A battery is just a battery. Right?


The sophistication and number of automotive electronics are drastically increasing. Whether it's original equipment or the accessories you've added, you're drawing more power from your battery than ever before. Choosing the right OPTIMA battery will help you keep the tunes playing, the lights on and the engine starting.


OPTIMA batteries are the choice among performance enthusiasts who want to add more power to their adventures. Thanks to proprietary SPIRALCELL & PUREFLOW TECHNOLOGY®, these batteries are up to 15 times more vibration-resistant, which means they can take a lot of abuse both on and off the road, and provide up to three times the life of a traditional flooded battery.


OPTIMA battery grids are constructed of 99.99% pure lead. The purity of the lead provides lower internal resistance for additional power and quicker recharging, corrosion resistance for longer life and reduced self-discharge when stored on the shelf.


The case straps that connect the cells are far more robust than the tombstone welds commonly found in most other batteries. Those robust connections allow for better transfer of energy, both when you're charging your battery and when you need it to deliver power.


OPTIMA's Absorbent Glass Mat (AGM) separators hold electrolyte like a sponge to eliminate acid spilling. Each maintenance-free battery is also completely sealed, preventing corrosion and acid spills.
