OPTIMA is the most advanced engine-starting battery available. Our patented SPIRALCELL Technology provides many features and benefits not found in conventional automotive batteries:

FASTER, CRISPER STARTS: The OPTIMA's SPIRALCELL Technology provides more power for faster, crisper starts. The 800U and 800S 12 volt models deliver 800 Cold Cranking Amps at 0 degrees fahrenheit. The new deep cycle D750U and D750S deliver 750 CCA's at 0 degrees.

LONGER BATTERY LIFE, GREATER SAVINGS: In performance tests, the OPTIMA lasted three to five times longer than conventional, flat-plate batteries.

COMPLETELY SEALED: Electrolyte in the OPTIMA is completely absorbed. It can't leak even if the battery is cracked open. This means the OPTIMA is safer for people, equipment and the environment.

UNEQUALED VIBRATION RESISTANCE: Vibration is a primary killer of conventional batteries. OPTIMA's tightly wound SPIRALCELL resists jarring and vibration and eliminates plate shedding.

MORE POWER IN ANY CLIMATE: Tests prove the OPTIMA performs better in extreme cold and hot temperatures than conventional lead-acid batteries of similar size.

ZERO MAINTENANCE / NO CORROSION: Thanks to recombinant technology, absorbed electrolyte, and sealed construction, the OPTIMA won't corrode battery terminals, cables or the vehicle. The OPTIMA never needs to have water added.

LONGER SHELF LIFE: With its low rate of self discharge, the OPTIMA can go unused for up to a year without recharging. The OPTIMA is ideal for boats, farm equipment, collector cars and other seasonal equipment.

FASTER RECHARGE: Greater plate surface area and lower internal resistance allow the OPTIMA to be recharged in less time than conventional automotive batteries.

FAST ENERGY RESPONSE: The OPTIMA's low internal resistance provides power faster when demanded by accessories such as stereos, winches,etc.

BETTER RECOVERY FROM DISCHARGE: With 120 minutes of Reserve Capacity and a high-purity lead grid, the OPTIMA is less likely to be damaged by accidental deep discharge. The D750's have 124 minutes of Reserve Capacity with a 65 Ampere Hour Capacity @ C/20 rate..

UNIVERSAL SIZE AND FIT: The OPTIMA fits a wide variety of cars, truck and other equipment. The OPTIMA can be mounted in any position, even upside-down. The OPTIMA's are a group 34 size. L=9 15/16 W=6 7/8 H=7 13/16.

OUTSTANDING WARRANTY: Because the OPTIMA is built for some of the roughest conditions, it's backed by one of the best automotive warranties. See an OPTIMA dealer for complete warranty details.

What makes an OPTIMA Battery better than a conventional battery?

SPIRALCELL DESIGN:
Each individual cell contains only two plates, one positive and one negative. These thin lead plates are wound into a tight spiral and separated by an absorbent glass material. This material is very thin allowing for the lead plates to be closer together. The close proximity of the lead plates enhances the flow of electrical current and lowers the batteries internal resistance delivering higher amounts of power.

The tightly wound cell locks the lead plates in place allowing the OPTIMA to use a higher purity lead that requires fewer alloys to strengthen the plates. With higher lead purity the grid resists corrosion and lasts longer in high temperature environments and lowers the internal resistance.

With this design the OPTIMA can use thinner lead plates allowing more winds per cell increasing the amount of surface area in the cell. This increases the amount of energy stored in the battery.

SEALED CASE DESIGN:
The spiralcells are pressure-inserted into the individual cylinders. There is no free space between the plates preventing shorting between the plates and damage due to vibration.

Once the cells are fitted, electrolyte is injected into each cell and is absorbed by the porous glass separator material like a sponge. This locks the electrolyte in preventing spilling or leaking even if the case is ruptured. It also prevents the active material on the plates from drying out.

With the OPTIMA completely sealed you get a battery that eliminates corrosion, can be mounted in any position and requires no special storage or handing procedures. For additional information on the OPTIMA, click here.
