue Top is over 15 times more resistant to vibration than other batteries. The constant vibration and jarring from waves can be deadly for traditional marine batteries. The tightly wound construction in OPTIMA batteries minimizes plate movement and subsequent damage caused by harsh conditions - extending battery life. The OPTIMA is spill-proof and maintenance free. Because of its completely sealed case, OPTIMA batteries are extremely safe. Acid can't leak or spill, making them clean, user-friendly and environmentally sound. In addition, the maintenance free sealed case design eliminates the need to add water or clean terminals. OPTIMA Blue Top batteries are spill proof, so they can be mounted anyplace inside a boat or RV, in almost any position.

 
The OPTIMA Blue Top Marine Deep Cycle battery has been verified in Life Cycle testing to exceed 350 complete discharges.

The Blue Top provides high power output faster and longer than conventional batteries, resulting in greater cranking ability

and less capacity reduction at high current loads.
